From beloved author-illustrator Rosemary Wells comes a sweet and funny picture book about a baby who has such a good memory, his parents think he is a genius!

Little Koko's head is an inbox. Everything fits inside, Mom's bath time song, Daddy's breakfast yogurt song, and every other word they say! Soon Koko's head is stuffed full of words, and once he starts to say them out loud, there's no stopping him. He's a genius in a high chair! But what happens when Koko gets his hand on a phone?
