"My dream is to be a highly fulfilled and productive stay-at-home mom and wife," Roberts says in an interview with Vanity Fair magazine. "The highest high would be growing our food that I then make, and then composting and growing more - that kind of circle."
Roberts, 40, and Moder, 38, are the parents of 5-month-old Henry and twins Hazel and Phinnaeus, who turn 3 this month.
Roberts said that three children are enough for her and she has no plan to expand the household because she worries about the environment. "You can't help but be aware, because now we are a home of five people."
"[At] this point I'm having so much fun with them. You only have so much energy, and you want to put so much energy into each child," Roberts said. "And they're a really good trio, these three."
Meanwhile, after five years of marriage, the Oscar winner says that her relationship with Moder is going strong, and that tying the knot back in 2002 was the "most correct decision I've ever made in my life."
"My whole body knew: Yes. He's just my favorite guy," she says.
