My son's preschool organised a short three day school holiday camp. The word 'camp' is used rather loosely here. My son basically just attended school for 3 days (albeit for shorter hours) and didn't have to wear a school uniform. Oh, and it cost MORE than a regular school day. My son had fun though, and that's the important thing.
The theme was 'bugs'. And he learned about ants, bees, butterflies and so on. They made cupcakes on butterfly day... The shot above was taken handheld with a snooted wireless flash off camera left, and the shadows were filled with a table lamp. Background is courtesy of a freebie organiser.
