Usually, a fever isn’t dangerous or bad for kids. It can even be a good thing because it can help the\nimmune system\nfight infection.\nStill, parents might be unsure about how to handle a fever at home and when to call the doctor. Here are some tips.\nWhat Is a Fever?\nIn general, a fever means the body’s temperature is 100.4°F (38°C) or higher. Different ways of\nmeasuring a temperature\n— rectal, armpit, ear, forehead, mouth — get a slightly different number, so the number that means a child has a fever is a little different too. \nWhat Causes Fevers?\nFevers in kids are usually caused by an infection. A fever helps the body by stimulating the immune system to fight the infection. Doctors also think the higher temperature makes it harder for the germs to grow.\nA few other reasons kids can have a fever:\nOverdressing:\nInfants, especially newborns, may get fevers if they’re overdressed, wrapped in a blanket, or in a hot environment because they don’t regulate their body temperature as well as older kids. But because fevers in newborns can be a sign of a serious infection, even infants who are overdressed must be checked by a doctor if they have a fever.\nImmunizations:\nBabies and kids sometimes get a mild fever that lasts about a day after getting vaccinated.\nA child who is\nteething\nmight have a slight rise in body temperature, but it’s probably not the cause if the temperature is higher than 100°F (37.8°C).\nWhen Is a Fever a Sign of Something Serious?\nIn most healthy kids who are acting well, a fever isn’t serious.\nBut a fever can be serious for:\nInfants younger than 3 months:\nIf an infant younger than 3 months has a rectal temperature of 100.4°F (38°C) or higher, call your doctor or go to the emergency department right away.\n \nKids with some health conditions: If your child has an ongoing health issue, make sure you know if the doctor should be called for fever.\nA fever is probably not serious if your child is 3 months or older and:\nis still interested in playing\nis drinking well\nis alert and smiling\nhas a normal skin color\nlooks well when their temperature comes down\nDon’t worry too much about a child with a fever who doesn’t want to eat. This is common with infections that cause fever. For kids who still drink and urinate (pee) normally, not eating as much as usual is OK.\nWhat Are the Signs of a Fever?\nKids with a fever might:\nfeel warm\nact differently (they might be fussy or cranky, or quieter than usual)\nbreathe a little faster or have a faster heart rate than normal\nhave a headache\nhave chills or sweating\nhave red or flushed skin\nFor any of these signs, take your child’s temperature to know if they really have a fever.\nIf your child feels warm or is acting unwell, use a\ndigital thermometer\nto confirm a fever. Different ways of taking the temperature are more accurate than others at measuring the true body temperature.\nThe best way to take a temperature:\nfor kids 3 years old and younger: a\nrectal temperature\nfor kids 4 or older who can cooperate: an\noral temperature\n(by mouth)\nfor any age: under the armpit (\naxillary\n) and temporal artery (forehead) are easiest but less accurate. Tympanic (in the ear) is OK for kids 6 months and older.\nIt’s a fever when a child’s temperature is at or above one of these levels:\nrectal (in the bottom), tympanic (in the ear), or temporal artery (across the forehead): 100.4°F (38°C)\noral (in the mouth): 100°F (37.8°C)\naxillary (under the arm): 99°F (37.2°C)\nHow Can I Help My Child Feel Better?\nNo treatment is needed if a child is still playing and drinking normally and doesn’t have pain. \nTreating a fever with medicine isn’t needed if a child is still playing and drinking normally and doesn’t have pain. Give medicine\nonly\nwhen a fever causes a child discomfort or keeps them from drinking.\nWhile kids\nhave a fever\n, keep an eye on them, help them to rest, and keep offering fluids to drink. They need to drink a little extra to make up for the fluids they lose from sweating.