This sequence of photos was taken at this morning's Toddler Craft and Cookie Exchange Party. It raises the question: Is it possible to keep five toddlers on a couch long enough to snap their picture?
I've got to hand it to Sven and Shane, who in life are two of the fastest balls of energy I've ever met, but sat still and made eye contact throughout the attempt (Shane, ever the professional model, even waved merrily at the camera). The usually-mellow Ezra had a slight meltdown, Sophia lost patience with and abandoned all the boys, and Ben departed with an air of stoic independence. We five parents with three cameras stood around laughing hysterically, and our children glared at us as though we were ruining their lives.
