“I have spent the last two months in and out of surgeries with my eldest daughter, and days ago watched her younger sister go under the knife for a hip surgery,” the Oscar winner wrote, choosing to withhold their names.

The actress-activist said her daughters “encouraged” her to write the piece, titled “Why Girls Deserve Love and Respect on International Women’s Day,” despite the private nature of it. “They understand that going through medical challenges and fighting to survive and heal is something to be proud of,” she explained.

Jolie noted her sons were “supportive and sweet” while their sisters recovered but wanted to focus on her daughters because of the holiday.
