Baby laughter is utterly contagious. I adore it when Ben laughs, and since he's a happy kid, he laughs often and heartily. It's so much fun to figure out just how to make him laugh. My dad discovered tickles under the chin; Steve discovered eyes closed to eyes popped open. I tickle him on his little feet and in his armpits. Here's a little video with a sample of just how fun his little laughs are.
