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 analyses reviews to verify trustworthiness.
This was disappointing. After looking it over I decided to return it rather than give it to my grandsons. I'm surprised at how hard it seems to be to come up with a good new children's book. Also, must so many children's books focus on "time to go to bed now"? There are other reasons to read besides putting someone to sleep.
