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.
This was recommended as a good book to encourage positive conversations about different types of bodies. It has loads of pictures of people with various interesting differences of the kind that could be pointed out and commented on by a four year old child. Birthmarks, scars, soft middle aged bellies, prosthetic limbs, glasses, tall, short, different races, hair in different places. But I just found it missed the mark. Aside from stating that "bodies are cool", they don't really show how cool bodies are. or bring out any of the amazing things bodies can do. There is one page where we see people in a ballet class, but that is the only page where we see a body actually doing anything other than standing around. I don't enjoy reading this to my son, and I think I will have a go at doing better myself.
