My 3 year old son really likes Frog and Toad Card as the story is simple and easy for him to understand. I also find it helpful when I first read the book for him and then he can listen to the card by himself. I am wondering whether there are other Yoto Cards like the Frog and Toad, which have the same content from the books so that we can read books first and then listen to Yoto. The Frog and Toad Card is really nice!
