1-year-old baby’s body temperature of 35.5 degrees is not normal. The normal body temperature of children is 36.5 degrees – 37.5 degrees of anal temperature, which is normal; axillary temperature of 36 degrees – 37 degrees is normal; oral temperature is generally 0.2 degrees – 0.5 degrees higher than the axillary temperature. Body temperature less than 35 degrees, known as the temperature does not rise. If the baby’s body temperature is 35.5 degrees, the baby is in good spirits, consider whether it is caused by too little clothing, low ambient temperature, sweating, etc. You can increase clothing, drink warm water, raise the ambient temperature, and retest the body temperature after half an hour to one hour. If the temperature is above 36 degrees, you can continue to observe; if the temperature is still lower than 36 degrees, you should take your baby to the hospital for consultation.
