It's almost as if Sharon Henderson had seen it all before -- and felt the pain already.
She had already lost her first son, Jeremiah, in 2003, after a short life riddled with ailments.
Now, Sharon is fighting the same emotional battles again, this time alongside her second son, Dallas.
Dallas lives with two major genetic disorders, which have taken away his ability to walk. Neurofibromatosis type 1, or NF1, has caused bone problems and learning disabilities, as well as the growth of benign tumors along the course of nerves throughout parts of his body. He also has an unknown skeletal dysplasia, which is a type of dwarfism.
In 2010, his airway was damaged during a dental procedure, causing grade 4 stenosis. Because of the stenosis, Dallas received a tracheotomy that must be monitored and kept in place at all times.
These conditions have left Dallas in need of constant care. Now, he either has a night nurse, a day nurse or his mother, Sharon, at his side at all times. But Dallas doesn't see these conditions as a limitation -- and neither does Sharon.
