I thought he might like to swing a bit, or go down the slide. But first he tried climbing up the slide, which didn't work too well, so I showed him the ladder, which he climbed with a bit of help and went down the slide. Once. After that he went straight for the sand. Typical boy, I guess.
Sand in the hair. Sand in the sandals. Sand on the clothes. Once I finally got him out of the sand and into the house, it was definitely bath time.
