Way too big, way too quick

Who is that big girl, with screwdriver in hand? Why, it's Ava, taking apart her crib. Taking apart her crib? Why would she be doing that?

Because she's a a big girl, of course! With a new set of bunk beds to share with her big sister.

My, my. How could that happen just so quick? First the nuk. Second the crib. Next up? Diapers!
