Join Bing on a toilet training adventure in this interactive sound book – perfect for encouraging young children to use the toilet with confidence. Bing doesn't use his potty anymore – he uses the big toilet, and you can too! It can be scary at first, but with a little practise you'll be catching the Toilet Train in no time. Bingsters will love pressing the sound icon and joining in the fun. Choo! Choo! Catching the toilet train. . . it's a Bing thing!
