Poop Hurts! was written principally for children at the potty-training stage. At this period, many children get constipated because they don't feel comfortable using the potty. "Once a child becomes constipated and has hard and painful stools, he or she will then begin to hold the bowel movements to prevent it from hurting again. This creates a cycle that makes the constipation continue and become worse." The book was created as support for parents with this kind of issue. Steve is an energetic two-year old boy. His excitement causes him many boo-boo's during his play time. In each adventure Steve hurts himself and his own body talks with him and explains his boo-boo's and how important is to take care of himself. On this adventure Steve does not want to listen to his body and gets constipated, a problem that many children suffer when they are potty training.
