In Joyful Memory of Delaney Nalepka
2006–2020
The Foundation is named after a small yellow sticker — Delaney's own act of kindness, returned to her when she needed it most — and opened by her family after she was gone.
Faith ◆ Hope ◆ Joy
The actual sticker — in Delaney's handwriting
Years before she relapsed, while she was battling leukemia, Delaney noticed that her school aide was having a hard day. Without being asked — without any fanfare — she placed a small yellow sticker on her aide's laptop. It was flower-shaped, handwritten, and it said: Don't Worry, Be Happy. The aide kept it. On hard days, she would look at it and think of Delaney.
In October 2020, Delaney relapsed. The aide — knowing this — sat down and wrote her a card. She tucked the sticker inside. Her message was something like: you gave this to me when I was having a bad day and it cheered me up, so I thought I would give it back to you now, when you need it.
The card arrived while Delaney's family was at the hospital. They had been there for weeks after the relapse, with barely any time at home. Mail stacked up. Bills. Cards. Letters from people who loved her.
Delaney never came home.
When her family finally returned, they sat down to open the mail. That card — the one with the sticker inside — was the very first one they opened.
"A small yellow sticker, shaped like a flower. Delaney's own act of kindness, finding its way home to her — and then to her family — at the moment they needed it most."
That is the Don't Worry, Be Happy Foundation. Not just Delaney's spirit, but the way that spirit traveled: from a child fighting cancer, to someone having a bad day, and back again — full circle, still full of love.

"Delaney faced four years of illness with a grace and joy that humbled everyone around her. This foundation is our way of honoring that grace — by standing beside the families who need someone to walk through the darkness with them."

Pediatric cancer doesn't just affect the child who is sick. It consumes entire families — financially, emotionally, and spiritually. We exist to meet them in that darkness.
Families with a child currently in active pediatric cancer treatment — exhausted, afraid, and in desperate need of rest and reconnection.

She fought for four years. She was also — in every possible sense of the word — a light.
Delaney Nalepka was ten years old when she was diagnosed with acute lymphoblastic leukemia in October 2016. She was fourteen years old when she passed away on November 12, 2020 — one month after her cancer relapsed — due to complications from the effects of treatment. She fought for four years.
Delaney never met a stranger. She moved through the world with a kind of effortless generosity, noticing the people around her and finding small, quiet ways to remind them that they mattered. She sang through life. She danced through life. And remarkably, defiantly, she sang and danced through cancer treatment too.
She had a gift for making everyone around her feel seen, loved, and lighter — and she carried that gift with her through four years of treatment without ever letting it dim.

The story behind this foundation's name says everything about who she was.

Every gift carries her spirit forward — to families who need it most.
To honor Delaney's legacy by providing support, hope, peace, and joy to families affected by pediatric cancer and childhood cancer loss.
The Don't Worry, Be Happy Foundation exists to honor Delaney's legacy by providing support, hope, peace, and joy to families affected by pediatric cancer and childhood cancer loss — through financial assistance, compassionate outreach, and meaningful restorative experiences during life's most difficult seasons.
A community where no family facing pediatric cancer — or the loss of a child to cancer — ever feels alone, forgotten, or without hope.
Pediatric cancer doesn't just affect the child who is sick. It consumes families. It disrupts finances, relationships, careers, and emotional health — often for years, and sometimes forever when a child is lost.
Most organizations focus on treatment support, research funding, or public awareness. Those efforts are vital. But there is a quieter need that often goes unmet: the need for families to simply rest. To reconnect. To feel human again during — or after — one of the most dehumanizing experiences imaginable.
The Don't Worry, Be Happy Foundation was built from inside that experience. Its purpose is to look at exhausted, grieving, overwhelmed families and say: You deserve a moment to breathe. We'll take care of everything else.
We begin where we know — building credibility and proven systems before expanding regionally and nationally.
Priority referrals from University Hospitals Rainbow Babies & Children's Hospital. Building trust, capacity, and proven systems.
As funding and operational capacity grow, we expand eligibility regionally and then nationally — reaching every family who needs us.
"No family should walk through the darkest season of their lives alone. We are here to walk beside them — with compassion, with resources, and with hope."
— Her Family
Every dollar, every hour, every shared story moves us closer to a world where no family faces this alone.
Three programs. One purpose: to give families what they need most — rest, relief, and the knowledge that someone cares.
The foundation's signature initiative provides fully funded restorative vacations for families affected by pediatric cancer — both families in active treatment and families who have experienced the loss of a child.
These are not token trips. They are carefully planned, deeply personal experiences designed to give families genuine rest and reconnection without any financial or logistical burden. Every detail is handled by the foundation — so families can simply show up and be present with one another.
The Traveling Physician For any family with a child in active cancer treatment, a qualified physician travels with them. A parent cannot truly rest if they are afraid. By ensuring a physician is present, we give families something most haven't had in years: permission to stop bracing for the worst.
Direct financial support for families facing hardship from pediatric cancer. We help cover medical travel, housing during treatment, utilities, groceries, uncovered medical expenses, and memorial support.
Because survival, in all its forms, has a cost.
Care packages for families in treatment. Hospital visits and bedside presence. Grief support and bereavement check-ins. Faith-based encouragement. Community events that bring affected families together.
Sometimes the most important thing is simply showing up — the way Delaney always did.
Every donation funds real, tangible support for families who are living through the hardest season of their lives.
