It is always a great pleasure to watch the boys at a park, playing anyway they choose; having some spontaneous fun supported just by some space and simple structures. No structure, no rules, unless they choose to invent some.
What imaginative play items will they be trying to sell you from their virtual shop under the slide? Who will be king if the castle today? What will they learn through play and exploration? How will they interactive with each other and any other children? Often it is heart in the mouth time as the boys develop and test their new skills!
