What children do in kindergarten?

I was asked by a friend to photograph the children's day at the kindergarten. This was a great day, I love photographing children, especially when thet forget about the camera.
The cutest pics were about falling asleep. In Estonia children sleep in kindergartens from 1p.m. to 3p.m. I have heard that it is not so common in other countries.

But I choose this one here for a blip. Love the emotions.
