My DH and I had planned to spend a few days away next week and my kids were to go to my Mum's. However, we decided we were too skint to go away and would do day trips instead. He still expects my kids (who are his step children) to go to my Mum's so he can "have a break" from them. They are 12 and 15 respectively and pretty good, not rude or badly behaved. They already spend one or two nights a week at my Mum's or sister's house (Friday and Saturday this week). I think it's a bit much to expect Mum to have them for three nights when we won;t even be going away. He is in a massive sulk because he was looking forward to having a break from them. We have Wednesday-Friday off and they will be going to my Mum's on the Friday. AIBU? Should I ask Mum to take them anyway? They will be away for all of August visiting their Dad, so he will be getting a break soon anyway. We will still have DS3 with us who is three years' old.
