Patient's question:
Detailed medical condition and consultation purpose: The child is three months old. Recently, they have been constantly sticking their tongue out. At first, they would put saliva on their lips to play with it. In the past few days, they have been sticking their tongue out more frequently and continuously. The elders say it's not good, but I don't know what the problem is. Is it normal?Doctor's answer:
?Hello, if there are no other issues such as refusing to nurse, being fussy, or drooling, then this is a normal phenomenon. After a baby is born, their nervous system begins to develop rapidly. The order of neural development in babies starts from the center and moves outward to the periphery. Therefore, the nerves around the baby's mouth develop earlier than those in their hands. For babies aged 1 to 5 months, the mouth is a tool for exploring the world, as they use it to explore and experience their surroundings. So, they may stick out their tongues and lick everything they touch—this is part of their learning process.
