What would you do? We are moving back to UK at the start of the summer holidays, to a new area, after 4 years abroad where security has been a real issue so DCs haven't had the space to be independent outside the house. Both are pretty sensible, (DD just 14, DS just 11) and have spent afternoons alone (& DD longer), but we'll have 2 weeks getting to know the area (and hopefully find some activities they'd like to do) before I start work full time in August. But its quite stressful for them joining summer schemes when you know absolutely no one in the area, so I think its possible the planned activities side might not work.
They get on fairly well, so could look out for each other or check in with each other too, and I'll be working in same town and accessible by phone and could come home in an emergency, - and I think DS will be delighted just to hang out in a park with his skateboard - & they are going for a residential camp for a week halfway through August, - but do you think this sounds realistic or negligent for two weeks? Park, finding feet, mooching at home, ideally possible activities but no active adult oversight. They could go and stay with relations elsewhere, but I think it would be far better for them to find their feet & ideally have fun in the new area - if it isn't too overwhelming and they feel dumped.
