"My daughter has been having nightmares," says the O.C. alum. "For me to be able to calm her down has just been a real accomplishment."

"I got my daughter to go on an upside-down roller coaster," she says. "I was so proud of her for being adventurous and then getting off and saying, 'That was terrifying. I'm never doing that again.' But at least she did it."
Christensen and Bilson, who cohosts a new podcast, Broad Ideas, with best friend Olivia Allen, welcomed their only child in October 2014, before calling it quits on their relationship in September 2017.
Last year, the actress spoke to PEOPLE in an exclusive interview about how she and Christensen found the trick to successful co-parenting since their split.
"Communication is key and just being on the same page, so everything's about the kid," she said. "As long as you put the kid first, everything will be okay."
