The baby sleeps restlessly and swallows all the time probably because of indigestion in the body leading to accumulation of food. Because the baby is relatively young, the digestive system is relatively fragile, if parents do not pay attention in the usual feeding of the baby, it will lead to indigestion and food accumulation, usually need to give the baby more easily digestible food, diet is not too cold. As babies usually drool more, at night when they sleep will not spit out, can only swallow to the throat, as the baby grows older, oral function will gradually improve, this situation will slowly get better, most do not need additional treatment. If the baby is breastfed, mothers need to pay attention to the diet, avoiding food with a heavy taste, after the baby has ingested milk, if the taste of milk is heavy may lead to oral thirst, which can cause swallowing as well as sleep quality.
