I bought this book for his birthday and he's listened to it several times. He loves turning the pages along with it, trying to pick out the words. This has bled over to some old records I found on eBay including Poky Little Puppy that he loves to listen and read along with.
The only problems I have with this CD/book combo is the CD. As mentioned above, the whole book is a single track. Sometimes the boy wants to hear the same poem again, and the publishers appeared to have anticipated this somewhat as indicated by each page read/sung twice before "bing-ing" to turn the page. Had it been split into individual tracks I think he would listen to it more often.
Still, we love our Peppa book, and I've just discovered there are a whole lot more books available. It is such an age and learning level appropriate series, and the books I think are an excellent tool that will encourage beginning readers. Peppa is geared to children under 6, so I encourage parents of this age group to seek it out.
