I agree - hard as it is sounds like she is just adjusting, and if she isn't distressed I would take her back tell her it's dark/night time and time to sleep and keep resetting. Sounds like she is settling well although in the midst of wake ups it is hard to feel it! Funny story - when J started sleeping on his mattress on the floor, one night in the first week I heard him crying and went into his room and he was standing inside his pop-up washing basket thingy crying :O I have no idea how he got in there I don't think he knew either but his cot used to be on the other side of the room so we think he was trying to find it! Too cute!
