"This kid has come to me with his own life, and mine is not his and his is not mine," Perry tells PEOPLE.

Tyler Perry has played his fair share of challenging roles — including a female — but his latest project could be his hardest yet.

The actor and director, 45, welcomed son Aman Tyler, with girlfriend Gelila Bekele in November, and the first-time father is still settling into life with his baby boy.

“It’s been two weeks today. It’s been surreal, incredible, moving,” Perry told PEOPLE at the N.Y.C. premiere of Selma, produced by his good friend and colleague, Oprah Winfrey, on Sunday.

He adds, “I see my face in him every day and it’s pretty wonderful.”

And while he’s still learning the ropes of parenthood, there’s one thing Perry is already confident he won’t do: use his award-winning directorial skills on his son.

“[I’m surprised] how much of a personality he has of his own,” he says. “Just watching his facial expressions and realizing that this kid has come to me with his own life, and mine is not his and his is not mine. I’m just here to usher him.”

He’s also here to change diapers — though Perry admits he has a disadvantage when it comes to his daddy duties.

“It’s hard and difficult for me because I have very big hands, so I’m not that comfortable at it yet,” Perry tells the New York Post‘s Page Six. “He’s very small. I need him to get a little bit bigger, then I’ll be better.”

One milestone the father-son pair have managed to already meet together? “I’ve been christened,” Perry jokes. “He’s peed on me, but it’s all good.”
