One Inch at a Time, by Alyssa Herrera, is a tender children’s book about developmental progress, disability, and the many ways children communicate, move, and grow. Built around the idea of “inchstones,” it treats a wiggle, blink, sign, step, or brave attempt as an occasion worth noticing. The opening contrast between a caped child taking off and a baby taking their time quickly establishes the book’s generous outlook: each child follows an individual path, and each bit of progress carries meaning.

Herrera’s short, rhyming lines make this picture book easy to share aloud. The repeated “some kids” phrasing creates a reassuring rhythm while introducing speech, gestures, communication aids, mobility equipment, and physical support in language young readers can understand. Phrases such as “almosts,” “not yets,” and “nearlys” give families an encouraging vocabulary for the long stretches between milestones. The text gradually expands from individual achievements to a wider invitation for patience, kindness, and inclusion.

Mayssa Kennouche’s bright, softly textured illustrations carry much of the emotional storytelling. Children appear using wheelchairs, braces, orthotics, medical tubing, signs, sounds, and other forms of communication, surrounded by attentive families, classmates, teachers, and friends. Mobility aids and medical equipment are presented as familiar parts of everyday life. Spacious character vignettes focus attention on small actions, while fuller scenes at the playground, pool, track, classroom, and birthday table show the joy of belonging to a community. The varied faces, bodies, cultures, and abilities give the book’s message real visual substance.

One Inch at a Time offers a cheerful and practical way to talk with children about growth that happens at different speeds and in different forms. Its final pages bring everyone together in celebration, then close with a personal note from the parents of Mack and Mila, grounding the idea of inchstones in lived family experience. Parents, teachers, therapists, and caregivers will find plenty here to begin conversations, but children receive the most important message directly: their efforts matter, their way of growing belongs, and even the tiniest win deserves a cheer.
