Neighbour has got trampoline for his kids - one same age as mine. She has been wistfully looking out window, and was this afternoon kindly invited over. he mentioned that they were going to put on the protective netting etc. I allowed as how I had read worrying statistics about injuries to children caused by multiple kids on trampoline, no netting etc.
Occurs to me that he probably thinks I am nuts to allow my daughter to cycle on the road, and to run on ahead of me when we walk places, etc but to worry about the trampoline. I'm not so sure - when walking she's very good at watching for cars in driveways, and cycling I watch cars, car doors obsessively. To me the random risk of being unintentionally headbutted by another child, losing balance and falling off trampoline etc much more worrisome. But I suspect i'm in a minority.
