Panels activated by sliding tabs introduce youngsters to the human body.

The information is presented in matter-of-fact narration and captioned, graphically simple art featuring rounded lines, oversized heads and eyes, and muted colors. The sliding panels reveal new scenes on both sides of the page, and arrows on the large tabs indicate the direction to pull them (some tabs work left and right and others up and down). Some of the tabs show only slight changes (a white child reaches for a teddy bear, demonstrating how arms and hands work), while others are much more surprising (a different white child runs to a door and on the other side of the panel is shown sitting on the toilet). The double-page spreads employ broad themes as organizers, such as “Your Body,” “Eating Right,” and “Taking Care of Your Body.” Much of the content is focused on the outside of the body, but one panel does slide to reveal an X-ray image of a skeleton. While there are a few dark brown and amber skin tones, it is mostly white children who appear in the pages to demonstrate body movements, self-care, visiting the doctor, senses, and feelings. The companion volume, Baby Animals, employs the same style of sliding panels to introduce youngsters to little critters and their parents, from baboons to penguins.

Genial starter nonfiction.
