What is a newborn baby normal temperature

Fever (0-12 Months)

Is this your child's symptom?

An abnormal high body temperature
Fever is the only symptom. Your child has a true fever if:
Rectal (bottom), Ear or Forehead temperature: 100.4° F (38.0° C) or higher
Under the arm (armpit) temperature: 99° F (37.2° C) or higher
Caution: Ear temperatures are not accurate before 6 months of age
Caution: Forehead temperatures must be digital. Forehead strips are not accurate.

Causes of Fever

Overview. Almost all fevers are caused by a new infection. Viruses cause 10 times more infections than bacteria. The number of germs that cause an infection are in the hundreds. Only a few common ones will be listed.
Viral Infections. Colds, flu and other viral infections are the most common cause. Fever may be the only symptom for the first 24 hours. The start of viral symptoms (runny nose, cough, loose stools) is often delayed. Roseola is the most extreme example. Fever may be the only symptom for 3 to 5 days. Then a rash appears.
Bacterial Infections. A bladder infection is the most common cause of silent fever in girls.
Vaccine Fever. Fever with most vaccines begins within 12 hours. It lasts 2 to 3 days. This is normal and harmless. It means the vaccine is working.
Newborn Fever (Serious). Fever that occurs during the first 3 months of life can be serious. All of these babies need to be seen as soon as possible. The fever may be due to sepsis (a bloodstream infection). Bacterial infections in this age group can get worse quickly. They need rapid treatment.
Meningitis (Very Serious). A bacterial infection of the membrane that covers the spinal cord and brain. The main symptoms are a stiff neck, headache and confusion. Younger children are lethargic or so irritable that they can't be consoled. If not treated early, can suffer brain damage.
Overheated. The fever is usually low grade. Can occur during heat waves or from being overdressed. The temp becomes normal in a few hours after moving to a cooler place. Fever goes away quickly with rest and drinking extra fluids.
Not Due to Teething. Research shows that "getting teeth" does not cause fevers.

Fever and Crying

Fever on its own shouldn't cause much crying.
Frequent crying in a child with fever is caused by pain until proven otherwise.
Hidden causes can be ear infections, kidney infections, sore throats and meningitis.

Normal Temperature Range

Rectal. A reading of 98.6° F (37° C) is just the average rectal temp. A normal low can be 96.8° F (36° C) in the morning. It can change to a high of 100.3° F (37.9° C) late in the day. This is a normal range.

Care Advice for Fever

What You Should Know About Fever:
- Having a fever means your child has a new infection.
- It's most likely caused by a virus.
- You may not know the cause of the fever until other symptoms develop. This may take 24 hours.
- For infants more than 3 months old, most fevers are good for sick children. They help the body fight infection.
- Use the ranges below to help put your child's level of fever into perspective:
- 100° - 102° F (37.8° - 39° C) Low grade fever: helpful, good range. Don't treat.
- 102° - 104° F (39 - 40° C) Average fever: helpful. Treat if causes discomfort.
- Over 104° F (40° C) High fever: causes discomfort, but harmless. Always treat.
- Over 106° F (41.1° C) Very high fever: important to bring it down. Rare to go this high.
- Over 108° F (42.3° C) Dangerous fever: fever itself can be harmful.
Treatment for All Fevers - Extra Fluids:
- Fluids alone can lower the fever. Reason: being well hydrated helps the body give off heat through the skin.
- For shivering (or the chills), give your child a blanket. Make them comfortable.
- Offer your child extra water or other fluids by mouth. Cold fluids are better. Until 6 months old, only give extra formula or breastmilk.
- For all children, dress in 1 layer of light weight clothing, unless shivering. Reason: also helps heat loss from the skin.
- For shivering (or the chills), give your child a blanket. Make them comfortable.
- Caution: if a baby under 1 year has a fever, never overdress or bundle up. Reason: Babies can get over-heated more easily than older children.
Fever Medicine:
- Caution: Do not give a baby under 3 months any fever medicine. Most of these babies will need to be seen.
- For fevers 100°-102° F (37.8° - 39°C), fever meds are not needed. Reason: fevers in this range help the body fight the infection. Fevers turn on the body's imune system. Fevers don't cause any discomfort.
Give an acetaminophen product (such as Tylenol).
Another choice is an ibuprofen product (such as Advil) if over 6 months old.
Goal of treatment: keep the fever at a helpful level. Most often, the fever meds lower the fever by 2° to 3° F (1 - 1. 5° C). They do not bring it down to normal. It takes 1 or 2 hours to see the effect.
Do not use aspirin. Reason: Risk of Reye syndrome, a rare but serious brain disease.
Do not use both acetaminophen and ibuprofen together. Reason: Not needed and a risk of giving too much.
Pain: fever does not cause pain. If your child also has pain, it's from the infection. It may be a sore throat or muscle pain. Treat the pain, if it's more than mild.
Return to Child Care:
- Your child can return to child care after the fever is gone. Your child should feel well enough to join in normal activities.
What to Expect:
- Most fevers with viral illnesses range between 101° and 104° F (38.4° and 40° C).
- They may last for 2 or 3 days.
- They are not harmful.
Call Your Doctor If:
- Your child looks or acts very sick
- Any serious symptoms occur such as trouble breathing
- Fever goes above 104° F (40° C)
- Any fever occurs if less than 12 weeks old
- Fever without other symptoms lasts more than 24 hours
- Fever lasts more than 3 days (72 hours)
- You think your child needs to be seen
- Your child becomes worse

