My DD is 10 months old and we've had a great nursing relationship from day 1. For about the past week, though, she seems to be nursing differently on one side. I can't quite put my finger on it, but it seems like she's grazing the nipple with her teeth a little. She's had teeth for a while now and this hasn't happened before. It's uncomfortable when she does it, and that side's getting a bit sore. I've tried breaking the latch and starting over, and sometimes it helps, but usually she goes back to it after a minute. I just don't get it....nothing's changed, and I haven't been sore while nursing her, ever. I also nursed my DS for 22 months and while we had a rocky start, I don't think I had any soreness with him after the first few months. Any suggestions? TIA.
