The Giggle of Nicholas

This giggle of his is priceless. I can tickle him right in his armpit and he laughs SO hard. The laugh comes from somewhere deep down in his belly and doesn't stop. It's the kind of laugh that will make any person laugh just hearing it. Yesterday we got into a tickle match and I just kept tickling him because I wanted to hear that funny little laugh. I wonder if he'll always have this deep bellied laugh? I guess when he's 40 I'm gonna have to jab my finger into his armpit to see if it's still there.
