I spent a lot of time looking for Brazilian Portuguese childrens books online and managed to find some, however I couldn't determine which Portuguese was featured in this book, on receiving the book the first thing I noticed on the back cover is that it features European Portuguese. Although a lot of words are similar I need to translate the different ones - a small problem since I am learning the language too. Nonetheless my 18 mth old loves this book, its fantastically colourful and really well laid out. He hands it to me everyday to look at the different pictures which are extensive, I'd recommend this book but would love if they came out with a Brazilian Portuguese version. The online pronunciation guide is definitely European Portuguese.
