Ever since Jack’s premature birth, we have a special affinity for the NICU (neo-natal intensive care unit) Today I spent a little time with Coen and Zion, twins who were born too early only a pound and a half each. Thank you to the doctors and nurses at @seattlechildrens The boys are doing fine. Although they’re both missing their big sis.

Madisen is #strongagainstcancer. What an awesome kid with such a beautiful smile. She’s a lover of art and fashion and she’s going places. Thank you @seattlechildrens for the opportunity to come by and brighten some days. My heart is full. Proverbs 3:27 Don’t withhold good from those to whom it is due, when it is in the power of your hand to do it.
