Charlize Theron can't "handle" anymore children

She said: "I knew a long time ago that this was going to be my family and I am so blessed and lucky that this is my family. As of right now, as a single parent this is what I can handle and I think it's a good thing to know what you can handle. This is perfection for me. I feel very blessed."

However, the 'Tully' star has to remind herself how lucky she is when her children's meltdowns push her to breaking point.

Speaking to E! News, she explained: "My oldest [Jackson] can definitely get into a state pretty quickly."

But the blonde beauty accepts that everyone has bad days.

She said recently: "A child in my twenties was the scariest idea I could think of. When I got to my thirties, I was so ready. But there's a moment where you're like, Oh God, I hope once I have my kids, I'm still going to want to be a parent this much. I have bad days. I make mistakes. Going through the tantrum stages when they're such little assholes. And they choose the worst moments. It's a lot for one person. But after six years of having my two nuggets, there's not a day when I wish I hadn't done this."

Charlize adopted Jackson in 2012 and August in 2015 and found the process of gaining parental rights a challenge.

She said: "I struggled mentally through the adoption process. Some of the lowest points in my life were dealing with the first time I filed; it really took an emotional toll. There were situations that didn't work out, and you'd get attached and have all your hopes up and then just get crushed. So I was in a different mind space. I had different needs."
