Thirty-year-old actress Olivia Wilde posed for a fashion shoot where she is seen breastfeeding her new son, Otis who is now five months old, for the September issue of Glamour magazine.

She called the shoot with her son "so perfect," saying that her identity is not complete without her part as a mother being shown. She also said "breastfeeding is the most natural thing." Obviously, Wilde is proud to show how she has fully embraced the joys of motherhood.

The photo shows the actress in a diner booth nursing her son. She later on revealed in an interview that it was necessary to be photographed that way to show that being a mother is not part of her full identity.

Other photos in the set include Wilde cradling her son in her arms, taken in the same diner where Otis sits on the counter as well. In the photo, she appears to be entertaining her son who, is wearing a diaper as opposed to the previous photo where he did not wear anything.

Aside from the official set of photos taken by Glamour magazine, Olivia had also shared photos of herself and her son on Instagram, where Otis is shown peeking over her shoulder -- the two in a more casual setting, HollywoodLife reports.

Otis wore a grey baby hoodie while his mother wore a loose shirt with the words "Rock and Roll" and her hair let down. It was posted in mid-July when Otis was about 2 months old with the caption "Rock and roll, baby."

Otis was born on April 23 to first-time mother Olivia and her fiancé Jason Sudeikis. Since then, the couple has not been spotted around so much and Otis was kept covered and hidden from the public's view until now.
