Teen Mom 3 star, Mackenzie McKee, welcomed a baby boy yesterday, but it sounds like the reality star endured considerable stress in the run-up to her child's birth this week.

Taking to social media to ask the public for their prayers and support as her daughter prepared for labour, Mackenzie's mother, Angie Douthit, appeared particularly anxious.

Sharing a photo of her 21-year-old daughter and her husband on Facebook, Angie wrote: "Prayer alert: Mackenzie is having a c section n a few minutes." (sic)

"She is type 1 diabetic and the babies heart rate is high. He will be in the NICU for a while even though he weighs over 9 pounds, (according to ultrasound).," she continued.

Explaining that her daughter would welcome support, Angie added: "Mic is very nervous and scared. Please pray."

Thankfully, just an hour later Angie shared the news the family were hoping for, writing: "He's here!!! 10 pounds 1 ounce. I haven't seen him yet, but they r ok for now! Praise God!" (sic)

"Baby is in NICU with a navel IV and a tube for breathing," Angie told followers concerned for Mackenzie and her child's condition. "He'll be there for a few days. Please keep praying."

Social media users have responded in their droves and wasted no time wishing the family the best as they navigate the next few days.

Mackenzie, who is also mum to four-year-old Gannon and two-year-old Jaxie, has named her newborn son Broncs, and we are wishing her all the very best.
