You know how moms of boys talk about what it's like to raise boys? That they're loud and pee all over the seat, make gross noises, etc etc.
S isn't a kind of guy who encourages such behavior. Not that he will squash it, but he won't teach it or otherwise introduce it.
The other day, I listened to this all the way home from daycare: "hahaha Mom I farted on my arm!"
over and over and over again.
Did I mention that Baby Z copied X and started making the same noises by blowing on his hand?
X thought that was HI-larious.
