On a recent Saturday I spent several wonderful hours with my grandchildren. They were as happy and carefree as a 2-year-old and a 3-year-old could be. Watching them run and play and sing and explore their big, new world reminded me just how gloriously happy and carefree childhood should be.

My daughter and her husband were there for the occasion. They watched the little ones a little more closely than usual. Probably because they just learned they will become first-time parents in October.
