The normal body temperature of a baby usually lies between 36 to 37 degrees Celsius, which may vary slightly. Any other changes in the temperature range may result in a fever or hypothermia. The temperature of the bodies of children varies due to their activity levels, nutrient consumption and various other causes. Your baby might be suffering from fever if the body temperature goes above 37.5 degree Celsius or 99.5 degrees F. And if the body temperature dips below 35 degrees C, then this causes a sickness known as Hypothermia.

It is a great way of keeping your baby warm in summer when the AC is on and also in winters when the temperatures are low outside. Use hot packs, chemical heating pads on the chest, neck, back and other areas of the body is recommended. However, make sure you do not keep your baby swaddled up beyond 4 to 5 months of age. If your baby is more than 6 months old, give them a warm drink.

A digital thermometer is a good option for maintaining your baby’s temperature. You may measure your baby’s temperature before and after taking a bath or when you expose your baby to an air-conditioned environment.

When Should I take My Child and Visit a Doctor?

A low body temperature is not good for your baby; however, if your baby’s temperature drops below 32 degrees, this could mean severe hypothermia and requires immediate medical attention. As soon as you register such low temperature in your baby, you should get in touch with your doctor, and your baby will be given emergency care. This may cause life-threatening complications, organ failure and other fatal difficulties in babies.

No matter whether you register baby temperature low at night or anytime during the day, you must seek medical help. This is because sometimes the temperature measured from the armpit may not be accurate and rectal temperature may need to be taken, which is best done under medical supervision at a hospital.


Though sometimes certain preventive measures may work, however, it is suggested that when it comes to babies, always seek your doctor’s advice. Timely medical intervention may save your baby from various life-threatening conditions.
