Fahd Abu Haikal was driving through Hebron last week when he spotted a group of Israeli soldiers.
He began to slow down, but one of the soldiers raised his rifle & opened fire.
One bullet pierced the windshield, striking his son, Sam, in the head.
He was just 7 months old -- the 13th child to be killed by Israeli security forces in the West Bank so far this year.
The IDF says it is investigating the shooting.
