We've recently moved out of MIL's into our new house (finally). Myself, DH and DD(3.5) and DS(18mo) were living there for a year due to circumstances. We had one room (where me, DH and DS slept) and DD slept either in her bed in his mother's room or in bed with her. They have a really lovely relationship and we're very lucky to have his mother's help and in general. We love her lots.
When we got our new house, we got DD a lovely new bed, new wallpaper, new stars on the ceiling, a few new toys, she picked a nightlight etc. We did it up nicely for her and DS. DD wanted to share (still does) and they have to anyway as 3rd bedroom is on another floor. DD was so excited for her new room with her brother. We did everything we could to make her happy and comfortable. Every night, she's cried and screamed for his mother and says she hates living there and wants to go back to nanny. It hurts but I don't take it personally as I understand she misses her. We live in Scotland so we can't go to her house but we did meet up with her yesterday and DD just begged her to take her home with her. She would've probably done it but it's against the rules. I don't know what I can do to make her happier here. She's barely sleeping she's so upset and just constantly crying. What do I do?
