My DS is 4 months old right now, and I really would like to nurse him until he self weans. My question is regarding biting though. He already bites, and he doesn't have teeth! It doesn't really hurt right now, but I know it will once he starts having teeth. Is there a way to stop him from biting now? He's only 4 months old- so I'm not sure how to go about it?? Any help would be great!
