Majandra Delfino on Raising Her Children in a Gender-Neutral Environment: We Want Them to 'Be Well-Rounded'

If there’s one thing Majandra Delfino is nailing as a mom, it’s setting her kids up to grow into who they are without limiting them to gender-traditional ideals.

“We didn’t really allow a lot of princess-y stuff into the house. Not a lot of pink and all that,” the Roswell alum, who is mom to 4-year-old daughter Cecilia Delphine with husband David Walton, shared with PEOPLE Thursday at 4Moms’ Los Angeles launch of their world’s first self-installing car seat.

“I felt like the world was going to do that so much to her [anyway, so] I was like, ‘Let’s try to save this house from too much of it, ’cause she will find it herself,’ ” Delfino, 35 — who also shares 2½-year-old son Louis Augustus with the About a Boy star, 37 — adds of their daughter.

“I’m realizing that she knows what that is because she legit wants to dress like a boy,” Delfino says. “I always try to buy her clothes that I could give to her brother after, so it’s always gender neutral, and she is offended when I give her a skirt now. I thought that was interesting.”

The hilarious mom of two shares that even though Cecilia has migrated toward tomboyish clothing, she has lately been gravitating toward the more traditionally feminine on her own.

“The milestone that she is hitting that is very on-the-nose girl is that she will see something pink or purple and be like, ‘Yes.’ And you’re like, ‘Whoa,’ ” the actress says. “We’ve done nothing to condition it, and it’s just there. The world did it.”

As it turns out, Delfino is seeing the same trend with Louis.

“He’s all about destruction and trucks, and it’s like, ‘What?’ ” she says, explaining, “We tried to do the opposite — we put him in ballet right away. We wanted them to be well rounded.”

Giving an example of just how well-rounded her son already is at such a young age, Delfino adds, “He’s like, ‘Aaaahhh!’ — starts to break things, then he all of a sudden stops and starts [pirouetting].”

Are more children in the future for the Friends with Better Lives actress and fellow actor Walton?

“I don’t know. We had our two children so back to back that there is definitely a part of me that is like, ‘Let’s have two more,’ ” Delfino replies. “And then of course my husband is one of seven children, so he is like, ‘Let’s have eight!’

“And I’m like, ‘With me?’ ” she jokes. ” ”Cause I don’t know, we might have to bring in a ringer.’ ”
