Why does my baby drool while sleeping? There are two reasons why babies drool while sleeping: physiological drooling and pathological drooling.

1. Physiological salivation

1. Babies drool while sleeping, which often occurs during the teething period. At this time, the oral cavity is an important organ for the baby to change. The increased saliva can reduce the gum pain caused by the growth of deciduous teeth. It is normal to drool at this time. Mothers do not need to worry too much. Just pay attention to oral hygiene. As the baby grows up, the drooling phenomenon will gradually disappear.

2. The salivary glands of newborns are underdeveloped, saliva secretion is small, and there is basically no drooling. As the baby grows older, when he is four or five months old, the trigeminal nerve is stimulated by complementary food, saliva secretion increases, and the baby's oral control ability is not strong, which will cause drooling. Mothers don’t need to worry. As the baby grows, his swallowing ability improves and the drooling phenomenon will generally disappear by around three years old.

2. Pathological causes

It mainly refers to the baby drooling due to certain diseases, such as oral ulcers, mucosal inflammation, cretinism caused by neurological diseases, mental retardation and other problems. At this time, mothers should pay attention and not delay the disease, and take the baby to the doctor for treatment in time.

Ways to prevent your baby from drooling while sleeping:

1. Make sure your baby sleeps in the correct position

If a baby drools while sleeping, it may be caused by the baby's incorrect sleeping posture. For example, sleeping on his stomach or on his side may cause the baby to drool while sleeping, so mothers should adjust the baby's sleeping posture to prevent the baby from drooling.

2. Pay attention to your baby's oral inflammation

Babies drooling while sleeping may also be due to pathological reasons, such as an oral infection that causes bacteria to grow and trigger inflammation, making the baby's mouth painful and prone to drooling. At this time, the mother can give the baby some anti-inflammatory drugs to make the oral ulcers heal slowly, and the phenomenon of drooling while sleeping will gradually disappear.

3. Prevent baby’s teeth from deforming

If a baby has deformed teeth, especially if the front and back teeth are very obviously uneven, then the teeth will be exposed when the baby opens his mouth, and he will not be able to close his mouth when sleeping, which will make the baby more likely to drool. In this case, the mother should take the baby to have orthodontic surgery as soon as possible.

4. Prevent neurological diseases

If the baby suffers from systemic neurological diseases, such as autonomic nervous system disorders and neurosis, the baby may drool while sleeping. Because this type of disease can cause the baby's nerves to become abnormally excited, causing the brain to give incorrect instructions and increase the secretion of saliva.

The above is an introduction to why babies drool while sleeping. I believe that after reading the above introduction, you already know why babies drool while sleeping. Generally speaking, it is normal for babies to drool while sleeping, so parents don’t need to worry too much. If your baby is several years old and still drools while sleeping, you should pay attention to it, as it may be caused by a disease!
