The drooling you see in the newborn period is nothing compared to the flood you will get when your child starts teething. Drooling is simply a normal body function in infants as they cannot or dont want to swallow all of their saliva. This is made worse by teething which greatly increases the amount of saliva they produce. The drool is slightly toxic to the skin, though, and can cause rashes around the mouth, in the neck folds and on the chest. To prevent this kind of rash, use Vaseline and PLASTIC BACKED bibs as barriers. To treat the rash, use over the counter hydrocortisone cream (Cortaid) sparingly anywhere except close to the mouth (as they could swallow some) and / or a good moisturizer (see dry skin section).
