My 9 month old DD is teething with her 3rd and 4th teeth having broken the gum over the last few days.

For the last 48 hours she's been biting me when I feed her. It's excruciating when she does it, and the first two times she did it I let out involuntary yelps and now she thinks it's a game.

She only does it in the afternoons/evenings when my supply is at it's lowest, but then she gives me a cheeky grin and a giggle.

Right now I'm taking her off, covering the nipple with my hand, giving her a stern look and then looking away. I wait a minute or so and then allow her access again. Is this the right thing to do? Clearly crying out wasn't! I have a low milk supply and I'm nervous that all this on and off messing around will make it even worse, but I can't let her continue to bite, it's too painful! Is this likely to continue for a while? I feel like I'm lurching from one bf problem to another at the moment!
