What is the reason for a 13-month-old baby constantly sticking out their tongue?

Patient's question:

No

Doctor's answer:

Hello, sometimes when the baby is thirsty, they may stick out their tongue. Additionally, when the baby is teething, the itchy and painful gums may also cause them to stick out their tongue. Mom should pay attention to observe. If it is not teething, the baby sticking out their tongue may also be playing. Mom does not need to worry.
