The actress told People that she started teaching her 13-year-old twins, Slater and Bronwyn Vance, about respect at an early age.
"Since they were very, very little you just give them enough information ... then they adopt it and take it," she told the outlet.
"I used to say to my son when he's wrestling with his sister -- wrestling back and forth and trying to take her down -- and she'd say, 'Stop!' and I'll say, 'When a girl tells you stop, stop. When a girl tells you no, she means no.'"
She shared that the idea seemed to click for her son during a trip to Mexico when he was 4 years old.
The actress recalled, "I'm being harangued to buy a sarong, buy some jewelry ... a churro ... And I [said] no, no thank you, and he looks at the man and says, 'When a girl tells you no, she means no."
Respect and consent are important teaching points for the actress, as she has dealt with trauma in the past. She previously opened up on being sexually assaulted by her mother's boyfriend at the time when she was younger.
"Fortunately, it wasn't a complete assault, it was fondling, but it was devastating enough for a child who's 12 or 13," she said at an event for the Rape Foundation in October, according to Variety.
"Thankfully, to have a mother who could tell as soon as light broke that this happened and for her to expel him," she continued. "That she heard me, believed me and did something about it, I think was so empowering for me as a young teen, as a young woman."
As a parent herself, she has emphasized the importance of consent from an early age.
"I started that early because of experiences with friends, and I know that they will be in situations one day," she said. "When a girl says no, both to him and to her, she means no. Back up. She has to say, 'come here, kiss me'."
