*We are talking about (or I was, anyway) monthly duvet days.
What I am saying is that allowing your child very frequent days off in circumstances where it isn't strictly necessary, will have an academic cost. And that is all I said.*
Pengggwyn I think we basically agree, children should aim to be at school all the time? I think the only place we disagree is you implying that monthly duvet days are by definition not 'strictly necessary'. I don't see how you can proclaim that without knowing the child, background or circumstances. Maybe those days off are preferable to a child saying 'I can't cope' and leaving, or other behaviours.
Of course these days off will have an academic cost - whether or not they are strictly necessary! The challenge is tossing up that academic cost against other costs, and only a parent/child can decree that.Ideally I would say schools should be involved too, but my sense is that they can't bring themselves to sanction any flexibility.
Of course sometimes the avoidance needs to be challenged and that is the best thing for the child.
I wish there was more variety of school/timetable for different children, but then I am quite a blue-sky thinker and wish that the whole workplace was more flexible.
