Well, we've made it 4 weeks with the band/helmet. So far so very good. On Wednesday we had an appointment with Mr. Todd and McClellen's head has made great progress towards our goal shape. Some of our appointments are just checkups and some are for measuring the changes on her head. This appointment was a measuring appointment which means we got to get "scanned" The scanner gives us the most accurate measurements. Here is a picture of the scanner. The base is a lion and the scanner sits on its back. There is a baby doll laying on its head and you can see a sample helmet up there too. They use these for demonstrations.

Here is McClellen on the scanner. She wears a pantyhose-type cap to give her a really smooth head. Otherwise, the scanner would pick up on her hair and take that to be the boundaries of the cranium.

She is still in the scanner (or is supposed to be. She was hungry for lunch here and was NOT cooperative. SHe was trying to touch the red scan light) and the scanner moves back and forth in the side panels. All you see is a red light pass over her, much like a bar code scanner. It just takes a few seconds.
Here is another hilarious picture of her at a previous appointment but it shows the little cap.
"Do you see what I have to put up with here?"
Her head is changing beautifully and we will go back in 2 weeks for a checkup appointment.
