Dd4 has been causing an incredible amount of pain when breastfeeding. I am really not sure what it is, but I think she is rubbing my nipple against her teeth. I feel like I am an 'experienced' breast feeder. I've feed all 4 dds to 10, 11 and 16 months, stopping only to get pregnant again or when I was pregnant and breastfeeding really hurt. They have all had teeth very early also, and I haven't had problem with teeth, apart from biting. I usually take them off the breast instantly, tell them no, and eventually they get the message. She breastfeeding to sleep generally, and she is taking a along time on the breast to get to sleep, also wakes frequently throughout the night, it is making breastfeeding a terrible experience. This is my last dd, and I really wanted to keep feeding, but at this point I was just going to feed til she was one and then stop. Has this happened to anyone? Any suggestions?
