Drew Barrymore's new baby has had a ''calming'' effect on her life.

The 'Blended' actress - who already had 19-month-old Olive - welcomed her second daughter, Frankie, into the world with husband Will Kopelman on April 22, and despite being exhausted, she is thrilled with their new addition.

Asked how being a mother for the second time feels, she told E! News: ''Better, just on every level. It's so much more work, but it is so much more calming in a way.

'''Frankie is sister,' Olive says, and she is into her and it's amazing, life is so good.''

But the blonde beauty, 39, is suffering from a lack of sleep.

She said: ''Every night at 10pm when I get in bed, I've never been more excited to just lay down for a little while, and then you sleep for six hours if you're lucky and you're back up.''

Drew recently said she wouldn't let her children pursue a career in acting until they are at least 18 years old because she wants to protect them from potentially damaging things.

She said: ''I don't like the idea of young girls growing up with social media, because I know how sensitive they are. But there's no going back.

''If you totally shelter your kids, that's not normal, but I don't want mine to have mobile phones until a certain age.

''I will never let my children act. When they're 18, if they want to, but not before.''
