although your daughter is still very young, I found with my dd that because I had a solid routine right from the start, she adapted to new environments very well, as I stuck to her routine wherever we went. So if she has been with my mother in law or my mum for the day/ night, they have followed her routine to the letter and she is comfortable and relaxed because she knows what's going on, even though she is somewhere different than home. I hope this makes sense!
how is your routine going at the moment?
