Question
What’s up with a nine-month-old baby who frequently licks their tongue?
Answer
If a nine-month-old baby frequently licks their tongue but shows no other symptoms such as refusing to eat, crying, or drooling, this is typically a normal occurrence. After birth, the baby’s nervous system rapidly develops, starting from the center and moving outward. Therefore, the oral nerves in infants develop earlier than the hand nerves. Generally speaking, this behavior disappears after three months. If it persists beyond three months, it may be due to a lack of vitamins and requires a medical examination.
