Drew Barrymore finds it "shocking" that her father walked away from his family.
The 39-year-old actress - who gave birth to her second daughter, Frankie, last week - insists she is "OK" with the fact her dad John Barrymore wasn't around for her and her mother Jaid very much when she was a child but can't understand his actions.
She said: "My parents split up before I was born and my dad was just never capable of being a father. It's something I really accepted and became OK with early on.
"But it's shocking to me that someone can make that choice. As much as I accepted it with him, I could never accept it in a partner...for some people showing up is just not possible and that is incredibly frustrating.
"When you become a parent, and think about what kids need, it is very emotional."
The 'Blended' actress - who also has 19-month-old daughter Olive with husband Will Kopelman - is a hands-on mother and loves spending time just with her family.
In an interview conducted before she gave birth to Frankie, she told Red magazine: "I am loving being a mom..
"We spend every weekend together. We don't have a babysitter. It's just us. I can't wait to see how that's going to work out with the second one!"
Early in her pregnancy, Drew attended a cooking school with friends Cameron Diaz and Reese Witherspoon and is looking forward to furthering her culinary education this summer.
She said: "I really love cooking, it makes me so happy. But I'm terrible at it. None of it is effortless or sexy or even tastes that good for that matter, but I'm really working on it.
"I might travel somewhere to do it, and bring the family. I love cooking for Olive now, but I used to be Mrs Takeout.
"I've just never learned to cook in my life. Cameron's a great cook, and always has been. I'm just trying to catch up to that."
