my baby is about to be 5 months. he split or saliva around his lips. is it normal ?

A. While it's true that drooling is very common for children around 2-3 months old, and typically lasts until a child reaches 12-15 months-s (roughly the same age that teething begins) drooling merely means your baby's salivary glands are starting to fire up after not being needed as much when eating easy-to-digest milk.
