To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
My daughter is 4 years old and is Autistic. The protruding features of each animal really stimulates her interest. The repetiveness of the playful, descriptive words are wonderful and the images are drawn well. This is a book she carried with her constantly for two weeks!
