Good morning Dr. my son is 4 months and 15 days old. he started drooling alot what should I do for that

A. hi it is sign of teething. you can rub your pointer finger on sore gums of your child. or you can use damp wet clean Cotton clothe for this . keep your child mouth area clean I would suggest to use Babyhug wipes for this which will help to prevent drooling rashes.
