Ex-h has the DC every weekend for 2 overnight stays. He has the matrimonial home which formerly had 3 bedrooms, well kind of. One he uses as a study (dumping ground for stuff), a very small bedroom with enough room for a bunk bed only and his bedroom. Okay, so far... he has now invited his elderly mother to live with him and she'll have the DC's old bedroom (the one with the bunk bed). The DC are to have their bunk bed moved into their father's room. The DC are DS who is 7 (asd) and DD who is 10. DD is not happy with this future arrangement and neither am I. Is this situation fine? Appropriate?
