My 4 year old DS has come home from school on Thursday, Friday and today with ripped trousers just below the knee (Monday he was in someone elses trousers coming home - typical PE day!). We've had plenty of ripped trousers over the years but three in a row?! I had ordered him two new pairs at the weekend (he needs M&S skinny fit, nothing else will fit him). So our three pairs are now back down to two. He ruined three relatively new pairs (bought in December as he went up a size) in three bloody days! Would it be unreasonable to ask school to check if there is something at child knee height that may be broken, causing this? Two damaged pairs I would have brushed off, but the 3rd has tipped me over the mad woman edge!
