There's a baby in there. At least that's what Mama and Papa tell me. I don't think so. I was in there once, four years ago. I didn't see anybody else.

A little boy chimp wonders what it would be like to have a baby brother or even...a sister? But no matter what anyone says, he still doesn't believe there's a baby in his mother's belly--until one day, there's proof! This delightful text by Dandi Daley Mackall is illustrated with rich humor and detail by Carlynn Whitt in acrylic, colored pencil, and wax crayon on watercolor paper.
