These have been favorites of my kids for the last few years. My daughter knew all the words by the time she was 3 because we read it to her just about every night. Now she is 8 and will sit with me while I read it to my two year old son, who also already knows all the words. They hold up well and after 8 years are in still very good condition despite being constantly read. You can not go wrong with these easy great stories. I have purchased every book from this author and have gotten every penny out of them. I am sure my kids will be reading them to their kids at some point.
