We just toured a Day Care Center. We loved it–great location, good price, most of the staff has been there for years, etc. The one thing that concerned me is that the outdoor play area is covered in small 1″ stones–larger than gravel. And the 2 year olds were out there and a few of the boys were throwing handfuls of it at each other. It also doesn’t seem like a great substance to fall on. Should I be concerned?
