I fed DD to sleep til she was 16 months, it was the last feed I kept and we decided to stop to see if it would help her sleep longer through the night (it did).
The first night I didn't feed her she did really cry to begin with, then fussed and moaned interspersed with dozing. Took about 2 hours of cuddling/gentle rocking for her to get into a deep sleep, at which point I put her in the cot (and she slept through for the first time ever!)
Next night was just a bit of a cry, then it just got better and better - she seemed to accept there was no more feed before bed after only a few days. My husband started sharing bedtime duties (which he'd never been able to do before as she wouldn't take a bottle) which was a great relief!
Unfortunately 4 months later we still hold her until she's asleep, after storytime and lights out. It only takes 15 mins ish tho, then we put her in cot and she sleeps through the majority of the time.
I just don't really know how to make the next step to getting her to fall asleep in her cot. But I'm so grateful for a good nights sleep, such a change from when I was BF! I'd do it again though despite the lack of sleep, as I loved the bond and felt it was best for DD
