"Nathan has pajamas on his head"

Okay, in order to understand the following pictures there are a couple of things you must do:

1. Watch this video on YouTube.  It is one of Nathan's favorite singers and a song that has helped him recognize certain animals.
2. Now, watch the video a second time and instead of singing "Laurie has a pig on her head" and so on, sing, "Nathan has pajamas on his head"
3. Finally, view the pictures below.  You will understand why some of the pictures are blurry because Nathan was actually bouncing along with me as I was singing about his pajamas on his head.

Amazingly, Nathan kept the pjs on his head long enough for me to get the camera out and snap several shots (even though they're not the best quality - maybe do to the bouncing and dancing around?!)
