DP and I live together in a house we bought together last year. He has a DD (8) with ex wife who he split with when DD was a year old. I have 2 DC of my own.
His DD has never stayed overnight with him because mum firstly breast fed until she was 3 so he was unable to have her overnight for those first few years, she has then built up such a strong bond she is unable to spend a night away from her Mum and is very traumatised if this is attempted. However, she otherwise loves spending time with her Dad and being here and throughout all these years Dad has paid maintence.
His DD is now spending more time at ours than ever before, in the last 7 days she has been here for 4 full days and we give her all meals but goes home about 7pm, Dad does all the driving. This happens most weeks now.
We are starting to wonder if he could suggest paying less as we have her for sometimes more meal times and hours than her Mum but obviously maintenence is worked out on overnight stays.
Does this sound completely unreasonable?
