Book cover of Peanut Butter & Cupcake

Carolyn Watson-Dubisch Author Of The Elephant and The Teapot are Friends

From my list on unlikely friendships for small children.

Why am I passionate about this?

As a children’s book author, a parent and a teacher for small children, one of the greatest things about children’s media is the friendships that develop among some of the most unusual characters. Like a sea sponge and a starfish in SpongeBob Squarepants, a mouse, and a dog with Mickey Mouse and Pluto. This of course extends into children’s books and it’s an extension of how young children don’t concern themselves with how different the other person is, they focus on what is the same. Something people should hold onto as they grow but often don’t. 

Carolyn's book list on unlikely friendships for small children

Carolyn Watson-Dubisch Why Carolyn loves this book

Peanut Butter has just moved to town and is searching for a friend to play ball with. He talks about Hamburger, Soup, French Fries, and Cupcake, but they are all too busy. Finally, he meets Jelly, and of course, they click and play ball. Before long, all the others see them playing and want to join in. In no time, Peanut Butter has all the friends he could want.

The story is so charming, but what really makes this book shine is the art. Terry Border is an American artist known for his unique, funny, and really creative sculptures, often of food, using wire and other materials. The art creates such a wonderful and engaging book. My students absolutely loved this book.

What is this book about?

For fans of The Day the Crayons Quit, Little Pea, or How Are You Peeling?

What’s a little piece of bread to do when he’s feeling lonely? Find a friend, of course!

And that’s exactly what Peanut Butter tries to do. But sometimes friends are hard to come by, especially when Hamburger has to walk his (hot) dogs, Cupcake is too busy building castles in her sprinkle box, and Egg laughs so hard he starts to crack up! Does Peanut Butter have a soulmate? Young readers will know the answer long before Peanut Butter does and laugh along with each…

Butternut is excited that the Spring Plant Show has come to the supermarket where he lives. It’s being performed outside and features the “Flying Butter’, but poor Butternut is terrified of the sliding glass doors! With some help from his many friends, Blueberries, Star fruit, Dragon fruit, and Buttercup, they devise a plan to get through the doors together so no one gets squashed. The illustrations by Anusha Santosh are bright and colorful, and the art embraces a decorative design aesthetic that is perfect for this story. 

The imaginative storytelling of all these friends who are so different from each other really strikes a chord. It’s one reason I am always drawn to the Butternut series of books to share with my students. This one holds up to the rest and brings Butternut and his friends on an adventure and has them working together to solve a problem and reach…

Carolyn's book list on unlikely friendships for small children

Carolyn Watson-Dubisch Why Carolyn loves this book

A little blue jay named Simon is off to find the menacing dragon. The rhyming text is excellent in this story. I love how Simon donned a bottle cap on his head to wear as a helmet. He flies through the forest and asks the rabbit, the ladybug, and finally, the wise owl where to find this scary dragon.

Ultimately, Simon's search finds him a new friend, and he’s not at all what he expected. The underlying message is to not always believe what you hear. The art by Vitali Dudarenka is beautifully drawn and rendered in a classical style. A lovely gift for the child in your life.

Whispers around the treehouse have this birdy buggin’. Can he flap away the confusion and put an end to the mystery?

Simon is determined to find the facts for himself. Tired of hearing endless rumors about a dragon menacing the farm, the young bird munches some breakfast and sets out for answers. And with his trusty bottle-cap helmet keeping his head safe, nothing can stop him from finding the fire-breathing beastie.

Confused by his barnyard buddies’ claims that no one has ever seen such a mighty creature, Simon refuses to give up on his tireless search. But when the truth…

A charming book about a stick and stone who become friends. Told with very simple language we follow the story of Stone from when he was alone to being teased by Pinecone and having Stick stand up for him (because that’s what sticks do!). They play and go on adventures to the shore when a big hurricane sweeps them away, and Stone must save his best friend, Stick!

The illustrations are wonderfully crafted in colored pencil and watercolor. This is a beautifully done book that works extremely well in storytimes with small children. My class loves this one.

In this fun board book about kindness and friendship, Stick and Stone join George and Martha, Frog and Toad, and Elephant and Piggie as some of the greatest friend duos in children's literature.


Book cover of Can I Play Too?

Andrew Wald Author Of A Surprising Friendship

From my list on friendship and diversity.

Why am I passionate about this?

I am a psychotherapist working with individuals and couples since 1974 and have had over 57,000 sessions. How people relate to one another has been a fascination of mine since I was a youngster growing up in a suburb of Chicago. I believe that we are “wired” for relationships of all kinds and it takes a conscious effort to see the best in each other for them to thrive. Differences can be the spice of a relationship, not the division of them. My book, my practice, and my life focuses on those concepts. In 2012, I co-authored a popular book on relationships, Togetherness: Creating and Deepening Sustainable Love.

