A low body temperature in a baby is a sign of hypothermia and can be dangerous. Normal body temperature for a baby is about 36.4-37.3°C (97.5-99.1°F). A rectal temperature of less than 36°C (96.8°F) is considered low and should be treated immediately.
Hypothermia in newborns can be caused by various factors such as being in a cold environment, a wet diaper, or a low room temperature. If you suspect your baby is hypothermic, it's important to take immediate action. This may include removing wet clothing, wrapping your baby in a warm blanket, and providing additional heat sources. If the baby's temperature does not improve or if they show signs of other health problems, seek medical attention promptly.