And remember, contact your doctor if your child develops any of the 'Call Your Doctor' symptoms.

How to take your baby's temperature

A normal temperature in babies and children is about 36.4C, but this can vary slightly. A high temperature or fever is usually considered to be a temperature of 38C or above.

Your baby may have a high temperature if they:

feel hotter than usual to touch on their forehead, back or stomach
feel sweaty or clammy
have flushed cheeks

If you think your baby has a high temperature, it's best to check their temperature with a thermometer. This can help you work out whether you need to get medical advice.

Ideally, you need a digital thermometer to get a fast, accurate reading.

You can buy these online or from pharmacies and most large supermarkets.

To take your child's temperature:

Hold them comfortably on your knee and put the thermometer in their armpit – always use the thermometer in the armpit with children under 5 years.
Gently, but firmly, hold their arm against their body to keep the thermometer in place for however long it says in the manufacturer's instructions – usually about 15 seconds. Some digital thermometers beep when they're ready.
The display on the thermometer will then show your child's temperature.

How can I make sure the reading is accurate?

If you use a digital thermometer in your child's armpit and follow the manufacturer's instructions carefully, you should get an accurate reading.

There are a few things that can slightly alter the reading – for example, if your child has been:

wrapped up tightly in a blanket
in a very warm room
very active
cuddling a hot water bottle
wearing a lot of clothes
having a bath

If this is the case, allow them to cool down for a few minutes, but do not let them get cold or shivery, then take their temperature again to see if there's any change.

Other types of thermometer

You can buy other types of thermometer, but they may not be as accurate as a digital thermometer for taking a baby or young child's temperature:

ear (tympanic) thermometers – these allow you to take a temperature reading from the ear and are quick but expensive; they can give misleading readings if you do not put them in the ear correctly, which is more likely to happen with babies because their ear holes are so small
strip-type thermometers – these are held against the forehead and are not an accurate way of taking a temperature. They show the temperature of the skin, rather than the body

You should never use an old-fashioned glass thermometer containing mercury. These can break, releasing small splinters of glass and highly poisonous mercury. They're no longer used in hospitals and you cannot buy them in shops.

If your child is exposed to mercury, get medical advice immediately.

What causes a high temperature in children?

A high temperature is usually a sign that your child's body is trying to fight an infection.

Some babies and young children get a high temperature after having their vaccinations. This should go away quite quickly by itself. If you're concerned, speak to a health visitor or GP.

What should I do if my baby has a high temperature?

You can usually look after your baby or child at home when they have a high temperature. Make sure you give them plenty of drinks, to avoid dehydration. If you're breastfeeding, offer your baby plenty of feeds.

Always contact a GP or call 111 if:

your child has other signs of illness, such as a rash, as well as a high temperature
your baby's temperature is 38C or higher if they're under 3 months old
your baby's temperature is 39C or higher if they're 3 to 6 months old

If you need to speak to someone outside normal surgery hours, you can call your GP surgery's out-of-hours service (if they have one) or NHS 111.

Temperature in a newborn baby. How to bring down?

When the temperature rises in adults, the algorithm of actions is known. But here we have a newborn baby with a hot forehead - the worries of parents are absolutely understandable: you should be especially courteous with babies. Yes, and such little ones are unable to either say, or show, or make it clear what specifically worries.

In this article, we will figure out what is the normal temperature of a newborn baby and how to measure it correctly, where it comes from and what to do for new moms and dads in general - when to sound the alarm.

What is the normal body temperature of a newborn baby?

The rise in temperature is the main indicator of the functioning of the immune system. And he does not always report the course of an infectious disease! The fact is that the thermoregulation of the body of a newborn is imperfect. It simply reacts to the general temperature of the room in which it is located.

In a child of the first year of life, the body temperature can be 36, and 36.8, and 37, and 37.5. And that's okay.

If the temperature in the room is above 25 degrees, the baby's body temperature can rise to 37. For the generally accepted 36.6 in the room where the small child is, it should not be higher than 22-23 degrees, and the baby should not be very warmly dressed.

What to do when a newborn has a temperature?

The very first thing is to undress the baby. Let it lie quietly for 15 minutes and measure the temperature again.

