Mitchell and Babel welcomed their second child together, a baby girl named Rome, in May 2022. Mitchell confirmed Rome's arrival to People in June, saying, "I feel awesome. I feel really, really good. It definitely takes a village. I'm really lucky my parents are in town and everybody's been really helpful."
She also noted that her daughter Atlas is "loving being a big sister." She added: "She is so excited. She's been incredible. She helps me change diapers and it's good — she loves it."
Mitchell also announced Rome's arrival on Instagram alongside a photo of the two snuggled up together. "Losing the most important person in my life in the same year I welcomed my second daughter has shifted everything for me, but one thing remains steady in my soul," she captioned the post, referencing the recent loss of her grandmother. "I'm certain they spent time together and that brings me peace and joy. We're so happy you're here Rome, named after my best friend, my soulmate, my 'person,' my Grandma Romaine. ❤️."
