The "Jackie" actress was pictured stepping out with her baby girl, Amalia, in Los Angeles' Los Feliz area, reported Ace Showbiz.
In some pictures, Natalie was seen keeping her new bundle of joy close to her chest with a black material carrier as she took her to popular walker spot Griffith Park.
The 35-year-old Israeli-born actress left the stroller at home and carried the baby girl in the sling due to the park's walking trails having a steep gradient.
Natalie gave birth to Amalia on February 22, just days before the Academy Awards.
Their first child, a son named Aleph, was born in June 2011.
A year later, Natalie and Benjamin tied the knot in an intimate Jewish ceremony in Big Sur, California.
