I absolutely LOVE this blog - written by a mom who started her own school, she believes kids should be allowed the freedom to be creative! I remember being a kid with a gigantic washing machine box and being content to play for days in the thing. Well this blog is along those lines - giving ideas on getting the kids creative with stuff you have around - like making robots out of the stuff in your junk drawer!
