Years from now, your children’s children will study this week in history classes.

Want to make your own history? Yes, you can — with a family photo session by Karen Mordechai.

A specialist in documentary photography, Mordechai works with clients to select a family activity then chronicles it over 90 minutes — anything from a park outing to baking cupcakes to bedtime stories.

Shoots aren’t about orchestrating the moment. Think of her as an invisible observer of your family, recording both the mundane and the meaningful (after all, it’s the mundane things that will one day be meaningful).

The resulting set of four-by-six images and online gallery will capture the glory of your brood as they are today.

Before they change.
