How we mark the stages of our children's lives subtly changes in the span of just a few years. Early on, it's the things she starts to do: her first day of school, her first soccer game, her first violin lesson. Before long, it becomes the things she stops doing: the day camp she's too old to attend, the grade school she moves on from.
Marking ends as opposed to beginnings is a profound change for a parent. It makes you concentrate on things past, regret missed opportunities, and even heighten your own sense of mortality.
But parenting is not about the parent. Even if I am significantly "past", she is all "future" right now. Setting her on her course is what parenting is about.
