“I know the yearning. That yearning. It’s a huge, aching yearning. And the loss! The loss of a miscarriage is not talked about enough,” the 50-year-old actress said. “That’s massive grief to certain women.”

Kidman suffered a miscarriage in 1990 when she was 23.

The miscarriage led Kidman and Cruise to adopt their children Isabella and Connor in the years after.

“There’s an enormous amount of pain and an enormous amount of joy on the other side of it,” Kidman said of becoming a parent.

“The flipside of going through so much yearning and pain to get there is the feeling of ‘Ahhhh!’ when you have the child.”
