I have a 19 month old who has suddenly developed a problem with his latch. He's not biting down on purpose but somehow he keeps getting my nipples with his teeth. At first I thought it was a fluke and just used lots of lanolin and gritted my teeth waiting for them to heal but then it got worse and now I have huge, painful gashes on each side. I've tried to get him to say "ahhh" and open his mouth wide before letting him latch and using my fingers to prevent him from clamping down prematurely but that just makes him more desperate and seems to have made things worse. Nursing is excruciating and pumping isn't much better. I bleed every time. I'd planned on nursing him until he was 2 (or until he'd self-weaned) but I think I might need to be done now. I feel terrible because he is starting to get sick and wants to nurse for comfort but I really don't think I can go on like this. Any suggestions/advice?
