LO is now 8 months old. She is biting me - I say "NO!" and take her off the breast, but she just sits there and laughs about it. This morning, she bit and left teeth marks in my nipple. I took her off and completely skipped her morning feeding because I know she's just going to bite again and again. I'm in so much pain, I feel like I should just wean her - I feel like crying, please help!!!
