Hi C. -
We had the same problem with our first and third babies (both girls). Both times, we tried all kinds of tricks, and they didn't work. The reason they didn't work is that the baby just wanted company and would take any bottle in order to get the company. Both times we ended having to make her cry it out. We didn't respond to her at all. (We tried the gradual timing - 5 minutes, then 10, then 15 - it only made them cry harder) This is a heart wrenching and exausting process for the first 2 nights - but by the 3rd night, it's not too bad. By the 4th night - no waking up at all. I recommend getting some sort of white noise maker (fan, air purifyer, white noise machine, etc.) to turn on and help you get through the crying. I promise, everyone will come out of this unscathed. The end result is worth the work. Your baby will learn how to sooth him/herself, and you will get real sleep for the first night in 18 months! Plus you'll be done with bottles! If your baby is 18 months old, the sooner the better - the older they get, the more stubborn. I would still give a bottle at nap and bed times if you want, - and continue to work on weaning those if you want, but we found cold turkey for the middle of the nights worked best. Do it on a weekend when you can maybe afford to loose some sleep, by monday you'll all feel much better! Good Luck!
