Pre-programmed

Being around a baby a lot makes you realize just how many things are instinctive and not necessarily learned. I mean, sure there's the eating thing and the sleeping thing, but I think about this regularly when I'm doing something to make her laugh. I mean, no one told her that me sticking out my tongue at her is funny (and it is, let me tell you!), yet she offers a big grin without hesitation. Her brain must understand "funny" (and other things) on some very basic level, probably by making comparisons to what she usually sees (ie, me not sticking out my tongue). I just think it's interesting to ponder all the things she already has programmed into her.
