Jessica Alba believes she is a less "irrational" mother second time around.

The 30-year-old 'Spy Kids 4' star - who has daughters Honor, three, and Haven, eight months, with husband Cash Warren - insists she is nowhere near as neurotic following the latest addition to the family.

She explained: "I feel like most of my irrational, overprotective, and weary new mom behaviour evolved into a more easygoing, laid-back approach with my second child.

"I've never been a true 'helicopter parent', but I've definitely stayed awake for endless hours doing research on everything I could do wrong. I often made more mistakes trying not to make any mistakes."

Having learned to take each day as it comes, Jessica admits parenthood is a lot more enjoyable without the worry.

Writing on her iVillage blog, the actress said: "With Haven I'm more relaxed. I try not to let every cough or bump on the head freak me out because Honor made it through infancy in one piece, and I trust Haven will too.

"This calm attitude has definitely made adjusting to life with two kids easier and more fun. It may feel impossible trying to juggle it all, so don't hold yourself to the unrealistic standards of being a supermom."
