portraits of my babies

I started my "how to use your fancy camera" class tonight, and as luck would have it, the proofs from the kids' photo shoot were also ready.  The class may have taught me how to theoretically take good photos, but man oh man.  These proofs make me ridiculously happy that I had no skills and decided to go with a pro.  

Now we just have to narrow it down to which one will get framed over the mantel.  How do I choose just one?  An impossibly difficult task.
