Valeria Mendoza, where children’s books become emotional tools.

Hi, I’m Valeria.

And even though I write books for children, this story actually began when I became a mom.

More than just books

 Many parents feel they lack the experience to support their child’s emotional development.

You don’t need to be an expert—you just need age-appropriate tools that turn complex ideas into simple, child-friendly language.
That’s exactly what these books are made for.

From the Heart

Becoming a mom taught me that supporting our children’s emotions isn’t always easy… but it is deeply necessary.

My books, The Planet of Joy and The Planet of Sadness, were born from my story with Santi. They’re made to help you connect with your child—with love, without judgment, and with full presence.

Today, I invite you to discover them and use them as a bridge to feel and grow together.

The Planet of Sadness

This book was born after a difficult chapter in my life: my divorce.

I asked myself many times how to talk to my son about it… without hiding it, without sugarcoating it.

The Planet of Sadness is a space where sadness isn’t wrong or uncomfortable—it’s simply part of growing up.

Join Santi and his star on this underwater journey, and discover how love can still be felt—even in the hardest moments.

The Planet of Joy

When my son was little, it moved me to see him so happy that he couldn’t stop.
But sometimes, that overflow of joy also came with exhaustion, impulsiveness, and frustration.
The Planet of Joy is a story about just that. About how even joy needs space, guidance, and gentle support.

It’s a heartwarming adventure that helps children recognize and navigate big feelings—both the happy and the challenging ones.
Now available in both English and Spanish, more children can see themselves in the story and identify with what they feel.

Activity Book – The Planet of Joy

In this interactive version of The Planet of Joy, children don’t just read — they play and participate! Through fun activities, and thoughtful prompts, little ones get to explore what makes them feel truly joyful. It’s a beautiful way to spark conversations about happiness and strengthen the bond with their grown-ups.

Activity Book – The Planet of Sadness

This book was created as a gentle companion for sad days. It includes breathing exercises, coloring pages, and simple tools to help children express what they’re feeling. It’s an invitation to honor sadness, walk through it with love, and open space for talking about what hurts… and what helps.

Stories and Emotions: My Why

Hi! I’m Valeria, a mom who discovered in storytelling a way to connect with emotions.

My journey as an author began when my son Santiago was born.

Becoming his mom brought me face to face with a powerful truth: we don’t always know how to support what our children are feeling… and sometimes, we don’t even know how to support what we are feeling.

A look inside the books:

The Planet of Sadness

The Planet of Sadness is a place that offers support and hope. We are here for you with open arms to lovingly help you cope.

Just going to some special place can change your feelings at that time and take your thoughts to somewhere else where you can have some peace of mind.

The books they read today become the tools they’ll rely on tomorrow.

Children aren't too young to learn about their emotions. It's part of healthy parenting!
