I'm at the end of my tether. I have 5 children oldest is 17 then 14 then 12. The younger two are fine. The older ones have only been out for 'walks' only about 7 or 8 times since school closed. I am sick of nagging them to get out and get exercise, they only end up going when I've had a proper rant at them. I am sick of telling them it is for their physical and mental health, they don't seem bothered and happily sit indoors. They are doing schoolwork most of the time, but ive told them fresh air is just as important. Shall i continue telling them or just give up?
