Reasons why children drool while sleeping

Nowadays, more and more young parents are at a loss when it comes to the birth of their children. As they may not know much about taking care of children, they are also very unfamiliar with some of the symptoms of their children. For example, children drooling while sleeping is a phenomenon that everyone often encounters. So what should they do?

Drooling is medically known as sialorrhea or increased salivation. There are many causes of drooling. Drooling is common in children aged 6 months to 3 years and is mostly normal. It is uncommon for newborns to drool. Because the salivary glands of newborns are underdeveloped and saliva secretion is very little, saliva secretion begins to increase at 3 to 4 months. After 6 months, due to changes in diet, the nerves are stimulated, causing increased saliva secretion, and drooling begins to occur. In addition, babies have shallow mouths and cannot regulate excess liquid in their mouths, so drooling occurs. As they grow older, their teeth erupt, the depth of their mouths increases, and infants and young children gradually learn to control excess saliva by swallowing, and the drooling phenomenon gradually disappears. The above drooling is normal. However, some children drool and cry and are restless, refuse to eat, and cry more severely when eating, or have a fever. At this time, you should carefully check the oral mucosa, i.e. the tip of the tongue, cheeks, and lips for ulcers. Ulcers can cause pain and increased salivation leading to drooling, and should be treated promptly. Some drooling is caused by sequelae of encephalitis, facial nerve paralysis and cretinism, which lead to disorders in regulating saliva secretion and swallowing function. In this case, you should go to the hospital for a clear diagnosis and treatment.

First of all, we have introduced above the phenomenon of children drooling while sleeping. In fact, it is very common for many children to drool while sleeping at night. Some of the main reasons are that the child’s body is relatively weak.
