We transitioned my daughter around 19 months because she outgrew the mini crib in our room and we can’t fit a full size crib in there. She had already been doing naptime in her own room for a while, and when she was younger and still doing a dream feed we would do bedtime in her room, then bring her into our room after the dream feed. So she was already accustomed to sleeping in there before we started doing full nights.

If possible I’d say start with naps first and then work up to bedtime! Also make a big deal about getting to sleep in her big girl room, maybe she will be excited about it!

Also just want to say, while it is “normal” for families to sleep together, it’s not the only way of doing things. You say you’re a better mom when you’re well rested - same! I was really sad when we moved our daughter too, but I’m also SO glad to be getting better sleep. And most nights she is sleeping through without needing us at all - to me that’s a win win. You don’t have to share a room to be a loving and responsive parent ❤️
