Any sugggestions on how to get baby to not bite? He has had 2 bottom teeth for 2 months now and only bit down a few times but now he is biting down almost every time he nurses. He is getting his top 2 teeth right now...they are just breaking through so I thought maybe that is why he is biting now but with more teeth coming...I'm scared! I have startled him a few times by yelling ouch! but he is still doing it. He is 7 months and I'm afraid to keep nursing It hurts!
