When I change Henry's diaper on the changing pad, Emme drags her stool over so she can stand up and talk to him while I work. Every morning she requests that I change him on the ground so she can see him better. (She must miss him after going a whole 8 hours without her Henry-fix.)
So every morning we lay out a blanket and make our diaper-change assembly line. We change whoever is poopy first, and then get everyone dressed for the day. Emme loves to be able to talk to Henry and touch his head while we hang out. And Henry seems to love the sound of Emme's voice -- he'll crane his neck to follow her sound wherever she goes. These two are going to be such good friends!
