As I tiptoed by their closed bedroom door this morning, I heard excited squeals followed by this, "Mama? Mommy? Hi! Hiyeee!" So cute!
I turned on their favorite DVD (Praise Baby) at one point today, and Ethan ran over and sat on his knees on the rug, then patted the space next to him for Kellan to come sit. Kellan did, but sat on his bottom with legs out in front. Ethan leaned over and studied him, then adjusted to the exact same pose.
