What is the problem of newborn drooling frequently?

In the process of caring for newborns, parents should pay attention to some of the symptoms they show. They are harmed by some diseases, so only by discovering them in time can we minimize the adverse effects as much as possible. What I want to introduce below are some reasons and common sense about the frequent drooling of newborns. I hope that parents have a scientific understanding of these reasons and common sense.

Why do babies drool?

It wasn't the kind of drooling that ordinary children do, this was a lot of drooling, and the mask around his neck became wet in a short while.

Generally speaking, babies drooling is a temporary phenomenon and has certain regularity. The baby's salivary glands are underdeveloped in the neonatal period. In the first week after birth, the saliva secretion is about 50-80ml per day, which is 1/20-1/25 of that of an adult. The amount of saliva secretion of infants only increases to 200-240ml per day and night at about 4 months, and only increases significantly after 5 months.

0-3 months: less saliva

Newborn babies do not drool because their salivary glands are underdeveloped and secrete less saliva. In addition, most babies at this time are breast-fed or fed with milk, so they do not need salivary enzymes to participate in digestion, nor will it stimulate salivary gland secretion.

4-6 months: Starts drooling

Adding starchy foods such as rice noodles to the baby will reflexively stimulate the secretion of the salivary glands. When the baby is 5-6 months old, the saliva secretion will increase significantly. However, the baby's oral cavity volume is relatively small, and the swallowing regulation function is not yet fully developed. The baby cannot swallow the saliva secreted in time, so saliva will flow out.

7-18 months: Drooling

The period when drooling is most frequent is during the baby's teething period. When deciduous teeth erupt, they push out of the gums, causing mild swelling and discomfort in the gum tissue, stimulating the nerves on the gums, and also stimulating the salivary glands to reflexively increase secretion.

The above is an introduction to some common sense issues regarding drooling in newborns. I hope that parents can treat this situation scientifically when they find it, because sometimes it is a normal phenomenon and will gradually ease as the child grows up. Sometimes it is really a sign of teething in children, so we should pay attention to these contents.
