What a great book - My two and a half year old daughter went back to wetting pants again so I bought this book and it has worked a treat. Enjoyable to read, interesting and of course the cheers that you hear when pressing the button just make this book so much better than just reading text. I even grabbed the book and pressed the button when she used the potty and she was so proud that princess polly was cheering!! The book also covers that the baby in the family is the only one wearing nappies at the moment, this too has really helped because my daughter wanted to be like our 6 month old baby and wear nappies. Highly recommend this book.
