It's been a little over a year since EXH moved out and we got divorced. He has the DC every other weekend (can't do more as he works away a lot). Eldest DC (7) is still really struggling with being apart from her dad and her behaviour is deteriorating (backchatting, language becoming more babyish etc). I encourage her to ring him whenever she misses him but it's reaching the point where she's waking in the night and wanting to speak to him. He's happy to speak to her whenever she wants which is good. I don't really know what to do or how to improve things for her. Any advice?
