Need help weaning

Hi guys! I have a beautiful 11 month old baby girl who nurses for comfort and to sleep. I have two issues right now, I'm ready to wean because she had started to bite me alot. She has 3 teeth! I've always had to supplement for her, because of lack of supply. So I need tips on that. Literally my husband can't even get her to sleep without driving in the car. 2nd part, we co-sleep. I'm ready for my bed and my husband again. Love her so close to me, but need to be able to fully sleep again. Help me!!!!!!
