Kenadie Jourdin-Bromley Has Primordial Dwarfism, Mom Struggles To Give Her Normal Life

March 8, 2011 — -- Kenadie Jourdin-Bromley is a medical wonder, a tiny girl living in a big world.

She stands 33 inches tall and weighs 17 pounds, roughly the size of an 18-month-old toddler. But Kenadie is 7.

Kenadie has an extremely rare form of dwarfism classified as primordial dwarfism, which means, unlike most little people, Kenadie's head and limbs are also proportionally small, giving her a doll-like appearance.

"It's a really, really big world. It's a really big world around her," her mother, Brianne Jourdin, told "Good Morning America."

The average 7-year-old stands a foot taller and weighs three times as much as Kenadie does. Her brother, Tyran, 5, stands head and shoulders above her.

Doctors predict that Kenadie will never be taller than 3½ feet. That's nearly 2 feet shorter than the average U.S. woman.

Kenadie may never get to womanhood. Indeed, most primordial dwarves do not live past their teens.

She will always face serious medical threats because the bones of primordial dwarfs are very thin, putting them at high risk for breaks. There's also the danger of scoliosis, a curvature of the spine and heart issues.

Perhaps the greatest threat to Kenadie -- one that must be watched her entire life -- is the risk of an aneurysm, a bulge in a blood vessel that can suddenly burst and kill.

She was diagnosed with her condition when she was 8 months old, and has aged prematurely as a result.

"It's concerning not to see anybody over the ages of, you know, 20-something with primordial dwarfism," her mother said.

Unlike other dwarfs, primordial dwarfs have what are considered normal proportions, but their growth is retarded almost from the moment of conception.

Kenadie weighed only 2½ pounds when she was born. She measured just 11 inches. Her hand was as big as a quarter, and her foot was only an inch and a half long.

"I just want to hear her cry. … If she cries, then she's alive," Kenadie's mother said she remembered thinking. "And then we just heard this tiny, tiny little meow."
