That's a good question--and this delightful book weaves a gentle fantasy around the baby who finds himself in that very predicament! A marvelous adventure ensues, taking Baby from the tree branches to a farm full of animals to a ride down the river, and finally on a flight through the night sky into the safety of Mama's arms.
