Olivia Wilde welcomed her daughter to the world on International Day of the Girl, and now the actress is celebrating "the power of a woman" in a new photo with little Daisy.

In the sweet pic she shared on Instagram, Wilde smiles for the camera while breastfeeding the 2-week-old.

"My drinking buddy," she wrote (likely a wink at her 2013 movie "Drinking Buddies").

Wilde's shirt summed it up perfectly: "Never underestimate the power of a woman."

If Daisy's look of contentment is any indication, she fully appreciates the power of mom.

Wilde and partner Jason Sudeikis are also parents to 2-year-old son Otis, and when their boy was just a baby, she spoke out about the importance of breastfeeding.

"Breastfeeding is the most natural thing," she said in a 2014 interview with Glamour magazine. "I don’t know, now it feels like Otis should always be on my breast."
