Kol's story . . .

. . . is up on the Brain Tumour Foundation website.  Check it out!  Here's part of it.

In April 2010 Kol was suffering from regular headaches and nausea. Initially Kirk and Kristen thought it could have been food sensitivities, so they began changing diet and looking for patterns. Concerned about the headaches, Kristen took Kol to the doctor but because Kol also had ear and throat infections, that was determined to be the issue. Then on May 25, 2010 the headaches became much worse and just wouldn’t go away. . .
