I wondered if anyone has any advice to offer. DD (5.9) stays at her nans house every Friday night and stays at her others nans house every Saturday night. The problem is, neither of them will let DS stay even though he gets really upset and asks to stay. DS is 2.7 and is out of nappies day and night. How so I resolve this without seeming spoilt (if you can't have both then you can't have any!) Do I just leave things as they are and try and get DS to understand (even though I don't) or do I put a stop to DD staying out? HELP!
