Why is my four-month-old baby drooling?

When a baby is just born, he is full of curiosity about the world, and his little head is always looking here and there. Babies don't know anything at this time and can't communicate with adults. Parents must patiently let the babies learn something. Some babies spit up milk, and some babies are still spitting when they are four months old. Now the editor will take a look with parents and friends to see why babies drool at four months old.

A four-month-old baby is about to grow milk teeth, and it is normal for him to start drooling. The baby's swallowing function is not yet perfect. At this time, the baby is curious about many things, and his first reaction when he gets something is to put it in his mouth. He wants to know the taste of each thing. As for babies sucking their fingers, I looked up information when my baby was young, which said that sucking their fingers can train his brain and behavior to achieve a unity, so don't stop it, just pay attention to cleaning the baby's hands.

About 3-4 months after the baby is born, the baby's central nervous system and saliva secretion gradually increase, but the swallowing function is still not perfect, so the baby often drools, which is called physiological drooling. Pay attention to whether there are canker sores or ulcers in the mouth, which can also stimulate drooling. Wipe it off with a soft cotton cloth in time to prevent prolonged irritation and redness of the skin.

The regulation of saliva secretion relies on two aspects: one is local stimulation in the oral cavity; the other is the reflex of the nerve center. Newborns produce very little saliva because their central nervous system and salivary glands are not yet fully developed. By March, saliva secretion gradually increases, and some babies have a stronger secretion ability and will drool. When the baby is 6 to 7 months old, the baby's deciduous teeth erupt, which stimulates the trigeminal nerve and increases saliva secretion. In addition, the child's oral cavity has a small capacity and cannot swallow or regulate the saliva in the mouth, so the saliva will flow out naturally after accumulation. Saliva secretion is also controlled by nerves. Young children may drool frequently because their brain development is not yet complete, and their ability to inhibit saliva secretion and swallowing function are slightly poor.

After reading the above introduction, parents don’t need to worry about this phenomenon of their babies. It is normal for a four-month-old baby to drool, and this phenomenon will disappear in one or two months. However, when taking care of a baby, the mother must wipe the baby's saliva in time. You can use a bellyband so that the baby's clothes will not get dirty.
