My two daughters loooooove the Fancy Nancy series as I do! I love the way Jane O'Connor has incorporated into each book "fancy" words along with what they mean (Jane O'Connor gets a 10 in my book!). My children love the stories (which are also educational) along with learning the "fancy" words throughout the story. My children speak well for their ages (now 6 and 10 but were introducted to Fancy Nancy at 4 or 5) and I'd like to give some credit to Jane O'Connor's Fancy Nancy books for that. I love the character Fancy Nancy as well - she is soo cute and portrayed as a child who always means well. Credit also goes to the illustrator, Robin Preiss Glasser who does a fabulous job portraying Fancy Nancy!
