"In the same way that a baby eagerly learns how to crawl, the cells in a baby's body work just as hard! Food allergies, summer colds... When things are tough for mom and dad, the cells are busy too! As the baby starts to eat baby food and grow bigger, the cells grow steadily. Everyone used to be a baby, and this manga, which represents cells as small children, is dedicated to all of us."--Back cover.
