i picked up my son today from preschool and was asked to sign the accident book. they had been playing hurdles outside on concrete. my son had clipped one of the hurdles with his foot and tripped up onto his face. He has a cut head nose and all above his lip. i didnt say much at the time but when i took him out everyone has commented on how he injured his face and when i said at preschool they couldnt believe it. What should i say when he next goes. i was going to spk to the manager and say if the kids are to jump the hurdles again please ensure my son doesnt join in. i know all kids will trip up but i dont think it was right for the kids to jump hurdles on concrete. Any advice please.
