Olivia Wilde and Jason Sudeikis haven't set a wedding date yet.
The 'Drinking Buddies' actress, who got engaged to the 'We're the Millers' star in January 2013 and welcomed their first son, Otis, into the world last April, insists she doesn't feel under pressure to walk down the aisle, as they're already "fully committed" to each other.
The 30-year-old star told the September issue of Glamour magazine: "We're engaged, but no specific plans yet. We just have to find the time to put it together."
She added: "In many ways, a child is more of a commitment. We are fully committed and really happy as a family. And there's no definition of the 'normal family' anymore. Kids today are growing up with so many different definitions of family. I guess what I'm saying is that I don't feel any pressure to do it. But I think it will be really fun."
The couple were both previously married to other people, and Olivia insists she learned a lot from Italian prince Tao Ruspoli, whom she split from in 2011 after eight years.
She said: "[I] wouldn't be this person without that first marriage. I really grew up with my first husband. Now I'm in a much wiser, more centred place in life. I think if we can see people in our lives as chapters, we have a much healthier perspective about the whole thing. It's like it had to happen the way it happened. Jason and I lived two blocks away from each other for years and never met."
The brunette beauty, who was photographed breastfeeding her son for the magazine, admits she feels she should always be feeding him.
She said: "Being shot with Otis is so perfect because any portrait of me right now isn't complete without my identity as a mother being a part of that. Breastfeeding is the most natural thing."
The 'Longest Week' star added: "I don't know, now it feels like Otis should always be on my breast."
