So far this term, DS2 (4) has come home from pre-school with a broken sword (his own he'd taken in) and today he'd had the patch ripped off his trousers.
However, he enjoys going, and I suspect I'm more bothered by it than he is.
Can't decide whether to raise it with pre-school or put it down to the rough and tumble of 3 - 4 year olds.
