REPOST DUE TO NO ANSWERS---WEANING?

My 6 almost 7 (in a few days) month old daughter likes to fall asleep with a bottle in her mouth. I no longer feed because I am 4 and a 1/2 months pregnant with our second baby (Yes, quick I know) and my milk has turned back into colostrum. She wakes up in the middle of the night and the only thing that will put her back to sleep is a bottle. She doesn't take a pacifier and never has. I've tried it but she gags on it no matter what kind of pacifier it is. I know that it's my fault for letting her fall into this habit but I am trying to break it before she cuts teeth (she's starting to teeth but has no teeth yet). Any suggestions?
