Dc1 (14) and dc2 (12) argue and bicker constantly (pretty much). Dc1 is a 'very full on' teen, but close to my mum. DM has offered to have all 3 so that DH and I can go away for 3 nights (20th anniversary). Having just come back from holiday, it's fair to say that my poor mum is likely to find all 3 very hard to manage. She's in her late 70s too. So I suggested she had the two oldest and that we took the youngest with us. Not ideal but there isn't anyone else we can ask. However, the oldest 2 have let us know they will be jealous. They haven't made a big deal out if it (yet...) A friend said they thought this was a 'spiteful' thing to do. Is it? We have had one night together away from the children ever. That was our 10th anniversary. AIBU?