\nHome Care Measures\nMedicines\nIf your child is uncomfortable from a fever or not drinking fluids well, you can give one of these medicines:\nacetaminophen\n(such as Tylenol or a store brand)\nor\nibuprofen\n(such as Advil, Motrin, or a store brand). Do not give to children under 6 months old.\nFollow the package directions for how much to give and how often. If you don’t know the recommended dose\nor your child is younger than 2 years old\n, call the doctor to find out what to use and how much to give.\nIf your child has any medical problems, check with the doctor to see which medicine to use.\nUnless instructed to by a doctor, never give aspirin to a child. Such use is linked to \nReye syndrome\n, a rare but serious illness.\nDo not give any medicine for fever to infants younger than 3 months old unless instructed to by a doctor.\nStaying Comfortable\nIf your child has a fever:\nHave them wear lightweight clothing and stay covered with a light sheet or blanket. Heavy clothes and blankets can keep the body from cooling, which can make your child uncomfortable.\nKeep the room at a comfortable temperature — not too hot or too cold.\nMake sure they get plenty of rest. Staying in bed all day isn’t necessary, but a sick child should take it easy.\nThey should stay home from school or childcare until their temperature has been normal for 24 hours.\nLukewarm sponge baths to lower a fever generally are not recommended. In fact, sponge baths can make kids uncomfortable from shivering. Never use rubbing alcohol (it can cause poisoning when absorbed through the skin) or ice packs\/cold baths (they can cause chills that can raise body temperature).\nFood and Drinks\nOffer plenty of fluids to avoid\ndehydration\nbecause fevers make kids lose fluids faster than usual. Oral rehydration solutions (like Pedialyle, Enfalyte, or store brands) are a good choice. You also can give water, soup, ice pops, and flavored gelatin. Avoid drinks with caffeine, including colas and tea, which can make dehydration worse by making kids pee more often.\nLet kids eat what they want (in reasonable amounts), but don’t force it if they don’t feel like eating much.\nWhen Should I Call the Doctor?\nThe temperature that should trigger a call to the doctor depends on a child’s age, the illness, and whether they have other symptoms. You might ask if your doctor has specific guidelines on when to call about a fever.\nIn general, call the doctor if your child is:\nyounger than 3 months old with a rectal temperature of 100.4°F (38°C) or higher\n3 months or older with a temperature higher than 102.2°F (39°C)\nany age but has a health problem like cancer or sickle cell disease and has a fever\nAlso call if a child 3 months or older has a fever and:\nrefuses fluids or seems too ill to drink enough\nhas lasting\ndiarrhea\nor repeated\nvomiting\nhas any signs of dehydration (peeing less than usual, not having tears when crying, less alert and less active than usual)\nhas a specific complaint (like a\nsore throat\nor earache)\nstill has a fever after 2–3 days\nhas a rash\nhas pain while peeing\nGet\nemergency care\nif your child shows any of these signs:\ncrying that won’t stop\nextreme irritability or fussiness\nsluggishness and trouble waking up\na rash or purple spots that look like bruises on the skin (that were not there before your child got sick)\nblue lips, tongue, or nails\nin an infant, the soft spot on the head seems to be bulging out or sunken in\nstiff neck\nsevere headache\nlimpness or refusal to move\ntrouble breathing that doesn’t get better when the nose is cleared\nleaning forward and drooling\nseizure\nmoderate to severe belly pain\nWhat Else Should I Know?\nAll kids get fevers, and in most cases they’re back to normal within a few days. For older babies and kids, the way they act can be more important than the reading on your thermometer. Everyone gets a little cranky when they have a fever. This is normal and should be expected.\nBut if you’re ever in doubt about what to do or what a fever might mean, or if your child is acting ill in a way that concerns you even with no fever, always call your doctor for advice.\nNote: All information is for educational purposes only.

Usually, a fever isn’t dangerous or bad for kids.

