This book is fantastic! My four year old loved it! We walk around questioning things all the time and it has created a fun thinking game for our whole family. A friend came over and picked it out to read to her children who are 7 and 10. We went to dinner that night and had conversations the whole night on what statements in the newspaper could apply to "maybe yes, maybe no" line of questioning. Then we talked about gossip the children had heard in their school and again went through the "maybe yes, maybe no" line of thinking. It is a great way for children and adults to learn and wake up their critical thinking.
