Joy operates well in context of routines (heck, don't most people?)
One particularly functional routine we've developed is at diaper-changing time. It's Joy's job to put away the diaper cream. She has to open the changing-table drawer, put in the tube, and close the drawer back up.
This morning when she went to open the drawer, there was a problem. She had the diaper cream tube in one hand, and a board book in the other. She tried to open the drawer a couple of times with the hand that contained the tube, with no success. I was half-expecting her to give up -- she's got such a short attention span, and often takes the path of least resistance. But no. She thought about it for a second, put the book down on the floor, completed the routine, and then picked that book back up!
It didn't have the feel of an Elvis sighting... I suspected that the King had not left the building...
Then this evening a similar situation occurred. This time Joy had the tube in one hand, a chewy ball in the other. Without missing a beat, she grabbed the chewy ball in her teeth, completed the routine, and then took the ball back out.
