The Grumble Storm

Name: The Grumble Storm
Author: Atlas Moon

A soothing bedtime story to help children calm big angry feelings and let go.

Ages 3–7AngerBig feelingsSelf-soothingFeelings pass

Mira came home with a stomp and a frown — and a small grey cloud began to grumble. As her anger grows, so does the storm, until thunder fills her little room. Then Lumo glows awake with something every angry kid needs to hear: storms always pass. Together they name the mad, breathe it soft, and let the storm rain itself out — all the way to a clear, starry, sleepy sky.

For Parents

Written for exactly this bedtime.

For the tantrum-prone evenings and the rotten-day bedtimes: The Grumble Storm gives children a picture of what anger feels like — a storm that builds, booms, and always passes — and a simple, repeatable way through it.

The story never shames the mad. Instead it teaches the same cool-down counselors recommend: label the emotion, slow the breath, and ride the wave until it rains itself out. Children learn that feelings come and go, and that they can help a storm pass instead of feeding it.

The book closes with For Grown-Ups: Calming the Grumble Storm — phrases to try mid-meltdown, what anger looks like at ages 3–7, and the storm-watching practice from the story.

Questions

Frequently asked

What ages is this book for?

Written for children ages 3–7 — read-aloud for the youngest, early independent reading at the top of the range.

Will it make tantrums worse by talking about anger?

No — it does the opposite of dwelling. The story gives anger a shape children can watch from a small distance (a grumbly storm), then teaches a concrete way to let it pass. Naming a feeling is the first step of calming it.

Will it scare my child?

No. The Grumble Storm is a small, grumpy-faced cloud — more silly than scary — and the story always ends rained-out, cozy, and ready for sleep.

Is there anything for parents?

Yes — the book ends with For Grown-Ups: Calming the Grumble Storm, with scripts and age-by-age notes.

Is this part of a series?

Yes. Book #2 of the Lumo Bedtime Books — each book helps children with one big feeling. Four are available now.
