Here’s Hayden singing the theme to “Wonder Pets.” Papa Sutton knows all the words, too.

Funny story: during a recent afternoon “nap” — Hayden hasn’t been taking to nap time so much these days — he could be heard saying, “Are you in trouble, Peanut? Are you in trouble?” Peanut is the tiny stuffed elephant you see in the video. Then, Hayden started saying, “I’ve got to help you!” and he started singing the Wonder Pets song. When we went in to get him, sure enough, Peanut had fallen out of the crib.

Silly kid.
