Hendrix called it a "cruel and unusual punishment" for recently separated parents.
She added, "This is not healthy. This system, when you break up with someone, you're meant to go your separate ways. You're meant to be out of each other's lives. It's really a cruel system to have to see that person so regularly. It's not right, but it has to happen."
Hendrix explained that she has "90 percent" care of Harper-Rose.
"[Garner] has her one night a week and then usually for a couple of hours another day in the afternoon," she said.
Hendrix also explained that she and Garner have one rule when it comes to co-parenting.
"No changes can be made to the parenting plan without at least two weeks notice," she explained. "So you can't just be like 'Oh, I can't have her on this day [without much notice].'"
Hendrix and Garner met on Season 1 of MAFS in 2015, and continued their relationship outside of the eight-week experiment. They welcomed Harper-Rose in November 2016.
