Perhaps he should cut himself a little slack, as he already admitted being eager to help out with the diapers.
"I've never been so excited when something poos," Tatum said on "Good Morning America" earlier this week. "I just get so amped up because I'm in the game now ... I've gotten so good at changing diapers, swaddling and get it back before she cries."
He was also stoked about his first Father's Day, which told Handler he enjoyed with both his father and father-in-law this year.
Super-dad aside, the "White House Down" star had props for all women after his experience in the delivery room.
"There's a real reason why God did not give us [men] this ability to have babies because we would not be able to do it," he said to the "Chelsea Lately" host. "You guys, I don't know how you do it.... It's a real thing. It's like National Geographic. Like, animal style, for real."
Fans can see Tatum doing what he can do in "White House Down," costarring Jamie Foxx, now in theaters.
