Drew Barrymore wants a busy household!

Almost 11 months after she gave birth to her daughter Olive, the actress, 38, told InStyle that she wants more children with her husband, art consultant Will Kopelman.

"I was an only child, and it was lonely," she told the magazine, which hits newsstands Aug. 16. "Some people love it and thrive on the independence, but I want my kids to have other kids around. Maybe two kids so they can run around life together, roll their eyes at their parents together like Rusty and Audrey Griswold from "[National Lampoon's] Vacation." So however that's going to come about, it's gonna happen!"

Why Drew Barrymore Picked the Name "Olive"

The concept of family is important to Barrymore, whose own childhood was chaotic. Now, the actress has credited Kopelman and his "traditional family" for providing a grounding influence in her life.

"Will and I are a nice balance of opposition and similarities. He always says, 'Being calm is so important' because I tend to be not calm," she said. "I probably act more like a chicken with its head cut off! But I can also be very strong. I'm entering my 40s, and now I get to step back and take these incredible, extraordinary life experiences and life lessons and apply them to being a parent."

For Barrymore, that means making sure that her daughter is raised in an environment that's "safe, nurturing and loving - and silly and free, also consistent and grounding," she said.

"I love the person who said, 'Parenting is like wearing your heart on the outside of your body.' It's the most beautiful, perfect analogy. I have anxieties about how much I'd like to get it right," she added. "Then I just have the same typical fear every other parent has: Are they going to fall down?"
