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.
I ordered this for my 5yo who is just learning to read, (it reminds me of Billy blue hat/Roger Red hat that I started with when I was younger) there are only 4/5 words at most on each page and repeats key words i.e vet as this one is about vets, cat, dog ect encouraging word recognition. The barbie theme is also a winner. I will probably order some more,great to start off with.
