What is the reason why a three-month-old baby spits up?

When babies are young, their language expression ability is not strong. They cannot express or cannot express clearly when they are uncomfortable or sick. They can only cry. It all depends on adults to pay more attention to them and pay attention to the reasons for their crying. If adults are careless, babies will suffer. Here are some reasons why three-month-old babies spit up, I hope it will be helpful to you.

Physiological salivation

(1) For most children, breast milk is their main food for the first 4 to 6 months after birth. Children in this period have no teeth in their mouths, short and wide tongues, thick fat layers on their cheeks, well-developed facial muscles, and thickened and protruding jaw mucosa. These structural features are very helpful for grasping the nipple and coordinating the sucking action while feeding. At this time, the salivary glands do not function well and the amount of saliva secreted is small. After 4-6 months, breastfeeding alone can no longer meet the needs of children's growth and development, and complementary foods are added. Food has a strong stimulation on the nerves and salivary glands, which enhances the secretion function of the salivary glands and significantly increases saliva.

(2) Eruption of deciduous teeth When deciduous teeth erupt, they will produce mechanical stimulation to the sensory nerves of the gums, causing the salivary glands to secrete more saliva. However, at this time, the child's oral cavity is shallow and the swallowing reflex is not sensitive. The child cannot swallow the excess saliva in time, causing saliva to accumulate in the mouth and overflow. As the deciduous teeth erupt, the amount of saliva secretion will gradually return to normal. At the same time, the dental process will gradually form, the palate will slowly rise, and the bottom of the mouth will gradually deepen to accommodate more saliva. In addition, the swallowing movement will gradually be trained to mature, so that the saliva can be swallowed in time, and the drooling will stop naturally.

Pathological salivation

(1) Breastfeeding for too long Some mothers mistakenly believe that the longer the breastfeeding period, the better, and extend breastfeeding to after the age of one, or even add complementary foods after weaning. This practice is not conducive to the normal development of children's spleen and stomach. Traditional Chinese medicine believes that saliva is the fluid of the spleen. When the spleen and stomach are weak and out of regulation, drooling occurs, which is often accompanied by indigestion.

(2) Mechanical injury to the parotid gland. Some parents and relatives often pinch their children's cheeks out of love. This practice can easily cause mechanical injury to the parotid gland, resulting in saliva secretion much greater than that of normal children, thus causing drooling.

(3) Oral inflammation Many oral inflammations, such as catarrhal stomatitis, bacterial stomatitis, and stomatitis caused by herpes virus, can stimulate the salivary glands to secrete more vigorously and cause drooling. At this time, the saliva that flows out is mostly yellow or bloody, with a foul odor, and is often accompanied by symptoms such as fever, irritability, and refusal to eat.

The above is an analysis of the reasons why three-month-old babies spit up. It can be seen that it may be a normal phenomenon or it may be a disease. In short, if you are not sure, it is best to see a doctor. Generally speaking, if a baby is sick, he or she should be taken to the doctor in time to prevent the condition from getting worse. There are also some situations where it is not necessary. For example, if your baby has a fever and the temperature is below 38 degrees, you can take physical measures to reduce the temperature. If the temperature can be lowered, there is no need to see a doctor. You should not go to the hospital as soon as the fever is slightly high. It is not good to go back and forth.
