Maybe it depends on where you live. Where I live, I see lots of what the author refers to. Over-scheduling with very little time for childhood where children are able to have some responsibility for their decisions. A book came out a few years ago, The Blessings of a Skinned Knee, which started to turn the thinking around. Away from padded, bubble wrap childhoods and more about letting children take risks and learn something from their decisions.
or the age group. lol.
