Everything went well. They loved the dogs. No one got hurt. They ate what they were supposed to. From my Facebook status of the day, you can see really how things went: Have the pleasure of hosting my nephew's little ones for the night. Score: Ellie and Dallin asleep by 7:45; Piper Jo didn't nap and still awake.
(These pictures were taken another time when we were babysitting up at their home.)
