Why are crying babes so cute to photograph?

In the midst of a nice portrait session February '08....

I discovered that baby butts are cute!

So I took a few pictures....

 

And tried an edit (do you like it?  Can you SEE any other edits I made?)

But someone became unhappy....

But... I discovered that was cute too.... so I tried another.

Aren't I terrible?
It remains one of my favorite shots ever.
