The new mom thanked fans for all of the messages she received after she and her hubby Ryan Reynolds welcomed their first child together, posting a sweet note on Instagram Tuesday.
"Thank you everyone for the well wishes in this special time!," Blake captioned a shot, which showed her in the middle of a group of women, rocking a side ponytail, a dog sweater and a plaid top underneath it. "Send some love to our girls in Boston tonight at My Life My Choice. They are the face of empowerment. Watch, A Path Appears, tonight on PBS at 10pm EST, please. I promise the stories from these girls will change your lives like they did mine. #girlpower #apathappears #halfthesky #changeisnow."
The post marked the Age of Adaline star's first Instagram since becoming a mom. While juggling motherhood and her career, Blake took time to get involved with the cause, which is close to her heart.
She appears in the documentary A Path Appears, which shows Blake and other stars traveling around the world exploring the effects of gender inequality and poverty and trying to find ways to improve it.
"I have a new perspective of what it means to have your body sold in this country," Blake said in a clip from the film, referencing her involvement with My Life My Choice, which has a mission to end the sexual exploitation of children. "Not everybody is free. I see how much more opportunity people need."
A Path Appears airs Jan. 26, Feb. 2 and Feb. 9 at 10 p.m. on PBS and features Blake, Eva Longoria, Jennifer Garner and more stars discussing sex trafficking in America and beyond.
