Why do babies stick out their tongues

Patient's question:

Hello expert
My baby is three months old today. Recently, he has been fond of sticking out his tongue and licking his clothes. What could be the reason? Urgently looking forward to your reply

Doctor's answer:

Babies sticking out their tongues is generally a normal phenomenon. Babies usually start producing saliva from their salivary glands after two months, and at this time, if they use their tongues to lick, they may stick out their tongues.
Recommendation: If the baby also has symptoms such as constipation, poor appetite, or lack of activity, it is recommended to see a pediatrician. Additionally, if the baby still exhibits this behavior as they grow older, proper guidance should be provided to avoid it becoming a habit.