Such use is linked to [Reye syndrome](https:\/\/www.rchsd.org\/health-article\/reye-syndrome), a rare but serious illness.\n\n**Do not give any medicine for fever to infants younger than 3 months old unless instructed to by a doctor.**\n\n#### **Staying Comfortable**\nIf your child has a fever:\n\n- Have them wear lightweight clothing and stay covered with a light sheet or blanket. Heavy clothes and blankets can keep the body from cooling, which can make your child uncomfortable.\n- Keep the room at a comfortable temperature — not too hot or too cold.\n- Make sure they get plenty of rest. Staying in bed all day isn’t necessary, but a sick child should take it easy.\n- They should stay home from school or childcare until their temperature has been normal for 24 hours.\n\nLukewarm sponge baths to lower a fever generally are not recommended. In fact, sponge baths can make kids uncomfortable from shivering. Never use rubbing alcohol (it can cause poisoning when absorbed through the skin) or ice packs\/cold baths (they can cause chills that can raise body temperature).\n\n#### **Food and Drinks**\nOffer plenty of fluids to avoid [dehydration](https:\/\/www.rchsd.org\/health-article\/dehydration) because fevers make kids lose fluids faster than usual. Oral rehydration solutions (like Pedialyle, Enfalyte, or store brands) are a good choice. You also can give water, soup, ice pops, and flavored gelatin. Avoid drinks with caffeine, including colas and tea, which can make dehydration worse by making kids pee more often.\n\nLet kids eat what they want (in reasonable amounts), but don’t force it if they don’t feel like eating much.\n\n### When Should I Call the Doctor?\nThe temperature that should trigger a call to the doctor depends on a child’s age, the illness, and whether they have other symptoms. You might ask if your doctor has specific guidelines on when to call about a fever.\n\nIn general, call the doctor if your child is:\n\n- younger than 3 months old with a rectal temperature of 100.4°F (38°C) or higher\n- 3 months or older with a temperature higher than 102.2°F (39°C)\n- any age but has a health problem like cancer or sickle cell disease and has a fever\n\nAlso call if a child 3 months or older has a fever and:\n\n- refuses fluids or seems too ill to drink enough\n- has lasting [diarrhea](https:\/\/www.rchsd.org\/health-article\/what-to-do-about-diarrhea) or repeated [vomiting](https:\/\/www.rchsd.org\/health-article\/how-to-handle-vomiting)\n- has any signs of dehydration (peeing less than usual, not having tears when crying, less alert and less active than usual)\n- has a specific complaint (like a [sore throat](https:\/\/www.rchsd.org\/health-article\/what-to-do-about-a-sore-throat) or earache)\n- still has a fever after 2–3 days\n- has a rash\n- has pain while peeing\n\nGet [emergency care](https:\/\/www.rchsd.org\/health-article\/going-to-the-emergency-room) if your child shows any of these signs:\n\n- crying that won’t stop\n- extreme irritability or fussiness\n- sluggishness and trouble waking up\n- a rash or purple spots that look like bruises on the skin (that were not there before your child got sick)\n- blue lips, tongue, or nails\n- in an infant, the soft spot on the head seems to be bulging out or sunken in\n- stiff neck\n- severe headache\n- limpness or refusal to move\n- trouble breathing that doesn’t get better when the nose is cleared\n- leaning forward and drooling\n- [seizure](https:\/\/www.rchsd.org\/health-article\/seizures)\n- moderate to severe belly pain\n### What Else Should I Know?\nAll kids get fevers, and in most cases they’re back to normal within a few days. For older babies and kids, the way they act can be more important than the reading on your thermometer. Everyone gets a little cranky when they have a fever. This is normal and should be expected.\n\nBut if you’re ever in doubt about what to do or what a fever might mean, or if your child is acting ill in a way that concerns you even with no fever, always call your doctor for advice.\n\n*Note: All information is for educational purposes only.

