Can I get a smile?

I've been trying to improve my focus...which is a difficult task with very active children. Of course, they are my most accessible subjects, so I can't be too picky. However, can they not just give me one smile?! Or maybe even just look at the camera...in Knox's case. He's already rebelling against the camera...no amount of begging and pleading will give me just one sweet little smile. I'm hoping he outgrows this stage soon:) And Lizzie...well, she's just always got that tongue out...but at least she'll look at the camera! I promise she smiles all the time!
