You can leave me a comment below and let me know if you agree! The book was published in 2009, so maybe you're familiar with it already.

Author: Beth Cadena
Illustrator: Frank W. Dormer
Publisher: Clarion Books, 2009
Intended ages: 4-8
Themes: Older sibling, helpfulness
Opening Line: "Supersister bounds out of bed. Another super day.
Hark! A call from the kitchen. Mother is in need."
Synopsis: Told in a tongue-in-cheek manner, a young girl helps out at work and school taking on the role of Supersister. The illustrations show close-up shots of Mother's feet, and a head shot from a distance, but it isn't until the third spread from the end that we learn the reason Supersister is being so helpful.
Why I like this Book: The illustrator wrote and illustrated one of my favorite books, The Obstinate Pen. There's a lot of energy in his spare drawings. While there is humor in the book, the book doesn't go over-the-top in terms of how Supersister helps. Moments of getting dressed, getting her own breakfast, and being a good student at school take on super importance.These behaviors are all things a reader can emulate. Despite being a book with an obvious message, the author uses fun language so it doesn't come across preachy or hokey. I especially loved the moments when Supersister lets us know that superheroes are kids, too (and vice versa!) and checks if Mom is watching and listening.
Resources: DON'T READ THIS IF YOU DON'T WANT A SPOILER
The baby that is going to make Supersister a sister hasn't been born yet.
There are many websites to help prepare children for the arrival of a new sibling. The Baby Center and the What to Expect websites have practical information for expectant families.
Read Kevin Henke's classic picture book Julius, the Baby of the World and compare that story and its main character with Supersister. Talk about how people react differently to changes.
Websites with fun activities for older siblings while waiting for baby describes activities like helping to decorate the nursery and acting as family photographer.
