Dd is 12 Weeks old...we bf fine but in the last few days she has started clamping down or biting before she ends the feed. She's never done this before and I want to stop her before it becomes a habit but don't knew how. Its quite uncomfortable but i'm worrying that if she keeps it up I'll be forced to stop once she gets teeth. I've read taking then off when they bite etc but she's ready to come off by then anyway so she probably wouldn't notice! Help please! ,
