In the fall of last year, my wife and I signed our 3-year-old daughter up for an indoor soccer skills class. And right away, she loved it. We loved it, too. It was fun to watch EJ work on fundamentals like dribbling and kicking — her game face would emerge, her little tongue would come poking through her lips as she concentrated — but it was even more fun to see her laughing as the coach incorporated silly games like Red Light Green Light Black Light. (The black light ignited the field-wide toddler dance party, obviously.) There was just one problem.
