Written from Jessie's perspective, this book explains and educates her classmates about her condition. Jessie explains to her classmates what cystic fibrosis is and tells them that it feels like "elephants dancing on her chest". She has to cough a lot, but she explains how it actually helps her. Jessie shows the class how her parents help her to keep her lungs clear. Designed to help kids better understand their classmates with cystic fibrosis, this brightly illustrated picture book also educates families, teachers, school nurses, parents, and caregivers.
