Knudsen or Newton?

Not unlike her brother, Ellie fancies herself something of a scientist. She's big into testing gravity, especially with all the "buddies" in her crib, and her (hopefully) empty bowl when she's done with her meal. Today I caught her busily sorting shapes with the tried-and-true Tupperware sorter. Can't you just see the wheels turning?
I love how she purses her lips when she's concentrating. Or, um, completely pissed off.

I'm sure she'll be solving Rubik's Cube in no time.
