Oklahoma toddler learns to walk on prosthetic leg

Lincoln Mouser, an adorable 1-year-old boy from Tulsa, Oklahoma, is still a little unsteady on his feet.

Born at just 23 weeks, premature Lincoln suffered circulation problems as a newborn and subsequently lost his right leg to amputation at just four weeks old. His twin sister, Abigail, died just days after birth.

The determined tot now walks on a cutting-edge prothesis — Lincoln was originally fitted with it when he was just crawling — that adjusts to accommodate his growing body.

"He is probably the most determined little baby I have ever met in my entire life," Lincoln's mother, Andrea Mouser, told Fox23.

"He isn't tentative, it's his leg and he doesn't know any different," Scott Stromberg, a certified prosthetist at the Hangar Clinic where Lincoln visits monthly, told FOX23.

"He is a breath of fresh air and our little inspiration," said Robert Mouser, Lincoln's father.

"It makes us feel amazing and wonderful and very proud because initially, we didn't know if he'd ever be able to walk. Seeing him progress from crawling now to walking is a great feeling," added Andrea.

As with any adventurous youngster, "it's going to be hard to keep him out of stuff," the proud mother told KTUL.
