It's Fun to Be One

With their spontaneous, unposed air, Pragoff's color photographs celebrate youngsters' growing abilities. An upbeat, minimal text accompanies images of exuberant one-year-olds of many races banging pots, jangling keys, taking first steps and indulging in other toddler-esque behavior. Pragoff's equally chippper two-year-old models exhibit growing sophistication: activities shown here include drawing, building a tower of colored blocks and piecing together a puzzle. Mealtime, too, is a far more dignified affair than the pasta-flinging fest seen in One. Printed on extra-sturdy tear- and bite-resistant paper coated with an easy-to-clean emulsion, these volumes are likely to withstand plenty of enthusiastic handling. Ages 1-4. (Feb.)
