Superb book on the human body. Pulls all of that amuse children A specific page or the baby is seen moving in water as in the belly of her mother Simple explanations of all topics related to the body (birth, teeth and cavities, moments of life (birth, baby, child, adult, old age ...), skeleton, muscles, brain, organs, girl / boy ... ) Simple easy to understand explanations. From 3 to 4 years in my opinion.
