Angelina Jolie and Brad Pitt have six beautiful children, but originally they wanted many, many more.

The golden couple of Hollywood apparently found six to be the perfect number–or at least, the number they can handle without exhausting themselves–and Pitt says he’s the disciplinarian in the house. That is, with the boys. The girls, he says, get a pass.

“Everyone talks about the joy of having kids—blah, blah, blah. But I never knew how much I could love something until I looked in the faces of my children…Girls do no wrong. I feel like my job is to show ’em around, help them find what they want to do with their life, put as many things in front of them, and pull them back when they get out of line, so they know who they are,” Pitt says.

Although he says the house is “chaos” when everyone is home at the same time, he also admits it’s fun being a parent even if it’s more of a challenge because of the work schedule he and Angelina have to work out. Because they travel so much, they have to put a lot of effort into the kids’ daily lives to make everything work.

“Because we’re migratory workers in a sense, they have this wonderful thing where they get to be students of the world. They have memories of being in Vietnam, or that time in Paris, or over in Calgary. The downside is friends, sleepovers, team sports—these have been the challenges that we’ve had to work out. We do those things, but we really have to go out of our way. And Mom is a matador about it all—she’s fantastic. We get their friends to us a lot,” Pitt told the Telegraph.

Outside of their careers, Brad and Angelina are well-known for their philanthropy, particularly Angelina, who is an ambassador for the UN. Earlier this year, she went public with her decision to have a double mastectomy after doctors discovered she carries the BRCA1 gene, which raises the chances of breast cancer greatly. Because she had so many family members die of cancer, Jolie decided to take preventative measures. After she shared her story, Jolie garnered headlines because of all the awareness she’d raised–and potential lives she’d saved.
