What should I do if my baby is drooling excessively?

There are many reasons why babies drool. For example, their salivary glands mature and become more active. Poor swallowing reflexes are another common cause of drooling in infants. Additional factors—such as teething and oral stimulation—can also contribute to excessive drooling in children. So, what should you do if your baby is drooling excessively?

What to Do If Your Baby Is Drooling Excessively

Managing severe drooling requires careful analysis based on the child’s age and individual circumstances. In infants aged one month and older, especially those between three months and three years, most drooling is physiological—that is, entirely normal. Around three to four months of age, salivary glands begin maturing gradually, leading to increased saliva production. Moreover, young infants have relatively shallow oral mucosa, smaller oral capacity, and underdeveloped chewing ability, making it difficult for them to manage the increased volume of saliva—hence frequent drooling.

As babies grow, the eruption of teeth increases oral capacity, and they gradually learn to chew and swallow effectively—resulting in a natural decrease in physiological drooling. Therefore, older children—typically those over three years of age—usually do not drool excessively. However, some children may experience pathological drooling due to underlying medical conditions. These may include oral problems such as stomatitis or gingivitis; respiratory or viral infections; neurological disorders—for instance, facial nerve dysfunction—or developmental delays that impair regulation of saliva production and swallowing.

It is recommended to ensure adequate sleep, avoid staying up late, engage in appropriate physical activity and exercise, maintain a healthy weight, and follow a low-salt, low-fat diet to help stabilize blood pressure. We hope this information is helpful to you.
