Babies may look cute on the outside, but inside is a construction site. The blueprint? A human life! With the crucible of birth behind them, the baby's cells have no time to lose tackling the challenges of life outside the womb. When you're just a few pounds, a bump to the head causes panic, a vaccination is a mysterious invasion, and a mild cold can seem like a five-alarm fire! White Blood Cell has no shortage of enemies to fight, and Red Blood Cell will have to toughen up quick...a growing body is no place for crybabies!
