She told British Vogue: “We had already decided on a home birth, because of concerns about negative birth outcomes for black women in America – according to the Centres for Disease Control and Prevention, the risk of pregnancy-related deaths is more than three times greater for black women than for white women, pointing, it seems to me, to systemic racism.
“We never imagined that in the coming weeks, hospitals around the country would begin restricting who could be present in the birthing rooms, forcing mothers to deliver without the support person or people of their choice.
“Delivering at home ensured that I had what every single woman deserves to have: full agency in determining my birth support.”
