Sibby

Sibylle Eleanor Patrick

Our first Toddler Mobility Trainer went home with a very determined four year old. This is her story, told by the person who knows it best.

Sibby's TMT is Frozen themed: snowflake wheels, royal blue, and a lot of sparkle. So this page is too.

Meet Sibby

Sibylle Eleanor Patrick, but everyone knows her as Sibby

Sibby has two big brothers, Emmett and Nolan, who absolutely adore her. She is happy, sassy, loving, determined, and incredibly expressive. She experiences the world differently than most children, but she has no trouble letting people know what she likes, what she does not like, and exactly how she feels about it.

She loves music, being outside, bubbles, swimming, and especially her brothers. She has the sweetest smile, the best giggle, and a personality that can light up a room.

In her mother's words Sibby's story, told by her mom Written by Jen Patrick, August 2026. Condensed, about a five minute read.

Our family has learned to appreciate moments that might otherwise be easy to overlook: hearing Sibby laugh, watching her enjoy the breeze on a summer day, seeing her splash in the pool, or watching the excitement on her face when she is surrounded by the people she loves. Those moments mean everything to us.

Our journey with SCN8A

Sibby was born in August 2022. Every prenatal test and scan gave every indication that we were expecting another healthy baby. By the spring, though, we knew something was not right. On April 12, 2023, we brought her to the Johns Hopkins emergency department after seeing an unusual episode. Her head suddenly twitched, her eyes opened wide, her arms shot out from her sides, and she cried in fear afterward. Then it happened again. And again.

Doctors diagnosed her with infantile spasms. At the worst point, we estimated 50 to 60 seizure clusters in a single day. What followed was more than a year of specialists, hospital visits, testing, medications, therapies, and uncertainty. Eventually, a second opinion at Children's Hospital of Philadelphia gave us an answer: SCN8A-related disorder. As far as we know, Sibby is currently the only known individual with her exact genetic variant.

Having an extraordinarily rare diagnosis means there is not always a roadmap. There is no book that tells us exactly what Sibby's future will look like.

“We have had to learn to stop measuring Sibby against what children are supposed to be doing, and instead celebrate what Sibby is doing.”

Why mobility matters

For many families, a wheelchair might initially look like a symbol of limitation. For us, it means almost the exact opposite. A wheelchair represents access, participation, comfort, independence, and opportunity. It allows the world to come to her eye level rather than requiring her to always be carried or positioned separately.

Sibby recently received her first custom medical wheelchair. We chose hot pink, because obviously every girl needs a Barbie Dream Car. But as wonderful and necessary as it is, we also wanted Sibby to have other options, something lighter and easier to take into places where a large medical wheelchair may not always be practical.

Finding MakeGood and EcoPrint

Our introduction to MakeGood happened almost completely by accident. At an end of the year celebration at Sibby's school, I overheard one of her therapists talking with another child's parents about the mobility devices they were providing for children. I was not even part of the conversation. But I was listening. And like so many things on this journey, a conversation we were not originally part of suddenly opened another door for Sibby.

We applied through MakeGood and were thrilled when EcoPrint reached out and told us they had claimed Sibby's build. From that very first message, it was obvious that they did not simply want to manufacture a TMT and send it to us. They wanted to build Sibby's TMT. And there is an important difference between those two things.

Designing something for Sibby

One of the first questions EcoPrint asked was what colors and themes Sibby might enjoy. Frozen immediately came to mind, and we suggested royal blue, light blue, white, and silver. But as the conversation continued, they did something we really appreciated. They started asking questions about how Sibby experiences the world.

In addition to her developmental disability, Sibby has cortical visual impairment, or CVI. Because of the way her brain processes visual information, she may not recognize a character the same way another child might. What she does respond to are bright, bold colors, strong contrast, simple visual elements, and things that sparkle or shimmer. EcoPrint's response was essentially: we will figure out how to make that work. And they did.

“They were no longer simply decorating a mobility device around a theme. They were designing it around Sibby.”

Watching it come together

They brought us along for the build. They messaged us when they ordered the filament and when printing began. Forty percent printed. Almost finished. Ready for assembly. They even created a small scale replica of Sibby's TMT so they could show us ideas for the wheels before committing. Eventually we gave perhaps the least helpful design direction possible: honestly, surprise us. By that point, we trusted them.

Parents of medically complex children spend an incredible amount of their lives navigating systems: insurance companies, equipment vendors, authorizations, denials, approvals, and then usually a few more follow ups. Sometimes even obtaining something your child unquestionably needs can feel like a second job. This felt completely different. What impressed us most was how quickly the conversation changed from what should this TMT look like, to who is Sibby and how do we make this special for her.

The delivery

Rather than simply arranging a handoff, EcoPrint wanted the experience to happen somewhere our family could actually enjoy the device together. Together we chose Annie's Playground in Fallston, Maryland. Let Sibby enjoy her new TMT. Let Emmett and Nolan push their sister around. And capture our family doing exactly what we hope this device will make easier for us to do: experience things together.

That approach meant something to us, because it recognized an important truth about adaptive equipment. The purpose of the equipment is not the equipment itself. The purpose is everything the equipment makes possible. It is not about where Sibby cannot go. It is about all the places she can go.

Thank you for listening when we explained not simply what Sibby likes, but how she sees the world. Thank you for recognizing that snowflakes, sparkles, colors, and a little bit of personality really do matter.

The whole letter

We asked Jen to tell it in her own words

She sent back far more than we expected. What you read above is the condensed version. The whole letter, at her pace, is here.

What happens next

There is another family already waiting

Sibby's build is finished. The queue behind her is not. Three ways to move it along.

One

Fund the next build

Our hours are volunteered and the files are free. What we buy is plastic and hardware. Gifts routed to EcoPrint through MakeGood go straight into the next device.

$200 covers one complete device

Sponsor a device

Two

Build one yourself

If you own a printer, you are most of the way there. The Toddler Mobility Trainer files are open on MakerWorld, the same ones we printed for Sibby.

Files are open and free to use

Three

Know a family like hers

Jen found out about the TMT by overhearing a conversation at school. Most families never hear about it at all. Eligibility comes down to a sizing chart, and there is no cost and no insurance involved at any point.

No cost to the family, ever
