My dd2 will be two on Friday. Recently we've developed some problems with latch. She's holding onto my nipple by biting and frequently pulling away while still latched on. I'm starting to think about weaning, to be honest, because it really kinda hurts. I've tried talking to her about good latch, but it isn't really helping. She also has decided to only nurse from one breast. Any advice? Do lactation consultants work with toddlers?
