"It was the furthest thing from my mind," Mendes told the publication about being a mom. "[Then] Ryan Gosling happened. I mean, falling in love with him. Then it made sense for me to have...not kids, but his kids. It was very specific to him."
"We're just starting to get out of survival mode," she continued. "I'm starting to feel like a person again."
Gosling and Mendes worked together on the 2012 film "The Place Beyond the Pines." According to the "Ghost Rider" star, something changed a year later, following the birth of Amada. After two decades in Hollywood, Mendes said she was ready to put her energy solely into being a mother.
"I felt a lack of ambition if I can be honest," she said. "I feel more ambitious in the home right now than I do in the workplace."
"Every day is such a learning experience -- they challenge you in so many ways. Like, I'm their mom," she added. "I have to rise up, and hopefully, most of the time I do, but sometimes it's definitely maddening."
Mendes, who said she learned about her gratitude from her own mother growing up, was asked about how she plans on raising two young girls in the same way, despite having both parents in the limelight.
"It's definitely a concern," she said. "Not only are we in the industry, but the whole fame component is super scary when you try to raise your kids."
"What I try to emphasize is that I don't let them see me put attention to how I dress," she added. "They've never seen me get ready for something; they've never seen me at work. Which is fine, for whoever wants to do it that way, but the way I keep it normal is by not letting them see me in these situations. I'm just Mom. And I'm more than happy to just be Mom.”
