“One year ago tonight, I sat alone in a hospital room with my newborn son pondering our future,” Cohen recalled. “I didn’t know then how his smile would brighten my day, what simple joy each new progression of his growth would bring, and most of all what a lovely boy he would become.”

“I am so grateful to my surrogate in California who made this all possible, and for every day of our first year… and can’t wait for the next,” Cohen added. “Happy Birthday sweet little Ben. #dada.”

“I was in the delivery room. I had been hoping that he would have a full head of hair, and he really overdelivered,” Cohen joked at the time. “That was the first thing you see, the head of hair coming out. And I was amazed.”

Almost 10 months later, Cohen opened up to PEOPLE about how much he has been enjoying fatherhood, despite the ups and downs.

“It can feel overwhelming, but when he looks back at me and smiles or laughs at something I say, everything feels right,” he said.

“I had a join first birthday slash Super Bowl party for Ben,” Cohen said. “It was nice, it was a great party. I had family, I had friends. It was lovely.”

“The headline of my thing was that my son — who was downstairs from 4:30pm until 7:30, being passed around from person to person — didn’t flinch,” he added.
