In My Heart, Reviewed: The Big-Feelings Book That Actually Gives Kids the Words

Here is what usually happens when you buy a feelings book: you read it once, feel like a good parent, slide it onto the shelf, and your child requests the dinosaur one instead. Most feelings books are written for the parent who wants to do something, not for the child who is in the middle of something big. In My Heart is one of the few exceptions. Here is what it does, and what makes it work.

What is In My Heart actually about?

Written by Jo Witek, illustrated by Christine Roussey, In My Heart takes young children through ten emotions: happiness, sadness, bravery, anger, shyness, love, jealousy, disappointment, calm, and scared. Each gets a two-page spread and a short, sensory description of what that feeling is like inside the body.

The physical design is what most reviews mention first, and rightly so. Each page has a die-cut heart in the upper corner that shifts in size with the emotion. Happiness has a big, full heart. Sadness has a small, heavy one. The shape actually changes as you turn pages, which gives young children something concrete to follow as the abstract words settle.

Ages on the cover say 2 to 6. In practice it works best between 3 and 5, when a child can point at something and say “that one” but does not yet have the language to explain why.

Why naming a feeling is the whole point

Labeling an emotion reduces activity in the amygdala, the part of the brain that processes fear and stress. Researchers at UCLA, led by Matthew Lieberman, showed this in a 2007 study: putting a feeling into words creates just enough cognitive distance to make it more manageable. It is the mechanism behind what Dr. Dan Siegel calls “name it to tame it” in his work on the developing brain.

In My Heart builds that vocabulary without requiring a parent to explain neuroscience over the dinner table. The language is simple but not thin. “Sadness feels heavy, like rain on a grey day.” “Anger is too loud for one body.” The illustrator does a lot of work too: each child in the book shows the feeling in their posture, not just their face, because young children read emotion in the body before they read it in the eyes.

The part that actually works

The book does not rush past the feeling. Each emotion sits on the page, fully acknowledged. Anger is loud and hot and entirely valid. There is no sentence after it that says “and here is what to do instead.” That restraint is rare, and it sends a message to a young child that the feeling itself is acceptable, not just the managed version of it.

One of my children was going through a volatile patch around age four. This was the first book where he pointed at the page and said, “That is what I feel right now.” Not at the illustration. At the word. He had found his word. That is the entire thing feelings books keep trying to do, and mostly fail at, because they explain feelings at children instead of handing children the language.

Where it falls short

After the twentieth read, and it will be the twentieth because children are relentless, the text starts to feel thin. Each emotion description is evocative but brief, and there is no narrative thread running through the book. A few feelings (jealousy, disappointment) get descriptions that are more poetic than precise, which is beautiful once and then a little slippery every time after.

It is also a read-aloud-with-an-adult book. It was not designed for independent reading by a four-year-old, which is fine, but worth knowing before you hand it over and walk away. And by the time a child can hold a real conversation about their inner life, they have probably outgrown it. That happens somewhere around 6 or 7 for most kids.

None of that makes it a bad book. It makes it a well-aimed one. You are buying it for a window of time, and within that window it earns its place entirely.

Who should actually get this

If you have a child between 3 and 5 who shuts down when upset, or who hits or bites because they do not yet have the word for what they are feeling, this book is worth the shelf space. Read it during calm moments, not in the middle of a meltdown. The point is to build the vocabulary in advance so it is there when you need it.

If your child is already talking about their feelings in full sentences, or is closer to 6 or 7, it may feel too simple. There are books that go deeper. The Colour Monster by Anna Llenas is a strong alternative for 2-to-4 year olds that uses colour-coding rather than die-cut hearts. For children dealing specifically with anxiety, Hey Warrior by Karen Young is where we would point you first.

What parents and experts say

Across Goodreads and Amazon, In My Heart holds a 4.8-star average from thousands of families. The pattern in the most helpful reviews is consistent: a child who previously expressed frustration only through screaming now pointing to the anger page and saying, “That is me.” Occupational therapists and child psychologists list it consistently among their first recommendations for emotional vocabulary at this age, particularly for children with sensory processing differences. If the feelings are clustering specifically around nighttime fear, this piece on bedtime anxiety covers what is usually behind it.

It has also found steady use in early childhood classrooms and therapy rooms. Books that make it into the hands of professionals tend to be the ones that do not talk down to children. This one does not.
