Do other people's dcs go out? Do they spend time with friends? Or perhaps take part in hobbies?
My 12 and 13 yo refuse to join any extra curricular activities, school or otherwise. They both have a few friends who live very locally to us. Their friends seem to be busy most evenings and weekends with activities (tennis, martial arts, Guides, youth club etc) so are not available for my kids to spend time with.
I have nagged, encouraged, cajoled etc etc, but they won't join anything. We live in a medium size town and there's quite a bit of choice, but they simply won't.
When they were little I ferried them to Beavers, swimming, gymnastics, martial arts, street dance etc, but since they started High school they do nothing. Go to school, come home, stay in their rooms, maybe play out for the odd hour or so once a week when a local friend calls, but that's it.
The thought of a looming 7 week summer break with both of them hanging around the house all day is already filling me with dread. I used to enrol them in summer activity days at the local leisure centre, but they're too old now to be accepted.
