The 30-year-old actress is the first to admit, though, that feeding time with son Otis isn't always quite that picture perfect! "Usually he has a diaper on," she told Today's Savannah Guthrie Monday, "and I've never looked that good breastfeeding, and I never will."
Posing for the sweet mother-son picture "grew out of a very organic moment," Jason Sudeikis' fiancée explained. "I was working—I was shooting the cover of Glamour, and I needed to fed my son Otis. So he came to work and I had to feed him. Either I was going to do it off camera or on, and I thought, you know what? Shoot it, because this is part of my real life."
Olivia also talked with Savannah, who is expecting her first child, about how she and Jason chose son Otis' "soulful" name. "We had battles over other names," she said, but "not with Otis!"
"I wanted to name him after Otis Redding," she explained, "and I thought, if you like this one, we're gonna go with this one!"
Olivia also gave some parenting advice to Savannah for when she welcomes her little boy or girl. "I think patience—patience with yourself, patience with the baby, and understanding that you're both learning and you'll figure it out," she said. "But it's just so much fun. Every day's an adventure."
