From chapters.ca:
A beautifully illustrated celebration of the many things babies can do from a talented author and illustrator team, Susan Meyers and Hiroe Nakata. Whether two- legged or four- legged, babies have a lot in common. They run, hide, jump, tumble, tug, cry, munch, and snooze, as babies of all kinds do on the pages of this heart- warming book.
