My LO is 4 weeks old, EBF. Sometimes when she nurses on my right breast, she gets a good latch, the pulls her head back and "pops" my nipple out of her mouth. It hurts like crazy when she does this and she will do it repeatedly. I've tried letting her begin by nursing on the left breast first (she has only done this a couple times on the left side), to ensure she's less excited/irritated by the time she begins to nurse on the right. I'm not sure how much this helps, as the behavior isn't every time she nurses. Is this normal behavior? How do I discourage her from "popping" my nipple out of her mouth. I'm worried she is going to injure my breast.