Usually, a fever isn’t dangerous or bad for kids. It can even be a good thing because it can help the [immune system](https:\/\/www.rchsd.org\/health-article\/immune-system) fight infection.\n\nStill, parents might be unsure about how to handle a fever at home and when to call the doctor. Here are some tips.\n\n### What Is a Fever?\nIn general, a fever means the body’s temperature is 100.4°F (38°C) or higher. Different ways of [measuring a temperature](https:\/\/www.rchsd.org\/health-article\/taking-your-childs-temperature) — rectal, armpit, ear, forehead, mouth — get a slightly different number, so the number that means a child has a fever is a little different too.\n\n### What Causes Fevers?\nFevers in kids are usually caused by an infection. A fever helps the body by stimulating the immune system to fight the infection. Doctors also think the higher temperature makes it harder for the germs to grow.\n\nA few other reasons kids can have a fever:\n\n**Overdressing:** Infants, especially newborns, may get fevers if they’re overdressed, wrapped in a blanket, or in a hot environment because they don’t regulate their body temperature as well as older kids. But because fevers in newborns can be a sign of a serious infection, even infants who are overdressed must be checked by a doctor if they have a fever.\n\n**Immunizations:** Babies and kids sometimes get a mild fever that lasts about a day after getting vaccinated.\n\nA child who is [teething](https:\/\/www.rchsd.org\/health-article\/teething-tots) might have a slight rise in body temperature, but it’s probably not the cause if the temperature is higher than 100°F (37.8°C).\n\n### When Is a Fever a Sign of Something Serious?\nIn most healthy kids who are acting well, a fever isn’t serious.\n\n**But a fever can be serious for:**\n\n- Infants younger than 3 months: **If an infant younger than 3 months has a rectal temperature of 100.4°F (38°C) or higher, call your doctor or go to the emergency department right away.**\n- Kids with some health conditions: If your child has an ongoing health issue, make sure you know if the doctor should be called for fever.\n\nA fever is probably not serious if your child is 3 months or older and:\n\n- is still interested in playing\n- is drinking well\n- is alert and smiling\n- has a normal skin color\n- looks well when their temperature comes down\n\nDon’t worry too much about a child with a fever who doesn’t want to eat. This is common with infections that cause fever. For kids who still drink and urinate (pee) normally, not eating as much as usual is OK.\n\n### What Are the Signs of a Fever?\nKids with a fever might:\n\n- feel warm\n- act differently (they might be fussy or cranky, or quieter than usual)\n- breathe a little faster or have a faster heart rate than normal\n- have a headache\n- have chills or sweating\n- have red or flushed skin\n\nFor any of these signs, take your child’s temperature to know if they really have a fever.\n\n![](https:\/\/www.kidshealth.org\/content\/dam\/patientinstructions\/en\/images\/feverMeasure_a_enIL.png)\n\nIf your child feels warm or is acting unwell, use a **digital thermometer** to confirm a fever. Different ways of taking the temperature are more accurate than others at measuring the true body temperature.\n\nThe best way to take a temperature:\n\n- for kids 3 years old and younger: a [rectal temperature](https:\/\/www.rchsd.org\/health-article\/how-to-take-a-rectal-temperature)\n- for kids 4 or older who can cooperate: an [oral temperature](https:\/\/www.rchsd.org\/health-article\/how-to-take-an-oral-temperature) (by mouth)\n- for any age: under the armpit ([axillary](https:\/\/www.rchsd.org\/health-article\/how-to-take-an-axillary-armpit-temperature)) and temporal artery (forehead) are easiest but less accurate. Tympanic (in the ear) is OK for kids 6 months and older.\n\nIt’s a fever when a child’s temperature is at or above one of these levels:\n\n- rectal (in the bottom), tympanic (in the ear), or temporal artery (across the forehead): 100.4°F (38°C)\n- oral (in the mouth): 100°F (37.8°C)\n- axillary (under the arm): 99°F (37.2°C)\n### How Can I Help My Child Feel Better?\nNo treatment is needed if a child is still playing and drinking normally and doesn’t have pain.\n\nTreating a fever with medicine isn’t needed if a child is still playing and drinking normally and doesn’t have pain. Give medicine **only** when a fever causes a child discomfort or keeps them from drinking.