Meet Messy M'Cheany—when it comes to a mess, this kid is the best! However, as soon as Messy meets his new baby sister, Missy, he realizes that she does not share the same fondness for messes, but instead loves to be clean! How will he learn to get along with a sister who is so different? Kathy Lee Gifford's new rhyming picture book teaches children that though being messy is fun, changing bad habits for baby sisters and brothers is the best thing any sibling can do!
