Declan Nathaniel Sisson was born on March 9, 2021.

From the very beginning, he carried a light within him — one that sparkled through his laughter, through the way he explored the world, through the way he loved.

He was the kind of child whose presence softened the air around him.
The kind whose smile could melt away even the heaviest day.

Declan wasn’t loud or demanding.
He was gentle, curious, and endlessly kind — a little boy who seemed to notice beauty where others might overlook it.

The moon hanging low above the trees.
A crooked stick found in the backyard.
A passing garbage truck, its engine rumbling like music to his ears.

He loved life with a quiet, radiant joy.

And the world loved him right back.

🌙 A Battle No Child Should Face

At a very young age, Declan’s family received news that would change everything.
Cancer.

It’s a word no parent should ever have to hear.

And yet, somehow, that word became part of Declan’s story — not once, but four times.

Four separate battles.
Four times his tiny body was asked to fight.

Four times he rose with courage that seemed far beyond his years.

He endured four bone marrow transplants.
He participated in three clinical trials, helping researchers learn, helping other children who would one day walk the same painful path.

Through every needle, every surgery, every hospital stay, Declan met the world with grace.

There were tears, yes — but there was also laughter.
There were moments of fear — but far more moments of light.

His doctors often said there was something remarkable about him.

Something that made even the hardest days on the ward feel softer.
That something was Declan himself.

☀️ The Color of His Heart

If Declan could be summed up in a single color, it would be yellow.

He adored it in every shade — from the golden glow of sunshine to the soft hue of dandelions, to the bright shine of a school bus.
Yellow matched him perfectly.

It was the color of warmth, of life, of hope.
And Declan was all those things.

He found wonder in everything — in the way the wind rustled the grass, in the smell of fresh bacon on Sunday mornings, in the soft pages of his favorite books.

He loved reading Little Bear, making art, exploring the outdoors, and snuggling close to his mama and daddy — the place where he felt most safe, most loved.

He owned a pair of Cow & Pig socks that he wore proudly and often, a little detail that made everyone smile.

They became part of his charm, part of what made him uniquely Declan.

Even when hospital walls surrounded him, he carried joy like a lantern.
He would greet nurses with giggles, point excitedly at pictures, and talk about the things he loved most — garbage trucks, farm animals, and the moon.

He reminded everyone that even in pain, there is still beauty.

💛 The Final Chapter, The Eternal Light

On June 9, 2025, Declan’s battle came to an end.
His tiny body, tired from years of fighting, was finally at peace.

He slipped gently into eternity, surrounded by love so deep it could fill the stars.

He was only four years old.
Four years — and yet, he changed more hearts than most do in a lifetime.

Those who knew him still speak of his laughter, his courage, and his yellow spirit that never faded.
He taught them to look for light, even in darkness.

To live with gratitude, even when life feels unfair.

To notice the small miracles — the color of the sky, the warmth of a hug, the sound of laughter echoing down a hallway.

Declan’s story is not one of loss, but of legacy.

He gave more than he ever took.
He left behind a trail of sunshine, a thousand moments of joy, and a reminder that even the smallest souls can carry infinite light.

In every sunrise, in every dandelion carried by the wind, in every child’s laughter that rings through the air — Declan is there.
His love still glows.

His spirit still shines.

He was — and always will be — the brightest yellow.
