My little girl didn't have any teeth until 13 months, so I managed to get through a fair bit with no major dramas.
She's now 16 months, and yesterday bit BOTH of my nipples when I tried to get her off. She uses it as a way to keep feeding, and I now have 2 raw little teeth HOLES in my nipples, ouch!
I think the idea of taking him off when he bites and not letting him finish the feed is a good one, provided you can get him off without taking the nipple with him!
Other than that I don't really have any ideas. I also found that yelling out only makes her bite harder.
Hopefully it will pass if you can keep in there.
Good luck! smile
