He spots his son Michael across the room and is overjoyed to see him walk over to him for a hug. Six-year-old Michael has cerebral palsy, and when his dad left for Afghanistan he couldn't walk. In fact, doctors told his parents that he may never learn.
The video was posted on the blog by Michael's proud mum Melissa with the message:
"When my husband left on his deployment, our 6-year-old son could not walk on his own. He has cerebral palsy. Doctors originally said that he would never walk or do much of anything.
"While daddy was away, he learned to walk. For his homecoming, we set it up for Michael to walk to his daddy for the first time ever! We kept the fact that he could walk a secret the whole time his dad was gone!"
