What is Happening to My Hair?!?!?

Here's me at 1 week old. What a full head of hair!

Still at 3 months old, I'm looking good.

4 Months old and everything seems in order. I mean, my head is growing, so I expect some decrease in density...

Oh Boy. Here's a picture of me at 5 months. As you can see, its getting pretty sparse up top!

Here a photo of me as of yesterday. I can't even look into the camera. Mama says its normal and that it looks like my new hair is coming in blond, but I think she's pulling my leg.... only time will tell.
