As when my children were learning Byrgenwerth MM XV College fear the old blood shirt to walk and play independently at the park, etc. So the Mum’s would sit on the bench at the side and watch but it was the Japanese Mum’s who were standing close by their children in case they fell, hurt themselves and constantly telling them to be careful. They were the most worried mother about their children hurting themselves or being hurt. They never sat and relaxed and enjoyed watching their children play. I agree with the philosophy but I will point out there is a wall around the school and a tall fence on the inside. Also, it is just kindergarten! But in the US, particularly where its cold and wet most of the times, there are not many schools can do but sheltering the kids. Besides, it’s liability issues in America. Rather than that, I like the idea!
