My ex and I are mid divorce and during discussions about childcare over the summer holidays he told me he would be working a certain day he normally has them and asked if I could - I’m working too - he then told me he’d be happy for our eldest (11 yo boy) to be “pottering around at home”. This means leaving him alone from when he goes to work at 08:30am until he returns at 6:30pm.. longer if he gets held up at work. I am totally against this. He has already given 11yo a set of house keys to his house and leaves him alone for around 3 hours after school until he gets back from work some days which I was not totally in favour of but now I’m worried he’s being left alone at home for longer periods alone. AIBU to think that’s not on?! 11yo has a phone but still..
