When you have children, there are a countless number of firsts. As parents, we carefully document every first as though our little ones’ childhoods depend on knowing the exact date that they first smiled. We track everything from their first teeth to their first steps to their first day of school. I find it sort of funny that we tend to document the firsts of things that will continue on for a lifetime but neglect to document the firsts of childhood and parenthood that are more temporary: the first time we hold hands, the first time our child falls asleep in our arms, the first time we carry our child on our hip. Unlike a smile that will (hopefully) last a lifetime, these are the things that will inevitably end. The part that breaks my heart is that most of these “mommy and me” moments end without warning – we never know which time will be the last time. For me, some of these things ended earlier than anticipated.
