Toddler with rare genetic disorder is not letting his stroller hold him back

News24xx.com -  A 1-year-old boy diagnosed at birth with a rare genetic disorder isn't letting his stroller to hold him back.

Josiah Washington walking out of his stroller as he tries to get his hands on toys at a local toy store in Gulfport, Mississippi. Washington's parents laugh as they try to get him to step away from his prized possessions.

Josiah Washington was born with a rare genetic disorder, and doctors are still testing to confirm his diagnosis.

"Originally, doctors were going with pyruvate kinase deficiency," Kristian Washington told.

It's an inherited disorder that affects red blood cells and causes shortness of breath and extreme fatigue, according to the U.S. National Library of Medicine.

"He's what I call my miracle baby," the mother of two gushed. "He's reaching all his milestones. He's doing all of it. It's so shocking to us. That's why we record everything he does and take pictures."

Kristian Washington said no one believes her or her husband, Joshua, when they tell them about Josiah's diagnosis.

"He's the sweetest baby," she said. "He's always laughing. We never know when he's in pain. He's just so happy. That's why I can go on ... and be OK with waiting for test results. He just keeps going."
