You're doing a great job @zebracat!
Dd has some things arranged already - a week volunteering at a Christian festival in Cornwall, half a week's teen camp and a day at the Reading festival, plus we're going away the last week of the holidays. She will fill the rest of the time with social stuff - I tend to have to book her in in advance if we want to do something social as a family, or visit other family members!
She's having a chat with an OT we know on Sunday (instigated by me, but she agreed to it!) and I'm hoping she might get some work shadowing off the back of it. Or if not, at least she'll have a better idea what it involves. I'm not even mentioning school work! She'll do whatever she has to do.
In terms of how much to do for them, I think it's totally child-specific, depending on their needs. I've never done anything to do with academic work for dd, no nagging re homework, no help, nothing. But she does tend to need emotional support.
Ds on the other hand is incredibly independent in many ways, never asks for lifts - would much rather take 3 or 4 buses on his own! But totally disorganised/clueless/unmotivated when it comes to school work. I've decided to save all the GCSE revision material which is coming through now in advance of his Sept exams and organise a revision schedule for him. I know he needs to learn to organise himself, but I'm hoping sixth form, when he's only doing 3 subjects that he likes, might be the time for that!
