Very funny! When I was a kid we only had one male babysitter - he used to tie us up and we'd try to see which one of us could wiggle free first - he was our favorite babysitter, but it would probably be called child abuse now.
And who will have the most fun at the end of the day ? The caretakes, the children or the parents ? They still seem to have lots of fun so I guess to come home and fall straight asleep. The image does not express any fear, so looks like a real invitation to have fun. Willem
