It's a monumental accomplishment for a little boy that was born with the cards stacked against him.
"I'm a new mom and I already have to sign DNR papers for my little guy?" explained Alysa York.
Doctors knew something was wrong with Braxton when he was born on Christmas Eve 2016, but they weren't sure what it was.
A month later he was misdiagnosed; doctors told York the baby may not even make it past his first birthday.
But a month later, a new doctor brought hope - Braxton was diagnosed with a condition known as "hydrocephalus," where fluid builds up within the brain.
Doctors were optimistic Braxton would live but weren't sure what his quality of life would be like since his case of hydrocephalus is considered severe.
But in the video Alysa took of Braxton with his physical therapist, you see him take his first steps with the help of a walker. By Friday night, the video had over 5.3 million views and 66,000 retweets.
"And if he wants to walk, go ahead and run for the stars, little boy. I'm here," said York.
The York family is now trying to raise money to purchase a wheelchair-accessible van for Braxton. If you'd like to help, click here.
