It’s a baby girl for Mackenzie Douthit McKee!

In Touch can exclusively reveal details about the birth. The Teen Mom 3 star, 19, and her husband, Josh McKee, 20, welcomed a daughter around 12:43 p.m. on Friday, Feb. 7, in Miami, Okla.

“I am so thankful for a healthy baby girl,” Mackenzie tells In Touch.

They named her Jaxie Taylor – a homage to her grandfather Jack. Taylor is Mackenzie’s middle name as well.

“Many friends and family were praying and everything went great!” she adds. “She is a beautiful miracle from God. I feel very blessed.”

The little one came in at 8 lbs., 9 oz. and 19 inches long via C-section.

“My blood sugars and the baby’s were fine during the delivery,” says the reality star, who’s already mom to 2-year-old son Gannon.

Doctors warned Mackenzie against having a second child, since she’s a type 1 diabetic, which means she could slip into a coma during labor.

But the teen was intent on having another baby.

In fact, Mackenzie says she credits Jaxie’s birth for saving her relationship.

“Jaxie saved my marriage with Josh and kept our love alive,” she tells In Touch. The two were married in August 2013.

“God’s timing is not always our timing, but He always knows best.”
