Doreen Cronin makes the most of young children’s natural tendency to squirm by encouraging an all-out wiggle-fest. “First wiggle where your tail would be. Then wiggle all your hair. Feeling extra silly? Wiggle in your underwear!” What preschooler or kindergartner can resist responding to Cronin’s silliness? Her energetic and infectious text is set against Scott Menchin’s kinetic illustrations, which features a high-spirited dog and many other squirming, wiggling, flying, buzzing, busy creatures. (Ages 2–5)
