Before his wife, Jenna Dewan-Tatum, gave birth to their first child on Thursday, Channing Tatum sat down for an interview with Vanity Fair, where he dished about becoming a parent for the first time.

He correctly guessed the sex of the baby, as he dished to the magazine, "My wife thinks boy. I think girl."

The 21 Jump Street actor, 33, was also honest about his lack of experience in the baby department. "I don't think you can prepare," he said. "It's a bit of a freestyle."

Tatum admits that his parents weren’t perfect when they raised him, but he will try and learn from them. "That whole 'I don't want you to make the same mistakes' mentality," he explained, "my dad didn't have much money growing up; he didn't have much of an education. He forced that on me, and I didn't want it,” Us Weekly reports.

He explained that he was medicated for a learning disability, another thing he will not do for his own child if they have one as well.

"I [still] read so slow. If I have a script I'm going to read it five times slower than any other actor, but I'll be able to tell you everything in it. It kills me that there are standardized tests geared towards just one kind of child,” he said.

He continued, “I truly believe some people need medication. I did not. I did better at school when I was on it, but it made me a zombie. You become obsessive.”

Vowing he will “never do that” to his own child, he also likened it to cocaine and crystal meth. “The more you do, the less it works. For a time, it would work well. Then it worked less and my pain was more. I would go through wild bouts of depression, horrible comedowns,” he said.
