It was early on in motherhood when I came to the realization that if you distill parenting down to its essential essence it is quite simply an exercise in letting go. You learn to let your toddler climb the stairs to the soaring heights of the playground slide and you trust with a certain amount of coaxing and the aid of gravity that your child will return to you. You drop you child off for the first day of nursery school and even though you've fantasized about having a few hours to yourself for years the minutes tick by like an eternity. On almost a daily basis, you get glimpses into the future. One that at times seems to be happen way to quickly. Take Saturday, when I got the telltale glimpse to the fact that seven is one third of the way to 21.
