I found out that both David and Erin are commercial airline pilots and while that can be a busy, stressful and away-from-home job, it seems they've got a pretty good system worked out so they're not away for very long at once.
Since our session, they've welcomed a second son - congratulations!
Thanks for letting me follow you around the beach on such a lovely day to capture your growing family; I hope you are finding a groove with two boys to take care of!
