We've been teaching Otto how to use sign language, and at 5 months, he can already sign when he's hungry.
He's mostly just holding he's and in the air, nd starting at it but then we ask him if he wants a "baba" and he reaches for a boob lol.
It's really incredible to watch every little milestone they hit. I've said I don't want him to grow so fast, but man it's so cool.watching him get bigger.
