The 32-year-old actress - who delivered son Kahekili, her first child with boyfriend Norman Kali, in May - opted to have a home birth but she wasn`t prepared for how long she would be having contractions.
She told TV talk show host Jay Leno: "We decided to have the baby at home because we wanted it to be a natural birth, and it turns out that it was 30 hours of natural.
"Eight hours of pushing, that`s the part that men don`t understand. Women go, `Oh dear, oh, dear God, eight hours of pushing?` And the men are like, `OK, eight hours of pushing.`
"After about five hours of pushing, my midwife and my birthing assistant said, `You know, we have a few suggestions.` And I was like, `Really? After five hours of pushing you have a few suggestions? You couldn`t have told me five minutes in?` "
Despite the lengthy labour, the former `Lost` star insisted the painful experience hasn`t put her off having more children.
She said: "If I wasn`t working right now, I would be trying. I want a brood. How many are on a basketball team?"
