DS is 9 months and I've been lucky to never have a problem with breastfeeding until now. His two front top and bottom teeth are coming through and he's taken to chomping down on my nipple. The teeth aren't even all the way out and already it's pretty painful! I've tried unlatching with a stern "no" but he thinks it's a game and smiles and coos winningly at me. Anyone experienced this, and if so how did you get baby to stop it? I really want to keep breastfeeding as we both love it.
