To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. I bought this as a Christmas present for my nephew because at 2 years old, he hasn't shown much interest in books (even for the pictures), but responds to anything noisy! I felt they enhanced the story quite nicely, although a lot of people seem to be saying they found it distracting.

The book looks thick but the back part doesn’t have pages as I gather this is where the battery fits. As this is my favourite children's book of the day, I just had to get it for him and I thought it was the perfect introduction to books and story telling. This is a fab book for young children; the story is lovely, and the sound buttons are a great way of involving the child in the story-telling process. The ideal gift for all Gruffalo fans, The Gruffalo Sound Book is also the perfect introduction to this family favourite .The sound buttons are a bit harder to press than other sound books and my son often needs help to press hard enough.

Pages inside the book are paper rather than being a board book throughout so can be easily ripped by an enthusiastic toddler! I was a little disappointed as it only makes noises of the animals when the music notes are pushed I find it hard to push never mind a four year old. I loved this addition, as did my 3yr old son, as it introduces an interactive element to story time and promotes active listening.
