Drew Barrymore is "much more conservative" since becoming a mother.
The 40-year-old star, who has daughters Olive, two, and Frankie, 15 months, with husband Will Kopelman, insists she doesn't really miss being so carefree.
Asked if she is more confident now than when she was in her 20s, the actress said: "I was pretty darn confident in my 20s. I wore slips on the red carpet. Now I'm in muumuus! I was brave because I wasn't really thinking about anything, just being. Now I'm much more conservative, especially being a mom.
"If you gave me a chance to go back in time, I wouldn't take it. I'll never be ashamed of who I was, but I love how traditional I have become."
But Drew admits she no longer feels like herself since having children.
She said: "You're forever changed. It's a new you and it's a new set of mountains to clim. They're wonderful, but it's new terrain."
The '50 First Dates' star isn't sure whether she would like to have a third child.
She told In Touch Weekly magazine: "I'm good right now. The door's open, but I'm no spring chicken and I already feel like my life is in total abundance."
