A couple weeks ago, Sarah and I discovered that Andrew likes to play a little game. This video shows it well:
Now, Sarah always asks me to do this... in the morning, during the day, and especially before bedtime. She loves to see Drew smiling and happy, and so do I. There is just something about seeing complete joy in your baby's face and knowing that you're the one making them happy. It doesn't hurt either that Drew is such a happy little guy anyway.
