hi, when i picked up my 3 and half yr old son frm preschool today i had to sign the accident book. he had a cut head nose and all above his top lip. they said thay they had been jumping over hurdles in the playground on concrete i presume from his face, and that he had clipped his foot on one of the hurdles and fell straight onto his face. I was to shocked to really say anything to them when i picked him up. but when i took him out later everyone has been commenting on how he injured his face and when i said at preschool jumping hurdles they were r shocked. I want to say something to the manager there but not to over-react. any advice please?
