Wilde, who is engaged to Otis’ dad Jason Sudeikis, told the mag, "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."
She added, "I don't know. Now it feels like Otis should always be on my breast. It felt like we were capturing that multifaceted woman we've been discussing — that we know we can be. You can be someone who is at once maternal and professional and sexy and self-possessed."
Wilde also tweeted the pic, along with the message, "Otis ordered milkshakes. Luckily I had some on me. Then he peed on my dress. Good kid. #boobfood #whennaturecalls."
In the article, Olivia discussed her relationship with Jason, "We're engaged, but no specific plans yet — we just have to find the time to put it together. In many ways, a child is more of a commitment. We are fully committed and really happy as a family."
In her opinion, “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."
