T.I. is talking for the first time about the birth of his son Major Harris.

In an MTV News exclusive, T.I. talks about assisting in the delivery room.

"[Reports] said he was 5 pounds and 15 ounces," Tip said of his newborn. "That was wrong. He was actually 7 pounds and 4 ounces. I was in the O.R. Hands-on. I was trying to help. ... Tiny's all right. She's a soldier."

Major Harris was welcomed into the world by T.I. and longtime companion and former member of Xscape Tameka "Tiny" Cottle. The pair suffered a tragic miscarriage last year and this was a concern going into Major's birth.

"It was a major concern, but I had to walk in faith," T.I. said. "Before it happens to you as a parent, it's never anything that you'd even consider..."

T.I. also discussed handling babysitting duties while on house arrest on federal weapons charges.

"I was the babysitter...You always know it's somebody there now. The kids know they couldn't get away with nothing. I spent more time with them than I did since before anyone knew who T.I. was. I appreciate it. I value that time I got to spend with them."

T.I. will release his new album "Paper Trail" in August.
