In February 2019, Richards opened up to PEOPLE about raising her daughters — "I'm most proud of raising my kids, especially in a time that is very different from how I was raised," she said — as well as the unique set of challenges she has with Eloise.

Richards recounted when she first noticed that Eloise wasn't reaching typical milestones for babies.

"She wasn't able to sit up on her own for a very long time, and she didn't start walking until she was 2, and that was with physical therapy," she said. "She can only say a handful of words."

However, Richards has remained optimistic. "Every child is different," she told PEOPLE at the time. "You take care of your children no matter what is going on with them."

"I don't know if [Eloise] is ever going to talk like a typical child. But as a parent, you want what's best for your children, and you just do it," the Wild Things actress added.
