Baby biting down on boob

Alex • AZ🌵 Married, momma of 2 ❤️

Ladies, my 3 1/2 month old daughter has started to bite down on my nipple, she doesn’t have teeth yet but it still hurts! She’s been drooling a lot and can’t keep her hands out of her mouth, could it be teething? How do I teach her to not bite my nipples 😖
