Can Seth convince his rainbow friends, that their differences make them better?

Seth wants to build a treehouse home,
however he knows he can’t do it alone.

The Rainbow Monsters help Seth on his way,
but of each other they don’t have a kind thing to say.

Grab a friend, cuddle up, settle down and lets see,
if Seth ends the day, with a house in a tree.

Everyone's raving about Seth and his colourful pals...

"Rainbows and kindness rolled in to one beautifully written story. This is one of the most lovely books I've read to my children in ages. It sends out such a positive message about kindness and that our differences are what make us special and that we shouldn't be afraid that we're not all the same but instead celebrate these qualities. A firm favourite in our house!"

“Spreading kindness through monsters and rainbows. This is an absolute cracker of a book! Not only are the illustrations beautiful, the words and the story will melt your heart. As a teacher I have used this book in class and it is a perfect way to introduce kindness to children. The characters are relatable yet loveable. What Laura has created is a real treasure pot that needs to be used in every classroom. We often stop during class time to share #bemoreseth moments, children get to share kindness stories and it is wonderful to hear them speaking nicely to one another... It's a firm favourite in this house"

Laura Maclennan

Author of Don’t Be Silly! featuring Seth and the Rainbow  Monsters and the upcoming sequal, Don’t Be Scared!

Laura is an experienced teacher, leadership coach, sprinkler of all things positive and magical, and a self-confessed lover of the 80s’ power ballad. When not playing with her children or working, Laura can be found sneaking a bar of chocolate on the stairs or reading in her book nook with a nice cup of tea. Laura grew up experiencing unkindness herself and then went on to teach across the curriculum, particularly drama, and within the Special Educational Needs sector. So she knows only too well how small differences can become large beacons for creating division and sadness. With this in mind, and having had her own children, Laura wanted to create something to teach children from a young age that kindess is stronger than unkindness and has more longevity; that our differences make us better. She also wanted to create a simple reminder of this for children to call upon when needed. With major ‘mam guilt’ because she has already written a book for her daughter, Eliza, Don’t Be Silly! Featuring Seth & the Rainbow Monsters was created for her son, Seth. Written just before rainbows became forever linked to the incredible NHS, the Rainbow Monsters were born, because real Seth is Laura’s ‘rainbow baby’ – the term used for a baby born after a miscarriage or other devastating baby loss. With imaginary Seth and his colourful monster friends, Laura wanted to honour the colour Seth has brought to her world, as well as to bring brightness and kindness to bedtime stories and classrooms everywhere. Laura hopes that the message of Don’t Be Silly! will resonate with all who read it and create a ripple of kindness and acceptance, so that both her children and yours can be exactly who they are born to be, by remembering it’s ok to #bemoreseth.

I’m Laura and I live with this happy twosome and their Dad 🎈a dog and a cat!
Don’t Be Silly! featuring Seth and the Rainbow Monsters is my first children’s picture book and I am ridiculously excited that it is our there, being loved by so many of you!

Don’t Be Scared! will be released in June 2022!


I’ve been a teacher for 18 (🤯) years, qualifying in Secondary Education, before spending over a decade working with children and adults with autism and then running my own Baby Signing business. These days I can be found with Year 2 twice a week, writing and promoting the messages of Don’t Be Silly! and encouraging #bemoreseth action in schools, as far and wide as I can manage.

I’ve always written poems and rhymes but after writing a story for my daughter when she was born, I felt guilty and decided to write one for my son. #mamguilt

So, inspired by my Seth, Book Seth encourages 7 different shaped Rainbow Monsters to ‘Don’t Be Silly’ as they name call each other when they help Seth to build a treehouse. 😔

Seth tells them that our differences can be our strengths and that we can work better, together. 🌈

We’re book lovers in our home, with both kids being read to ‘from scratch’ 😂 I wanted to write something as a gift to each of them but it’s already becoming so much more!! 🤯

Now, I’m passionate about children everywhere being able to read it and understand we all have our place, regardless of appearance or interests! To #bemoreseth and perhaps, one child at a time, create a world with kindness at the core.🤞🏻

Illustrated by the wonderful  Kylie Dixon, Don’t Be Silly! has sold nearly 1000 copies just via word of mouth and social media.


I’m unapologetic in my positive outlook, gratitude and desire for a kinder world. I want everyone to have the opportunity to live their best possible life and shine as bright as they possibly can. ✨

I believe the sooner we can teach our children they have this power within them, the better for our future generations and maybe playgrounds everywhere today.

Thanks for being here! Laura xxx🎈🌈
