My son was kindergarten age, this was in 2005 and he had thrown his metal train up in the air. When it came down he missed it with his hands and caught it with his face instead. The school sent Child Protective Services (CPS) to our home to investigate. When they discovered it was an accident the teacher felt horrible and apologized profusely. I thanked her profusely. I would prefer to know she cares enough to contact CPS. Things have changed a lot since I was in Kindergarten back in 1977 although the unfortunate truth is there’s still so much abuse never reported.
