For the picture, the Legally Blonde star went makeup-free and wore a black top, while Ava sported a gray sweatshirt and a pair of sunglasses placed atop her head. Deacon, meanwhile, wore a white henley shirt and a tan-colored hat on his head.

There, the mother of three spoke to Kristen Bell and Monica Padman about the obstacles she faced when she and her then-husband welcomed their daughter. Witherspoon gave birth to Ava in September 1999, about two months after she and Phillippe, 46, wed. The pair would then go on to welcome Deacon in October 2003, before separating three years later in 2006. Reese Witherspoon Dances Around Her Kitchen to Celebrate Kids Returning to School "I did not have a lot of support with my first baby and I learned really early, like this is not going to work," she said. "I tried to muscle through for five months with Ava, just not sleeping and I became delirious." Noting that she "couldn't have worked" through the first few months she was a new mom to Ava, Witherspoon explained, "I was lucky enough to have money saved and I didn't have to work, but it's just not a one-person job." "I would even say it's not a two-person job," the Big Little Lies star added.
