In February, Cohen opened up about finding a surrogate to bring his dream of being a dad to fruition.

“Iworked with an incredible surrogate,” he told PEOPLE at the time. “She was in California. Surrogacy is illegal in so many states, including New York. I don’t understand why. It’s a voluntary process, obviously.”

“My surrogate just viewed it as, she was giving me the ultimate gift. She gave me life,” Cohen added. “So I’ll be forever indebted to her.”

The surrogate gave birth to Benjamin on Feb. 4 with the Bravo star in the room. “I had been hoping thathe 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.”

“It can feel overwhelming,” Cohen admits of raising Benjamin. “But when helooks back at me and smilesor laughs at something I say, everything feels right.”