Andrew's book list on friendship and diversity

Andrew Wald Why Andrew loves this book

This simple, sweet, picture book, like others in the Elephant and Piggy series, deals with different animals who are trying to solve a problem together. I liked the book because it portrays how differences don’t matter when you care about another. To show how differences can be overcome and not be reasons to divide is wonderful, especially when the concept is shown to the very young reader.

Book cover of Circle Round

Nancy Loewen Author Of The Everybody Club

From my list on that create a sense of belonging.

Why am I passionate about this?

I’ve published many books for children, but this one is truly special. The Everybody Club is a collaboration with my dear friend Linda Hayen in memory of her daughter, Carissa. As a child, Carissa started a real-life Everybody Club. The first members were toys, dolls, the family cat, and her brothers, one of whom had severe disabilities. Carissa died in a car accident at the age of 16, and this book is Linda’s way of sharing her daughter’s generous spirit with the world. A note for adults at the end of the book shares this backstory.

Nancy Loewen Why Nancy loves this book

What can a circle be? It can be a ball, a bike tire, a bubble, a cookie, a balloon… A circle can also be people joined together in the spirit of love and acceptance. Circle Round has few words, but the illustrations pull readers into a world full of activity and fun. It’s a counting book that is both playful and profound. 

At the end of the book, I felt I was part of the circle myself.

Counting from one to ten, a growing circle of children see new faces outside the group and invite them over. Children of different abilities, ages, genders, and races demonstrate how easy it can be to expand your group, extend yourself, and welcome new friends.

A monster goes to Pete’s house with the intention to eat him. Pete asks the monster to play with various games and toys. The monster reluctantly does so, but each time the text goes, “He didn’t want to play...because he wanted to...EAT PETE!” Then something shocking happens – he eats Pete!

But Pete has other ideas. And they are all good fun and quite distracting--things like playing cars and pirates. Well, we all know the course of playing together nicely never did run smoothly. So how much longer will…

Kim Hudson Author Of The Bridge: Connecting The Powers of Linear and Circular Thinking

From my list on decoding the mystery of everyday thinking.

Why am I passionate about this?

I grew up in the 70s when a linear perspective was king, including the objectivity of science and elevation of the importance of men’s work, so I fought to become a female exploration geologist. I learned to conquer dangers and collect data to discover riches. I also learned that my feminine intuition and curiosity were invaluable in understanding the patterns in nature. My next career as a treaty negotiator for the Federal government introduced me to indigenous cultures, and I felt the familiar clash of circular and linear thinking once again. I dedicated myself to the study and work experience that would help me give language to this pattern.

Kim Hudson Why Kim loves this book

I was waking up each day feeling the dogs nipping at my heels to keep me running and making progress. When I discovered this book, I felt a sigh of relief. I stayed in the moment and explored the value of play with this delightful and curious guide. 

I couldn’t stop sharing Brown’s stories of how important and marvelous play is. I discovered lots of my friends were as hungry as I was for this other world where we could have fun, without thoughts of time and productivity, and it was actually scientifically proven to be important and beneficial for us (being scientists we needed this fascinating link). I started to seek the vacation in my life, which is such a gift.

What is this book about?

From a leading expert, a groundbreaking book on the science of play, and its essential role in fueling our happiness and intelligence throughout our lives

We've all seen the happiness on the face of a child while playing in the school yard. Or the blissful abandon of a golden retriever racing across a lawn. This is the joy of play. By definition, play is purposeless, all-consuming, and fun. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. We are designed by nature to flourish…

Susie Finkbeiner Author Of The All-American

From my list on making you fall in love with baseball.

Why am I passionate about this?

I’m intrigued by baseball. The passion and drama of the games and the way the sport is nearly always linked to a meaningful relationship with someone dear. That curiosity has only been fueled by the books I’ve read over the years and inspired me to write a baseball story of my own. The All-American is my ninth novel and I couldn’t feel more privileged to have been able to write it.

Richard Scrimger Author Of At the Speed of Gus

From my list on neurodivergent voices, quirky, heartbreaking.

Why am I passionate about this?

I can’t count the number of conversations where I’ve been asked to slow down, or take a breath, or talk in a straight line. My neurodivergent heroes are versions of me: me if I were an alien, or a dying old lady, or a zombie. Gus is the closest I’ve come yet to writing my true self. He’s just me. I want readers who identify with Gus to feel seen and accepted and those who don’t—to understand what it’s like to live like this. And, just maybe, to have a little fun along the way.

Richard Scrimger Why Richard loves this book

Tom is the hero we need today. I love characters who know who they are and don’t care what others think of them. And I value ‘fun’ as a goal.

Tom just wants to fool around and yawns at his aunt’s disapproval. The contests between Tom and his aunt’s champion, Captain Najork, are the best descriptions of games I’ve ever read, especially when you consider that the games themselves are invented out of whole cloth and the words applied seemingly at random.

So the Captain challenges Tom to three rounds of womble, muck, and sneedball, certain that he will win. However, when it comes to fooling around, Tom doesn't fool around, and his skills prove so polished that the results of the contest are completely unexpected...
