I know many mommies hate this answer...but I swear it works. Your daughter is making a power struggle move (unconsciously, of course). She knows if she cries enough you will give in. IF you let her cry and DONT GO into her room, she will stop. I promise. I know it sounds mean, to just let her cry, but at this point it is out of habit. She gets plenty of food during the day and as you said, doesnt want the milk, just the comfort of the bottle. I swear, that within 3 nights (day 1 - cried 45 minutes or so, day 2 - 30 minutes, day 3 - 10 minutes) my 10 month old son starting sleeping through the night. I truly thought it was a miracle and thanked my pediatrician for suggesting I do it. It has been 3 months and he only wakes up during the night maybe once a month and goes right back to bed when I come in his room and comfort him/tell him it is still night time etc.
Dont wait too much longer, the older she gets the harder it is (toddlers are very strong willed and the will of a mother hearing her baby cry is not that strong).
I promise, if you dont give in (dont let her see you), make sure she is safe and comfy when you put her down, she will give in to sleep - and you will win the power struggle (it is tough but you can do it!). I would do it on a Thurs/Fri/Sat night so you have the weekend and dont have to get up for work (or your husband) after a night of a crying baby. You will be a much better M./human with a few good nights of sleep.
Good luck!
