Los Angeles - Brad Pitt's daughter "doesn't listen" to him.
The Moneyball actor's partner Angelina Jolie finds it "very funny" watching him teach five-year-old Shiloh how to ride a quad bike because she is more interested in speed than careful handling of the four-wheeled vehicle.
She said: "It's very funny to watch Brad try to teach Shiloh because she doesn't want to listen. She doesn't want Dad to sit on the back. She doesn't want to learn about the brakes. She just wants to go! It's the combination of the two of us."
Angelina also compared their eight-year-old son Pax to a "punk rocker" because he has a "good heart" beneath his "wild" exterior.
She told the new issue of America's Marie Claire magazine: "He is extremely wild, but he has a very, very good heart. You know, like those punk rockers - when you really get to know them and they are just pussycats. But at the same time, he is going to get in some kind of trouble."
The In The Land Of Blood and Honey star revealed her eldest child, 10-year-old Maddox, looks after her and can always tell when there is something wrong.
She said: "I'll be doing something and I'll be frustrated, and he'll hold my hand and say, 'Are you feeling tired? Is that why you're upset?' "
Meanwhile, she says the couple's six-year-old daughter Zahara has found "her thing" in horse riding, while three-year-old twins Knox and Vivienne have very different personalities.
She explained: "Knox is very much a dude. Very physical, tough. He loves dinosaurs and swords.
"[Vivienne] is so elegant and delicate. Vivi will pick flowers from the garden and put them in her hair. She likes to get her nails done and collects stuffed animals. It's funny for me to have to buy all things pink and watch princess movies!"
Angelina has previously admitted the children have asked when she and Brad will get married, and says they get "giggly and happy" when they see their parents being affectionate because it makes them feel secure.
She said: "If they see Mommy and Daddy in need of some private time because they're going to kiss and whatever, the kids get all giggly and happy. Because it gives them some security."
