Well I know that's not U in itself ...
I sometimes struggle for things to do with my 9 yr old and 11 yr old DSs that take them out of the house for fresh air and exercise. We don't have a car, so any outing involves some fresh air, even if it's only the walk into town to the bus stop.
They are horribly resistant to suggestions of spending time outside the house - we have loads of great walks nearby, river, beaches, hills, swimming pool, but no, all they want to do is spend time indoors with their electronic pacifiers.
In the summer we do bike rides now and again, or potter about on the river (have a canoe), this weather isn't really conducive.
They are also resistant to organised sports (although last term I insisted they choose one thing from the extensive list of after-school offerings; but that isn't faaaamly time).
We managed to swing a walk past them last week when a friend with 2 dcs came to the house and we took them all out together and they did fine; however when another friend offered to take us to the beach with a pile of kids tomorrow, my 2 absolutely refused to go.
Help!
