Great book and opportunity to learn two languages!
Format: Hardcover
My five year olds have recently developed an interest in the Spanish language. We already have the English version so I now read both to my girls (and also translate the Spanish book when reading). They really enjoy it and I am getting to brush up on the Spanish I haven't used since high school. The pages are illustrated nicely and although the translation is slightly different, it tells the basic story and you can follow along in the English book.
I recommend this item.
