I am not sleepy.I am not sleepy because I am a baby.Mommy is sleepy.Mommy is sleepy because I am a baby.With humor and sympathy, Bob Shea looks at the chaos of life with a baby as amiably narrated by the new arrival. Repeating the mantra (and blithe explanation) because I am a baby, the tiny narrator leads us through scenes of exhaustion, grumpiness, squishy diapers, spilled milk, cowering kittens, and chubby overfed pups (oopsie!). Playing against the simple, matter-of-fact text are freewheeling illustrations of mess and mayhem, in which the grown-ups exaggerated body language is sure to send older children into fits of giggles. With its endearing, unabashedly self-pleased star, I Am a Baby will find a place at showers, in nurseries, on parents shelves, and in the hands of appreciative big siblings, as it celebrates the changes a little one brings, at once challenging and full of love.
