I give my son a little bit of water in a bottle. Its a little bit cool on his gums and he can chew on the nipple, i also give him Tylenol and baby teething gel. And some times i try a pacifier and he'll chew on that.
Hylands dissolving tablets. You can get them from Target. They're homeopathic too
I give my daughter Tylenol and I have a variety of teethers( squishy, hard, textured, soft, edible, and cold) half the time shell just chew on a stuffed animal or blanket because she prefers them.
Cold wash cloths, teethers, Advil/Tylenol, massage their gums with your finger
