Busy Philipps admits that her greatest fear is that one of her daughters will be sexually assaulted.

She told Mini Magazine‘s Summer 2016 issue: "My greatest fear and worry is that one of my daughters will be sexually assaulted in her life. I know the statistics and I will try to help by starting conversations early about sex and protecting themselves, but it scares me to no end.

"I really hope that meaningful steps will be taken on campuses and I hope consent becomes a part of sex ed in schools."

The 'Cougar Town' actress also revealed that she was overwhelmed with love after becoming a mother.

She said: "I figured [motherhood] would be like any other kind of love that I had experienced in my life, but it isn't. It's not something you can be prepared for. It's all encompassing and so massive that you feel like you might break at times.

"I called my mom sobbing when Birdie was a few months old and said, 'I'm sorry'. All this time, I had no idea how much you loved me …'

"Part of my brain is always taken up by how to protect them, keep them alive, be a good mom. Seriously, I was in a SoulCycle class and all I could think was, 'Is the upper lock to the gate and pool locked?

That's just your brain when you're a mom."

Meanwhile, unlike many Hollywood stars, Busy isn't afraid to admit that she relies on her nanny, Iliana.

She explained: "Nothing would be possible without Iliana and her family and their support. I mean that."
