Greg came home that night and we decided to duplicate the giggle-inducing move. This time, instead of giggling... Jack laughed! Greg and I got to see his first laugh together. I grabbed Greg's iphone and caught another laugh on video:
True, our son sounds more like a squawking parrot than anything else... but it's definitely a laugh.
I am surprised by how excited I am to hear Jack laugh. It feels even more monumental than seeing him smile. Babies smile (reflexively) from birth; you could call it a grimace or blame it on gas. It's never clear when the smile is a "real" smile.
But a laugh? Yesterday Jack didn't laugh and today he does. I can be sure, when he laughs, that he is truly happy. What a beautiful sound!
