Question
My baby has been drooling a lot every day since they were four and a half months old! Is this normal?
Answer
Drooling starting from four months old in a baby is a form of physiological drooling that usually does not require treatment. As the baby grows and develops, the eruption of teeth and changes in the oral structure will gradually improve the drooling phenomenon. However, if accompanied by symptoms such as cracked corners of the mouth, congestion or ulceration of the oral mucosa, or incomplete intellectual development, it may indicate certain diseases and require timely medical attention.
