Even when a baby turns over in bed, there are many cells working hard behind the scenes to make it happen! This second volume of the manga featuring anthropomorphized cells working in a baby's body is dedicated to all the busy moms and dads out there, as well as everybody else who was all once babies! Even after a baby is safely born, they'll bump their head, get vaccinated, and catch a cold... There's just never a moment of rest for the cells in a baby's body!!
