When a mother bird says it's time to go to bed the little birds hop right into their nests. They never say 'Oh, please, please, please, let me stay up only five more minutes.'"" Similarly the little goldfish never ask for a drink of water, the little kittens never ask for another story, the little kangaroos, flamingos, bats, and other creatures are equally obedient, and ""When your mother says it's time to go to bed, you always give her a great big kiss and say goodnight!"" Bedtime procrastinators will recognize their own excuses, but they might end up feeling conned despite the pictured kid's broad wink and hidden flashlight. Equally marginal are Eaton's smudgy blue and reddish illustrations, slack as pictures despite a few incidental furnishings that help break the monotony. Toss a coin.
