Everything children need to learn they can and should learn through play. One of the most misguided notions regarding early childhood education right now is that play is frivolous and that real learning involves sitting. It's nonsense.

And play stimulates nerve growth in the portions of the brain that process emotions and executive function. Rough-and-tumble play teaches us how to cooperate and play fair.

Inevitable movement comes into play with the excitement of whether or not the person is going to be able to do it.
