I LOVE your posts @breastfeedingmom ! They're so perfectly precise and correct, easy to read and relatable.
I was worried about my LO breastfeeding once he had teeth, but there has only been a few occasions where he has felt the need to bite and that was like you said, when he was coming to the end of a feeding and starting to release the latch, as a sort of 'play around'.
The pain does make you jump however, I agree, it's hard to control your reaction, but is also very important to stay composed so baby doesn't think it is some kind of game! Upvoted!
