However, so much saliva is almost completely swallowed by us unconsciously, so there is no saliva flowing out. Newborn babies have very little saliva because the functions of their central nervous system and salivary glands have not yet matured. Saliva secretion gradually increases by 3 months, and some babies with strong secretion ability will drool. At 6 to 7 months, the baby\’s deciduous teeth will erupt, stimulating the trigeminal nerve will also increase saliva secretion. In addition, the baby\’s mouth is the smallest, the floor of the mouth is shallow, and the baby cannot control the saliva in the mouth. If he does not swallow in time and accumulates, he will It flows out naturally. Saliva secretion is also controlled by nerves. Babies may also have poor ability to inhibit saliva secretion and poor swallowing function due to their immature brain development, resulting in frequent drooling. After the baby is 1 year old, as the brain develops, salivation and defecation occur less frequently. By the time the baby is 2 to 3 years old, his swallowing function and central nervous system have further improved, and drooling is generally no longer possible. If your baby continues to drool as he grows up, it may be abnormal. This may be due to poor neurological or endocrine development, inflammation in the mouth, indigestion, etc. Further examination is required.

When saliva flows outward onto the skin, it can easily corrode the outermost stratum corneum of the skin, causing skin inflammation and triggering pediatric skin diseases such as eczema. Home treatment for a three-month-old baby drooling: Wipe off the baby\’s saliva at any time. Do not use force when wiping. Just wipe the saliva dry gently to avoid damaging the local skin. Wash the skin where saliva has touched with warm water, and then apply oil to protect the skin. It is best to wear a bib around your baby to prevent saliva from staining clothes.