\n\nWhile kids [have a fever](https:\/\/www.rchsd.org\/health-article\/what-can-i-do-about-a-fever-high-temperature), keep an eye on them, help them to rest, and keep offering fluids to drink. They need to drink a little extra to make up for the fluids they lose from sweating.\n\n### Home Care Measures\n#### Medicines\nIf your child is uncomfortable from a fever or not drinking fluids well, you can give one of these medicines:\n\n- [acetaminophen](https:\/\/www.rchsd.org\/health-article\/how-to-safely-give-acetaminophen) (such as Tylenol or a store brand)  \n   or\n- [ibuprofen](https:\/\/www.rchsd.org\/health-article\/how-to-safely-give-ibuprofen) (such as Advil, Motrin, or a store brand). Do not give to children under 6 months old.\n\nFollow the package directions for how much to give and how often. If you don’t know the recommended dose **or your child is younger than 2 years old**, call the doctor to find out what to use and how much to give.\n\n- If your child has any medical problems, check with the doctor to see which medicine to use.\n- Unless instructed to by a doctor, never give aspirin to a child. Such use is linked to [Reye syndrome](https:\/\/www.rchsd.org\/health-article\/reye-syndrome), a rare but serious illness.\n\n**Do not give any medicine for fever to infants younger than 3 months old unless instructed to by a doctor.**\n\n#### **Staying Comfortable**\nIf your child has a fever:\n\n- Have them wear lightweight clothing and stay covered with a light sheet or blanket.

Staying in bed all day isn’t necessary, but a sick child should take it easy.\n- They should stay home from school or childcare until their temperature has been normal for 24 hours.\n\nLukewarm sponge baths to lower a fever generally are not recommended. In fact, sponge baths can make kids uncomfortable from shivering. Never use rubbing alcohol (it can cause poisoning when absorbed through the skin) or ice packs\/cold baths (they can cause chills that can raise body temperature).\n\n#### **Food and Drinks**\nOffer plenty of fluids to avoid [dehydration](https:\/\/www.rchsd.org\/health-article\/dehydration) because fevers make kids lose fluids faster than usual.

Usually, a fever isn’t dangerous or bad for kids. It can even be a good thing because it can help the [immune system](https://www.rchsd.org/health-article/immune-system) fight infection. Still, parents might be unsure about how to handle a fever at home and when to call the doctor. Here are some tips. ### What Is a Fever? In general, a fever means the body’s temperature is 100.4°F (38°C) or higher. Different ways of [measuring a temperature](https://www.rchsd.org/health-article/taking-your-childs-temperature) — rectal, armpit, ear, forehead, mouth — get a slightly different number, so the number that means a child has a fever is a little different too. ### What Causes Fevers? Fevers in kids are usually caused by an infection. A fever helps the body by stimulating the immune system to fight the infection. Doctors also think the higher temperature makes it harder for the germs to grow. A few other reasons kids can have a fever: Overdressing: Infants, especially newborns, may get fevers if they’re overdressed, wrapped in a blanket, or in a hot environment because they don’t regulate their body temperature as well as older kids. But because fevers in newborns can be a sign of a serious infection, even infants who are overdressed must be checked by a doctor if they have a fever. Immunizations: Babies and kids sometimes get a mild fever that lasts about a day after getting vaccinated. A child who is [teething](https://www.rchsd.org/health-article/teething-tots) might have a slight rise in body temperature, but it’s probably not the cause if the temperature is higher than 100°F (37.8°C). ### When Is a Fever a Sign of Something Serious? In most healthy kids who are acting well, a fever isn’t serious. But a fever can be serious for: - Infants younger than 3 months: If an infant younger than 3 months has a rectal temperature of 100.4°F (38°C) or higher, call your doctor or go to the emergency department right away. - Kids with some health conditions: If your child has an ongoing health issue, make sure you know if the doctor should be called for fever. A fever is probably not serious if your child is 3 months or older and: - is still interested in playing - is drinking well - is alert and smiling - has a normal skin color - looks well when their temperature comes down Don’t worry too much about a child with a fever who doesn’t want to eat. This is