My 4 year old daughter broke her arm the week before she started primary school. She has been staying in at dinnertime playtime as they come out of their reception playground and play with all the other kids up to year 2.
She really wants to be allowed to play out at dinnertime, but i am scared a bigger kid might knock her over and break her arm again.
I was worried about this, and made dd go to the indoor playtime club until the cast came off. I don't know whether that is overprotective or not - I just wanted to reduce the risk of accidents. Her arm healed fine. As did those of several other kids who were allowed out. One boy did have an accident while his arm was healing, which obviously has implications for longterm strength. Tricky one.
