My one week old daughter has decided in the last few days that she needs to bite/clampdown when initially latched - but just on one side. Things are going great on the left side, but whenever I latch her onto the right she just clamps down (just with the first few sucks). I've tried several different positions, relatching, and trying to hold her chin down but nothing has seemed to help. Luckily, she doesn't do it for the whole feeding, but what she is doing is making me really sore on that side. She doesn't have a tight frenulum, and I'm out of ideas. Anyone have any suggestions?
