Otto's been smiling and cooing for awhile now, and he has this cute little sigh-laugh - it's the cutest when he does it in his sleep. But last night, he full-on laughed out loud and it was the greatest thing! Andy and I just sat there laughing along with him. And to our delight, he did it again tonight! Our boy is so fun! Unfortunately, we didn't catch his full-out laugh on film, but here's one of his adorable smile!
