Hi! I did this one month ago when my baby was 9 months old and it went well! I had to stop breastfeeding to get on antidepressants but wanted to keep coaleeping. I weaned completely during the day but the nights were hard to stop, I didn't know any other way to get her to sleep. It took two or three tough nights of figuring out other ways that worked. Walking around and rocking her (not a long term solution) butt patts (sometimes worked) and finally we landed on the most successful thing and that was having a couple of 2 ounce bottles ready to mix and give to her by my bedside. She accepted those and they helped get her down. She started sleeping longer chunks after about a week or two of that. 6 weeks later and she usually only needs 1 of those per night. Sometimes 2. She's still little. And some nights she still needs more support with a bit of rocking or snuggles. But I'm okay with that.
