You sound alot like me. Slightly different. Me-Single mom one bedroom apartment at the time and neighbors I didn't want to bother with screaming. So I put my daughter to bed with her bottle everynight it was a security object and worked like a charm. I too was to tired, exhausted and frustrated to do anything else and hey it worked great she was out in flash. I did switch her to water only probaly around 15mos.She would take a bottle to bed, and wake up for a "refill" 1-2times a night, I'd half awake go to the bathroom turn on the water and give her the bottle.Talk about having mommy tied around her pinky. This continued til my daughter was 2.5-3 years old. YES didn't sleep through the night nor did I til 2.5 years old. Let me tell you, they don't outgrow this and it isn't a phase it's a bad horrible habit. The longer it goes on the harder and harder it is to break. If I ever ever have anymore children I'm taking the bottle away at age1 all together. The only thing that worked was letting her cry it out, yes it sucked for 2-3 days but that's about it, I warned my neighbors what I was doing and I did it. The first night sucked the second was easier and the third wasn't to bad and then it was a forgotten thing of the past.
Now having a milk bottle in bed for 12+mos, then having a bottle with milk, juice during the day for 2.5 years, plus sippy cups and then doing strictly water at night my daughter still ended up with screwed up teeth.
At 3 years old she had 3 cavaties, and her enamel is wearing off her teeth.Thank god for a second chance with permanent teeth later in life. They look pretty and normal it's not obvious by just looking at her but she had alot of problems with her teeth. After we took care of her teeth with the dentist and took away the sippy cups and bottle she hasn't had any other problems or cavaties and she's 6 years old now.
And my daughter being obsessed with her bottle til almost 3 years old she is 6 now and still occasionally asks for one. And I look at her like she is nuts.
My advise let her cry it out, if you can't do that atleast give her water. If she won't take water start diluting her milk each night til your down to just water.
Good luck it's hard taking something away from out kids that they love so much but is so bad for them too. It's like they love candy but you won't let them eat 5 lbs. a day you set limits.
