Duck Dynasty's Sadie Robertson Welcomes Baby No. 2 With Christian Huff

The Robertsons are continuing to share insight into Mia Robertson's health journey.

Duck Dynasty alums Missy Robertson and Jase Robertson sent out a call for prayers from their fans as their 20-year-old prepared to undergo her 16th surgery to repair her cleft palate.

"Just another night in a very familiar hotel room," Missy wrote on Instagram July 28 alongside a photo of herself and Mia. "I don't say 'last' and I don't say 'minor' anymore, but I still ask for prayers. @miarobertson1 undergoes #16 tomorrow."

And of course, the reality star's fans were happy to lend their support, with one commenting, "Praying for Mia bless her heart!!"

Another fan recalled the surgeries her own "cleft cutie" had undergone, adding, "I just said ‘let's not count anymore.'"

As for Mia, she maintained a positive attitude going in surgery, posting a photo with her mom from the hospital to her Instagram Stories with the caption, "sweet sixteenth surgery with my rockstar mom!" She also added a prayer hands emoji, writing, "last one."

Over the years, she's kept fans up to date with her surgeries, expressing after undergoing her 13th surgery in 2021—which at the time she hoped would be the last—how much it meant to have her family by her side.

"surgery isn't the most fun but with such amazing family and friends it's hard not to feel loved:)," she wrote on Instagram. "hard to believe surgeries are over but so thankful for the journey:)) thanks for the prayers!!!"

Mia was born with a bilateral cleft lip and palate, with her family recounting her journey through the Mia Moo Fund, a foundation they started in 2014.

Mia underwent her first surgery at 3 months old, the site notes, and over the years has gone one to have several operations for lip correction, on her nasal passage and a bone graft, among others.

And because of this, Mia and her family—which includes siblings Reed and Cole—have dedicated themselves to the Mia Moo Fund in the hopes that they can help others who find themselves in similar situations.

"The mission of Mia Moo is to inform, inspire, and improve the quality of life for children born with cleft lip/palate," the family shared on the site. "Here at the Mia Moo Fund, our desire is to make sure that each and every child born with a cleft lip or palate receives the best possible medical care, regardless of his or her financial situation."
