Sienna Miller initially found motherhood "really complicated".
The 33-year-old actress struggled to deal with being a parent at first because she was so affected by the tough birth of her daughter Marlowe, who is now two, as she endured a 27-hour labour and ended up having an emergency caesarean.
She said: "My birth went all wrong. I had my heart set on this natural water birth and I ended up, after 27 hours, having an emergency C-section.
"I spent so much time thinking about the birth and not realising that you take a baby home at the end of it.
"It’s a shock, of course it is, and some people find it really easy, but for me I found it really hard."
But the blonde star – who is engaged to Marlowe’s father, Tom Sturridge – has admitted being a mum was an advantage in her latest movie, ‘American Sniper’, in which she portrays real-life mother Taya Kyle, whose husband is the titular shooter Chris Kyle (Bradley Cooper), who was deployed to Iraq.
She added to Time Out magazine: "I think being a mother and playing a mother, yes, I understand motherhood in a way I just couldn’t before.
"I had a huge amount of empathy for Taya. To be going through motherhood on her own, not knowing whether her husband would survive every day, I can’t imagine how difficult that would be.
"Especially because that experience of motherhood for me was really complicated."
