Proving once again that doctors are not always right.

The Canadian Press: Through tragedy, crew member works to put Earnhardt in victory lane

Doctors diagnosed Cayden with holoprosencephaly, a disorder that prevents complete development of the brain, in the womb and told Arnold and his wife, Shira, that he would likely die before being born.
Cayden proved them wrong – and then some.
"We prayed to have 10 minutes with Cayden so we could hold him and love him," Arnold said. "And God gave us 4 1/2 years."
Still, the Arnolds were told to lower their expectations. Cayden was born blind and deaf, and wasn’t likely to develop mentally.
"We were told that he would not know love, he would not know who his parents were – basically, that he would most likely be a vegetable," Arnold said. "And he certainly proved that theory to be wrong."
With an implant, he could hear. His vision developed. He could recognize colours and objects.
And he certainly knew who his parents were.
"You just knew by his gaze at you, his smile," Arnold said. "He would move his arms the best that he could with a sense of excitement when he saw you come into a room or spoke to him or touched him. He certainly was aware of people around him, and absolutely knew his family."
