Claire Danes is opening up about the challenges of motherhood.
In the latest issue of Harper's Bazaar U.K., the 35-year-old actress, who gave birth to son Cyrus in December 2012, says parenting isn't always easy.
"Being a mum is incredibly challenging, but we still feel a pressure to talk about it in very romantic terms. And it's not just that," Danes tells the mag (October issue on sale Sept. 3). "We all have that resentment at times and anxiety about being trapped by the role, that responsibility. And then chemically it can run riot...And there's no ‘off' button. [For me] that was the hardest adjustment. You always feel beholden to somebody...And for so long they're like koala bears, you just feel a physical responsibility to be there for them to cling to. It's pretty primal."