An increase in body temperature in a newborn baby up to 3 months is a reason to call a pediatrician ALWAYS.

From 3 months it is reasonable to assess the situation as a whole - look at the general condition of the baby. What can they be?

If the temperature is about 37 degrees, the child is cheerful and active, eats well, without unnecessary whims, then it is worth keeping calm.
If, even at a normal body temperature of 36.8-37, the child is apathetic, refuses to eat and is naughty a lot, or vice versa - he constantly sleeps - it is definitely worth calling a pediatrician. As well as when rising above 38-38.5, even without the slightest cold symptoms (runny nose, cough), or rash (by the way, we already wrote how to treat prickly heat). It is better to do this without delay - within the first two days!
Pay attention to the trembling of the limbs in the baby (febrile convulsions), or the rolling of the eyes at a temperature of 37.5-37.8! This is also a signal for an immediate call to the doctor.
If the temperature of a newborn child has risen, you take certain actions: for example, physical methods of cooling (undressing, airing the room) or giving antipyretics, but within 3-4 hours the temperature does not subside. Call the pediatrician!
Maintaining an even temperature, for example, 37.5, but for more than 5 days is another reason to consult a doctor.
Fever above 38-39 degrees. And she always has a reason. There are 2 types of fever: white and red type.

Consider the type of fever

White type - hot forehead, but cold hands and feet with a marble tint. Plus there may be chills. This is the reaction of the nervous system and blood vessels to intoxication. In this situation, it is worth giving an antipyretic, and simply rubbing the arms and legs (massage) - to restore blood supply, relieve spasm from small vessels, due to which the limbs turn pale or turn blue.
Red type - the child is all hot, wet from sweating. It is worth giving an antipyretic, wiping the baby with water, increasing heat transfer - offering more liquid.

!!! Children up to a year old cannot be rubbed with vinegar or alcohol solution, it is dangerous.

How to measure the temperature of a newborn baby?

The most famous thermometers are mercury and electronic. For all their convenience for kids, electronic thermometers are not very reliable.

A modern and safe analogue of a mercury thermometer - Galinstan. It looks the same, but instead of mercury, a mixture of liquid metals, harmless to humans. They are sold in pharmacies and you probably already have one at home. So Galinstan's thermometers, like mercury ones, are more accurate.

The common practice of measuring body temperature under the armpit is quite revealing. It is better to measure alternately in two armpits and in dynamics. A single measurement does not provide reliable information about the state of health of the child!

In our sanatorium there is a special children's health program "healthy baby". It is suitable for the smallest vacationers from the year! Strengthening the immune system at this age is building the basis for a person’s future longevity.

Before you say goodbye, be sure to read how to strengthen your baby's immunity - it will take 2 minutes! May everyone in your family be healthy!

Normal body temperature values for children, measurement of the child's body temperature

It is believed that a healthy child should have a body temperature of 36.6 °C. And its increase over 37 degrees is regarded as a sign of illness. But it is not so.

Body temperature depends on age and measurement area. It can increase after physical exertion, emotional arousal and feeding.

Devices and time for measuring body temperature

To determine the temperature, the following types of thermometers are used:

digital;
mercury;
infrared.

The optimal time for thermometry is 7-9 am and 17-19 pm. As prescribed by the doctor, the determination of the temperature during the day in children can be performed 3-4 times.

What temperature is considered normal for a child?

Immediately after the birth of a newborn, the temperature of his body decreases by 1-2 ° C, then within 24 hours it rises to 36-37 ° C. In the first 3 months of a baby's life, its indicators are unstable and depend on external factors: air temperature in the room, sleep, food intake. Normally, these fluctuations do not exceed 0.6 °C per day. For children of the first year of life, a temperature of 37.7 is the norm.

The average body temperature for a child is 37°C. Usually in the morning - 36.3 ° C, and in the evening it can rise to 37.6 ° C.

In what areas can the temperature of children be taken?

Underarm

The temperature measurement time under the arm is 5-10 minutes and depends on the type of device.

In the rectum

It is used in children under 5 years of age and in debilitated patients. For this method, it is desirable to use medical electronic thermometers with a soft tip. It will take 1-1.5 minutes to determine the rectal temperature.

Oral

The procedure is performed both under the tongue and behind the cheek. Contraindications to the use of this method are: children under 4-5 years of age, increased excitability and impaired nasal breathing. The duration of temperature measurement by the oral method is from 10 seconds to 3 minutes.

In the ear

The temperature in the ear is measured with an infrared sensor. The tip of the thermometer is inserted into the ear canal and the result appears on the display.

Forehead

Forehead temperature can be measured with a contact and non-contact thermometer. It will take 3 to 5 seconds to get the result. If the baby is sleeping or excited, then it is more convenient to use a non-contact method for measuring temperature.

Crotch

Mainly used in infants. The measurement time in the inguinal fold is 5 minutes.
