In the very beginning with 2 of the other boys. He was having so much fun.
If you can click on this and enlarge the picture you will see the huge proud smile on his face.
She was telling him he had to lay on his back before he could leave.
He did lay on his back very reluctantly and then she put her hand on his throat to keep his face straight up and not looking down. Putting your hand on a 4 year olds throat while they are already in panic mode is not a good idea. At this point (ok before this) he had shut down and when someone panic's you dont teach them anything. They arent learning anything untill you calm them somewhat.
