My son is 3 months old and we nurse wonderfully! Yesterday and today though I noticed a little but of pain on my nipple during nursing. I was playing goo goo ga ga with him later (just a silly made up game of course) and I felt in his mouth what I think are teeth,well the start of them on his bottom gums. I can see a little white also. Tonight while I nursed him before bed I felt what I'm sure are his teeth on my nipple. The pain was in the same spot as the little toothies. So I'm thinking he's giving me a little bite. It doesn't really hurt,but I do feel it. What am I supposed to do?
