21 Years: A 21-Year Letter Writing Keepsake Book for Your Child

A simple but powerful tradition, write your child a letter every year for 21 years

Some gifts are opened once.

Others are built over time.

The 21 Years Keepsake Book is designed to become a tradition you return to every year, writing your child a letter on their birthday and capturing the moments that matter most along the way.

Start from birth, or any age, and create a meaningful yearly ritual that grows alongside your child.

What makes this special?

This is more than a memory book. It is a time capsule of your child’s life, built one year at a time.

Each year includes space for:

• Photos and memories from the year
• Favourite things, milestones, and proud moments
• A full page to write a heartfelt birthday letter

Over time, these pages come together to tell the story of your child growing up, in your own words.

A gift they receive on their 21st

What begins as a simple yearly ritual becomes something far more meaningful.

On their 21st birthday, this book is given as a complete collection of letters and memories, something they can read, keep, and treasure for the rest of their life.

It is a gift that grows in value every single year.

Designed to grow with your child

You can start at any age and build the tradition in a way that suits your family.

Each year builds on the last, creating a complete record of:

• Growth and personality
• Milestones and memories
• The relationship you share

There is no pressure to do it perfectly, just to return to it each year.
