The Fry started giggling just a little bit about a week ago. It mostly sounded like blowing out spittle or something, but I could tell it was a laughing noise. But the other night, I was telling DH about how the Fry had managed to actually hit a couple of the animal noisemakers in his exersaucer, and they made the MOO and WOOF WOOF sounds and he was like CRACKING UP at me making the noise, so I did it again and he like threw his head back and SQUEALED with laughter. So I kept doing it and he kept laughing. I swear it was the absolute highlight of my week, that’s the best sound I’ve ever heard.
