My suggestion is to slowly ween her of the bottle. Allow an extra 30 minutes between bottle feeding at night for one week and then add 15 minutes each week there after. This has worked for me. During the day make her a full meal and give her a cup of milk with a straw. The straw will mimic the bottle without having her lye down. Having her eat all, or most, of her food will get her full. Once she gets use to eating more solid foods she won't drink as much during the day.
Weening a child from the bottle, your bed and other things are very difficult, I know I have been there. There were many night when I would but my children to bed without an bottle and ran out the room and shut the door behind me crying, because I wanted to give in so very badly. If it wasn't for the support of my husband, I don't think that I could have done it.
Hank in there it will get easier!!!!!
