My 12 mo LOVES your range of books that play music and make noises. I also think your books are great value for money and the online ordering was great- I received my books within 48 hours. My only suggestion would be that you also sell the correct batteries for your books (I see you have a page for it on your site but nothing listed there). I've bought two lots of batteries from Amazon for the various books but none seem to fit properly despite following the type on the back of the battery box on the books (we've previously had books as presents so my recent order was all replacements for ones which have worn batteries).