common with infections that cause fever. For kids who still drink and urinate (pee) normally, not eating as much as usual is OK. ### What Are the Signs of a Fever? Kids with a fever might: - feel warm - act differently (they might be fussy or cranky, or quieter than usual) - breathe a little faster or have a faster heart rate than normal - have a headache - have chills or sweating - have red or flushed skin For any of these signs, take your child’s temperature to know if they really have a fever. ![](https://www.kidshealth.org/content/dam/patientinstructions/en/images/feverMeasure_a_enIL.png) If your child feels warm or is acting unwell, use a digital thermometer to confirm a fever. Different ways of taking the temperature are more accurate than others at measuring the true body temperature. The best way to take a temperature: - for kids 3 years old and younger: a [rectal temperature](https://www.rchsd.org/health-article/how-to-take-a-rectal-temperature) - for kids 4 or older who can cooperate: an [oral temperature](https://www.rchsd.org/health-article/how-to-take-an-oral-temperature) (by mouth) - for any age: under the armpit ([axillary](https://www.rchsd.org/health-article/how-to-take-an-axillary-armpit-temperature)) and temporal artery (forehead) are easiest but less accurate. Tympanic (in the ear) is OK for kids 6 months and older. It’s a fever when a child’s temperature is at or above one of these levels: - rectal (in the bottom), tympanic (in the ear), or temporal artery (across the forehead): 100.4°F (38°C) - oral (in the mouth): 100°F (37.8°C) - axillary (under the arm): 99°F (37.2°C) ### How Can I Help My Child Feel Better? No treatment is needed if a child is still playing and drinking normally and doesn’t have pain. Treating a fever with medicine isn’t needed if a child is still playing and drinking normally and doesn’t have pain. Give medicine only when a fever causes a child discomfort or keeps them from drinking. While kids [have a fever](https://www.rchsd.org/health-article/what-can-i-do-about-a-fever-high-temperature), keep an eye on them, help them to rest, and keep offering fluids to drink. They need to drink a little extra to make up for the fluids they lose from sweating. ### Home Care Measures #### Medicines If your child is uncomfortable from a fever or not drinking fluids well, you can give one of these medicines: - [acetaminophen](https://www.rchsd.org/health-article/how-to-safely-give-acetaminophen) (such as Tylenol or a store brand) or - [ibuprofen](https://www.rchsd.org/health-article/how-to-safely-give-ibuprofen) (such as Advil, Motrin, or a store brand). Do not give to children under 6 months old. Follow the package directions for how much to give and how often. If you don’t know the recommended dose or your child is younger than 2 years old, call the doctor to find out what to use and how much to give. - If your child has any medical problems, check with the doctor to see which medicine to use. - Unless instructed to by a doctor, never give aspirin to a child. Such use is linked to [Reye syndrome](https://www.rchsd.org/health-article/reye-syndrome), a rare but serious illness. Do not give any medicine for fever to infants younger than 3 months old unless instructed to by a doctor. #### Staying Comfortable If your child has a fever: - Have them wear lightweight clothing and stay covered with a light sheet or blanket. Heavy clothes and blankets can keep the body from cooling, which can make your child uncomfortable. - Keep the room at a comfortable temperature — not too hot or too cold. - Make sure they get plenty of rest. Staying in bed all day isn’t necessary, but a sick child should take it easy. - They should stay home from school or childcare until their temperature has been normal for 24 hours. Lukewarm sponge baths to lower a fever generally are not recommended. In fact, sponge baths can make kids uncomfortable from shivering. Never use rubbing alcohol (it can cause poisoning when absorbed through the skin) or ice packs/cold baths (they can cause chills that can raise body temperature). #### Food and Drinks Offer plenty of fluids to avoid [dehydration](https://www.rchsd.org/health-article/dehydration) because fevers make kids lose fluids faster than usual. Oral rehydration solutions (like Pedialyle, Enfalyte, or store brands) are a good choice. You also can give water, soup, ice pops, and flavored gelatin. Avoid drinks with caffeine, including colas and tea, which can make dehydration worse by making kids pee