Baby temperature 36.3 ℃ normal, to the baby temperature measurement has the following three methods: 1, armpit thermometry, the normal temperature range is 36-37 ℃. 2, oral thermometry, the normal temperature range is 36.2-37 ℃. 3, rectal thermometry, the normal body temperature range is 36.5-37.5 ℃. So no matter which thermometry method, the baby’s temperature 36.3 ℃ is normal. If the baby’s body temperature is lower than the normal value range, is hypothermia, the baby’s body temperature is too low with the environmental factors, if the environmental temperature is too low, the warmth measures are not done, there will be hypothermia phenomenon, or the baby takes antipyretic medicine after the fever a lot of sweating, resulting in hypothermia. If the baby’s body temperature is higher than the normal value range is fever, caused by many reasons, common bacterial, viral infections, indigestion, food accumulation can also cause the baby fever, sometimes shock can also lead to fever.
