On Monday, Feb. 3, the Yellowjackets actress, 29, did a Q&A on her Instagram Stories and was asked by a fan how her baby son, whom she shared in September would be born with a cleft lip, was doing after recently having surgery.

"So so so well!! He's incredible," Hanratty shared. "The surgeon did such an amazing job! It was a 3 hour surgery and it was absolutely terrifying but our little one is so strong!"

"He has nose stents in and will for a little bit longer," she added.

In the fall, Hanratty posted a video on her TikTok and shared that her baby boy would be born with a cleft lip.

"I've been doing some updates on here and having a good time sharing these things with you and I thought I would share our latest update that our baby is going to have a cleft lip and a possible cleft palate," Hanratty said.

"And at first the news was obviously shocking because it doesn't run in my family, it doesn't run in my husband's family," she continued. "And the biggest thing that we all want is that we want our kids to be happy and we want our kids to be healthy."

Hanratty went on to say that finding out her son will be going through several surgeries so soon after he is born was tough, but she's thankful to have found wonderful specialists to work with.

"It's still scary to think that your precious little baby is going to be going under anesthesia and that there's going to be difficulties," she explained.

In December, Hanratty welcomed her first baby, sharing the news on her Instagram on New Year's Eve.

Alongside a black-and-white photo showing the actress' infant's hand wrapped around her finger, she wrote, "And just like that...my world got brighter☀️12-31-24."
