Why does my baby drool?
Babies drool because they haven’t yet developed the ability to use their tongue to move saliva, or spittle, to the back of the mouth and swallow it and younger babies do not have any teeth to keep the saliva behind the gums. Instead, it leaks out of the front. This is normal, starting at about one month of age and usually ending at about two years. It is heaviest around six months. If your baby suddenly starts to drool more than usual and is unhappy or has a fever, see your health-care providers. It may be a sign of an infection.
