My wife got in trouble as a substitute teacher at our local public school for allowing the kids to slide on the frozen ice puddles last winter.
...Actually, I think she was showing them how to slide on the puddles. But anyway.
Jeez. Contrast it with this article in NY Times on a different approach to parenting...
Or standard German approach with little ones which is get them outdoors running around in grass and trees regardless of the weather. Much healthier.
