My baby got her first 2 bottom teeth at 4 1/2 months old. Tylenol and hylands teething tablets are great!!! My baby didn't care for the teething rings, but she LOVED it when I gave her a wet washcloth to chew on. Try that and see if it works. Good luck! It'll only be a few days hopefully before this is all over and then he'll have some new pearly whites!
