After 4 months, due to the beginning add complementary food, saliva secretion increases, and deciduous teeth begin to sprout after 6 months, which can stimulate the nerve on the gum and make the secretion of the saliva glands increase reflectively. The baby has not yet formed the ability to swallow saliva at this time, too much saliva will flow out of the corner of the mouth involuntarily, that is, the "drooling" used to be, especially for children aged 1 to 2, the drooling phenomenon in this period is a normal physiological phenomenon, and parents don't have to worry about it. Babies with long teeth will drool unconsciously and become "mouth water Emperor". Often, their clothes will be soaked by saliva when they are not careful. At this time, baby bibs is indispensable. Do not use force when wiping the baby's saliva. Gently dry the saliva to avoid damaging local skin. But such frequent wiping is also a physical work. The best way is to use saliva towel.
