Despite the negative reviews I have (4,5 months) bought my daughter the fabric storybook. Especially important to me was the good performance of the book in the test of the magazine Ökotest (overall rating of "very good" test result ingredients "good"). Only two other books have achieved this result. On the subject of sound, I would add that the cow pendant rattles and that this fully in my opinion sufficient. I think it is totally nonsensical educational when young children are already "on the bell". The partly unrealistic depictions of animals are the perception of babies (up to about 6/7 months) meet (animals have relatively large heads and are shown in bright colors). My daughter is preparing the book a lot of fun, you can invent great little stories around the to-find on each side chick. And just as a purpose was supposed to meet such a book?
