It was a telling commentary on the times four years ago when Liz Baird came up with the idea for Take A Child Outside Week. The simple notion that you needed to dedicate a week to encouraging kids to go outside and play would have been preposterous just a decade earlier. Yet with the proliferation of video games and parents increasingly fearful of threats real and perceived, kids were staying inside — and being kept inside — in record numbers. The dilemma was chronicled by author and advocate Richard Louv in his 2005 bestseller, “Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder,” an account of how our kids had gone from being weaned in the wild to garrisoned in the great room in less than a generation.
