I have a bf son his 10 mts old with 7 teeth a lot for his age. I'm still breast feeding. I bf my first son until he was a year. He didn't hurt me when nursing. DS#2 I don't think is bitting, but he's killing me. I thought they couldn't bite when eating. He seems to be latched correctly and he's eating. He will not take juice, milk or water from a sippy cup for me. I've tried many different kinds. My son eats really well and will try all kinds of food. But is not open to taking liquid any other way. Sometimes the sitter can get him to do so. Please help? Not sure how much longer I can nurse him the pain is horriable. But he needs liquid and it's 100 degress where I live.
