Observe Bubby. Observe Bubby's toy (foreground). Observe Bubby ignoring her toy and playing with the box of little, choking-hazard Smurfs.
The Smurfs were Jon's when he was a boy and now the girls have them. But Peanut, being the older child, thinks of them as hers and hers alone and does not intend on sharing them with Bubby. She is, after all, three years old. So we're working on sharing. And when she's off to bed, Bubby takes advantage of Peanut's absence and goes straight for the Smurfs. Clever girl.
