Haven't had problems with painful latch since dd was a few days/weeks old. Suddenly feeding is agony. When she comes off there are teeth marks on my boob. This has never happened before. What's going on? Is it teething? She has 8 teeth and her teething has never caused me pain in the past. Any ideas what's going on? She recently dropped a couple of feeds so we're now down to first thing, before nap and before bed. Would that make a difference? Can't see how? Help. Ow.
