Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I bought this book for my daughter for the celebration of the Birth of the Bab and it is so cute! I absolutely love this little book and highly recommend it for a child of any age! My daughter is 9 months and loves when I read it to her.
