The Very Hungry Caterpillar by Eric Carle Review: A Timeless Picture Book Classic
Eric Carle's children's picture book The Very Hungry Caterpillar has sold more than 50 million copies and been translated into more than 60 languages, earning its place as one of the most enduring works in the picture book canon — a deceptively simple story of metamorphosis that doubles as an early-education tool covering counting, days of the week, and the concept of natural change.
Best for
Parents, caregivers, and gift-givers looking for a first picture book for babies and toddlers who are just beginning to learn counting, days of the week, and sequencing through an irresistibly simple, tactile story.
Worth it if
Worth it if you want a single book that simultaneously functions as a bedtime story and an early-counting lesson — all in a format designed to be physically engaging for very young hands.
Skip if
Skip it if you're looking for longer narrative arcs, complex character development, or content that will hold the interest of children who have already moved past early counting and sequencing.
What readers & critics say
Wikipedia records that the book has sold more than 50 million copies, been translated into more than 60 languages, won numerous awards, and been acclaimed as "one of the greatest childhood classics of all time." The Guardian collected reader tributes after Eric Carle's death in 2021, with caregivers and educators describing the book as a fixture of family life read repeatedly across generations.
“We still read it weekly — while it's worse for wear now, he will be greatly missed but his work will live on through us.”
— The Guardian“The children were entranced — a retired London librarian recalls the book's hold on young readers over decades.”
