Tim was holding Emmeline on our bed so I could get ready to sleep, and Jack climbed up and sat beside him. Tim was doing the universal baby bounce-and-sway to keep Emmeline content (you know the one--same one you find yourself doing to that bag of flour while you're waiting in line at the grocery store when the newborn is a month old).
When I came into the bedroom, Tim said, "Look at Jack." I glanced over and Jack was drinking his milk and doing the same bounce-and-sway that Tim was doing.
A little later, Jack looked at me and said, "Daddy Dance." and started doing the little swaying bounce again. "Daddy dance with Embaline."