more often. Let kids eat what they want (in reasonable amounts), but don’t force it if they don’t feel like eating much. ### When Should I Call the Doctor? The temperature that should trigger a call to the doctor depends on a child’s age, the illness, and whether they have other symptoms. You might ask if your doctor has specific guidelines on when to call about a fever. In general, call the doctor if your child is: - younger than 3 months old with a rectal temperature of 100.4°F (38°C) or higher - 3 months or older with a temperature higher than 102.2°F (39°C) - any age but has a health problem like cancer or sickle cell disease and has a fever Also call if a child 3 months or older has a fever and: - refuses fluids or seems too ill to drink enough - has lasting [diarrhea](https://www.rchsd.org/health-article/what-to-do-about-diarrhea) or repeated [vomiting](https://www.rchsd.org/health-article/how-to-handle-vomiting) - has any signs of dehydration (peeing less than usual, not having tears when crying, less alert and less active than usual) - has a specific complaint (like a [sore throat](https://www.rchsd.org/health-article/what-to-do-about-a-sore-throat) or earache) - still has a fever after 2–3 days - has a rash - has pain while peeing Get [emergency care](https://www.rchsd.org/health-article/going-to-the-emergency-room) if your child shows any of these signs: - crying that won’t stop - extreme irritability or fussiness - sluggishness and trouble waking up - a rash or purple spots that look like bruises on the skin (that were not there before your child got sick) - blue lips, tongue, or nails - in an infant, the soft spot on the head seems to be bulging out or sunken in - stiff neck - severe headache - limpness or refusal to move - trouble breathing that doesn’t get better when the nose is cleared - leaning forward and drooling - [seizure](https://www.rchsd.org/health-article/seizures) - moderate to severe belly pain ### What Else Should I Know? All kids get fevers, and in most cases they’re back to normal within a few days. For older babies and kids, the way they act can be more important than the reading on your thermometer. Everyone gets a little cranky when they have a fever. This is normal and should be expected. But if you’re ever in doubt about what to do or what a fever might mean, or if your child is acting ill in a way that concerns you even with no fever, always call your doctor for advice.

In general, call the doctor if your child is: - younger than 3 months old with a rectal temperature of 100.4°F (38°C) or higher - 3 months or older with a temperature higher than 102.2°F (39°C) - any age but has a health problem like cancer or sickle cell disease and has a fever Also call if a child 3 months or older has a fever and: - refuses fluids or seems too ill to drink enough - has lasting [diarrhea](https://www.rchsd.org/health-article/what-to-do-about-diarrhea) or repeated [vomiting](https://www.rchsd.org/health-article/how-to-handle-vomiting) - has any signs of dehydration (peeing less than usual, not having tears when crying, less alert and less active than usual) - has a specific complaint (like a [sore throat](https://www.rchsd.org/health-article/what-to-do-about-a-sore-throat) or earache) - still has a fever after 2–3 days - has a rash - has pain while peeing Get [emergency care](https://www.rchsd.org/health-article/going-to-the-emergency-room) if your child shows any of these signs: - crying that won’t stop - extreme irritability or fussiness - sluggishness and trouble waking up - a rash or purple spots that look like bruises on the skin (that were not there before your child got sick) - blue lips, tongue, or nails - in an infant, the soft spot on the head seems to be bulging out or sunken in - stiff neck - severe headache - limpness or refusal to move - trouble breathing that doesn’t get better when the nose is cleared - leaning forward and drooling - [seizure](https://www.rchsd.org/health-article/seizures) - moderate to severe belly pain ### What Else Should I Know? All kids get fevers, and in most cases they’re back to normal within a few days. For older babies and kids, the way they act can be more important than the reading on your thermometer. Everyone gets a little cranky when they have a fever. This is normal and should be expected. But if you’re ever in doubt about what to do or what a fever might mean, or if your child is acting ill in a way that concerns you even with no fever, always call your doctor for advice.
