For 18-month-old Jordan Berge, walking is a medical feat.

The Omaha, Nebraska, boy was born with skeletal dysplasia, a rare disease that only 17 people in the world have. The disease causes bones to grow smaller than they should.

 As a result, Jordan spent two weeks at the NICU when he was born and spent the following year in and out of the hospital. He also breathed with an oxygen tank.

"The bones were not measuring what they should be. So the concern was then at birth was, 'Would he be able to breathe on his own?' Because if the rib cage was too tiny for the lungs to be able to breathe for him then he would not be able to,"  his mother, Lisa Berge, told WOWT 6.

It was music that got Jordan on his feet.

"He loves music and he just reacts to it. His dancing was always little movements until we got him standing up and then his booty started shaking," Lisa Berge said.

Water therapy helped strengthen Jordan: "That has made huge differences in his milestones because the water helps him to stand better, helps him to be able to be on his hands and knees better."

It is in part because of the therapy that Jordan was able to take his first steps last week.

"The whole house celebrates. We scream. We cheer him on -- it's pretty loud in here. We're so unbelievably proud of him and want him to do anything and everything that's possible in his life and we will help do that."
