What growing up means to a 2 year old

So here's an overview of a discussion had between Andrew and Angie earlier today as he saw Keller sucking away at his pasi:

Andrew: "Mama, Mamu (himself) too big a pasi."

Angie: "That's right."

Andrew: "Baby have pasi."

Angie: "Yeah, baby have pasi."

Andrew (with a big grin): "Mamu have pancake!"
