Sandra Bullock has adopted her second child.

The Oscar-winning actress revealed the news exclusively to PEOPLE for the magazine’s latest cover.

“When I look at Laila, there’s no doubt in my mind that she was supposed to be here,” Bullock, who adopted the 3-year-old out of foster care in Louisiana, told PEOPLE. The actress previously adopted her son Louis, who is now 5, in 2010.

“I can tell you absolutely, the exact right children came to me at the exact right time,” she said.

Bullock has had a busy year, starring in Our Brand Is Crisis and providing her voice to the hit film Minions, appearing on numerous magazine covers, and using her platform to discuss issues such as sexism and racism.

“I feel like it’s become open hunting season in how women are attacked and it’s not because of who we are as people, it’s because of how we look or our age,” Bullock said to E! Online. She added that how the media treats women was difficult to reconcile while raising a son. “I’m trying to raise a good man who values and appreciates women, and here we have this attack on women in the media that I don’t see a stop happening.”

In a later interview, Bullock was asked how she handles discussions of race with Louis. “It’s an open conversation we have,” she said. “He fully understands what that means,” Bullock replied. “He doesn’t understand why people judge each other based on color of the skin, but he knows that they do.”
