She wrote: “As this baby grows inside and I attempt to breathe through the fears and unknowns of this time, I am thinking of all you other mamas bringing new life into this world right now.
“And also of all the women across generations and centuries and borders who have and are currently birthing new life in the midst of so many extraordinary and daunting circumstances.
“Life is a miracle, and mamas make it possible through their strength and power. Hang in there pregnant mamas! We got this.”
