"I was in the delivery room. I had been hoping that he would have a full head of hair, and he really overdelivered," he joked at the time. "That was the first thing you see, the head of hair coming out. And I was amazed." After Cohen "cut the umbilical cord" himself, doctors cleaned Ben off and brought him over to the new dad, who then went skin-to-skin with his newborn for the first time. "He was so alert for the first two hours. His eyes were wide open. He didn't cry; he was just calm," Cohen recalled to PEOPLE. "I kind of have no words for it."
