In recent days, more than eight years after our first child was born and more than two years after our third, we've retired the stroller and the Pack 'n Play. Tonight, it appears, we're done with the crib. The final moments in the high chair are nigh, leaving us only with diapers as the last vestige of little children of a certain age.Clinging to the memories of their youngest days, clinging to our children in a capricious world.
