Her leading men! Olivia Wilde keeps it casual for outing with Jason Sudeikis and son Otis... as newborn daughter Daisy stays home

She just gave birth three weeks ago.

And while Olivia Wilde has been busy doting on newborn daughter Daisy, she spent some time with the men in her life on Saturday.

The 32-year-old couldn't stop smiling as she stepped out with fiance Jason Sudeikis and their two-year-old son Otis in New York City. 

Three of a kind: Perhaps Olivia Wilde and fiance Jason Sudeikis simply needed a break from caring for an infant when they stepped out with only two-year-old son Otis on Saturday

The House star opted for a very casual outfit consisting of a black T-shirt layered under a fleece-trimmed jacket, and some loose-fitting black jeans which she cuffed at the ankle.

A pair of black slip-on sneakers were no doubt a comfortable choice for the walk.

She hid her brunette locks under a knit beanie, and shielded her eyes with a pair of large cat eye-style sunglasses.

Fiance Jason, 41, also looked quite laid-back in a lightweight black coat, ribbed sweater and jeans.

It seemed as though he coordinated some aspects of his outfit though, as his light blue baseball cap appeared to match his light blue and white Nike sneakers.

The SNL star also sported a pair of amber-lensed aviator sunglasses and a vintage-style camera around his neck. 

Son Otis looked like he took his low-key style cues from his parents, as he rocked a pale blue sweatshirt, khaki pants and some red slip-on sneakers.

He also wore a green and yellow striped beanie to keep warm.

It appeared that the family had quite a bit of fun while they were out, with Otis even apparently getting in a little hide-and-seek with mom Olivia. 

At one point Otis looked to have found a prime hiding spot underneath a sandwich board sign, though mom quickly located him.

Olivia announced Daisy's birth on October 11 with a sweet Instagram photo of the baby, along with the caption: 'There goes the neighborhood. Daisy Josephine Sudeikis. Born, like a boss, on #internationaldayofthegirl.' 

Found ya! At one point Otis looked to have found a prime hiding spot underneath a sandwich board sign, though mom quickly located him
