Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Such a well written book with all the hot tips for a Mum to be without the dullness of the old fashion mum books. Bec is honest, yet non judgmental, encouraging and helpful. This book is light hearted, fun and has given me a lot more confidence to being a mum. Thank you
