My baby is almost 6 weeks old, and has been breastfeeding beautifully. However, in the last two weeks she has been popping my nipple in her mouth starting halfway through the nurse. It feels like she is trying to bite, though she has no teeth yet. I've been trying techniques recommended for biting, but she has isn't really responding to them. I'm not sure why she is doing this, or how to get her to stop.
Any suggestions would be appreciated!
