Drooling in children can be physiological or pathological. The vast majority are physiological findings. When children are born soon, salivary gland cells are not yet developed, saliva secretion is very little, to four or five months later, children began to eat supplementary food, increased chewing. At the same time, the milk teeth also begin to erupt, the gums are stimulated, causing neural reflexes. All these will stimulate saliva secretion and make more saliva. However, children’s mouth is shallow, and will not swallow the excess saliva in time, too much saliva will flow out along the corners of the mouth. This is a normal physiological phenomenon and does not require treatment. After the age of two and a half, the mouth full of milk teeth, the phenomenon of drooling will improve. However, the same period of teething, why some children do not drool? This is because it is a physiological phenomenon that does not always react the same way in each individual. But some children drooling is a pathological phenomenon, such as having stomatitis, including tongue infection and gingivitis. In this case, the drool is yellow or reddish in color and has a foul odor. The child may also have a slight fever, be reluctant to eat, and be irritable. In this case, you should consult a doctor. In addition, if the child has often chewed hands or chewed rubber nipples and other bad habits, will also make the mouth irritated, forming drooling. For drooling children, pay attention to local cleanliness, wipe drool with a clean, soft towel, and move gently, put a soft cloth bib around the child, change it often, and keep it dry. If there are ulcers, use boric acid water to wash, apply some astringent ointment, like zinc oxide oil, tannic acid ointment, etc. . Drooling is a process. . Newborn babies are not drooling because their salivary glands are not developed and secrete less saliva, so there is no extra saliva coming out of the baby’s mouth; plus at this time the baby’s main food is milk or liquid food, which does not stimulate the salivary glands much. The baby teething period is the most frequent period of drooling, when the milk teeth erupt, small teeth out of the gums to grow outward, will cause mild swelling and discomfort of the gum tissue, stimulate the nerves on the gums, salivary glands reflexively increase secretion. With the growth and development of the baby, the faster developing children will stop drooling at one and a half years old, and most children will also gradually and effectively control the swallowing action because of the maturity of muscle motor function before the age of two, and the sides of the mouth will no longer be wet. 1, to wipe away his saliva at any time, do not force when wiping, gently wipe the saliva dry to avoid damage to the local skin. 2, commonly used warm water to wash the drool everywhere, and then coated with grease to protect the skin of the chin and neck. It is best to put a bib around the child to prevent drool from soiling clothes. 3, to wipe baby drool handkerchief, require a soft texture, to cotton texture is appropriate, to wash and iron often. 4, if the baby drooling is particularly serious, we must go to the hospital to check to see if there are any abnormal diseases in the baby’s mouth, swallowing function is normal, etc..
