I breastfed my baby until he was 3 months old and he randomly stopped so I had to pump for 2 months and then he started nursing again for a couple of weeks. But now he refuses to nurse again! What the heck is going on with him? Could it be because of his teeth again? I'm not going to pump for that long again. He'll be switched to formula by 7 months if he doesn't start again soon and I hate it
