Very cool children's book. Quirky but a great way to discuss "getting carried away" and being a bit too wild... even pig's granny seems to have had trouble with too much digging. But pig is always part of the group of friends and his friends help him to recognise when he's gone too far without excluding him. Models ways of solving problems without being moralistic. Just funny. There are even some adults who might do well with this book as a present... And for little brothers and sisters there are hundreds of pictures of diggers. What more could you want?
