We bought this book to give to our Preschool graduates on Children's Sunday because they question everything and we wanted them to have the answer to the most important question in their young lives. We all love the fact that the questions are asked so much like the way they would ask them and that the answers are so simple. What we like the most, however, is that each answer has a Biblical reference in the back where the parents or teachers can take the children to show them how the Bible answers their questions. We bought these for 4/5 year old, but, my 8 (almost 9) year old son was reading it and he went to his own Bible to look up the answers. What a great tool for children of all ages! This is a great buy! We would all highly recommend it!
