My 4 month old is teething and she keeps gumming down into my nipples! She has caused some damage on them which I use lanolin on but is there anything else I can do? I have tried unlatching when she does that but it doesn't do much. My older daughter never did that when she  was getting her teeth in. If she is causing nipple damage now without teeth, I am seriously scared about what she is going to do when she gets her teeth in!! 😥😥
