My daughter sleeps in her own room in her crib. We moved her there just before she hit 2 months. She's slept all night since we moved her and so have we, best thing we ever did honestly.
@mamatojessegrace her sleep honestly didn't change...it was better for me and my partner though not having to worry about wake her when I get ready for work and things like that
Moved our daughter around 5 months and she transitioned very well...we had all her toys and swing in her room so she spend a decent amount of time in there so it wasn't unfamiliar to her.
