Jessica Alba felt like she was being ''judged'' when she first became a mother.

The 'Sin City' star - who has daughters Honor, seven, and Haven, three, with husband Cash Warren - has admitted she was worried about the opinions of other mothers when she gave birth to her eldest child.

She shared: ''Doesn't it feel like the mean girl thing from high school sort of just transforms into adulthood through motherhood? I think it has to do with hormones, right? ...

''And then your hormones go crazy again when you're pregnant and having a baby - and even when you're breastfeeding. And I feel like maybe it's just all those hormones, and people don't know where to put their energy, so they just start clashing.''

Whilst the 34-year-old beauty had a bad experience in the past, she refuses to let other new mothers feel the same way.

She told Yahoo! Parenting: ''Now I'm one of those moms that gives you too much advice that you may or may not want. I think the biggest thing is that what works for you, or what works for your friend, isn't going to work for everyone. There is no right or wrong.

''I have two very different girls. The way that I parent one is different than the way that I parent the other. There's no cookie-cutter way of going about it. I think we as women - and as moms - need to show younger girls that we support each other no matter what and to try and not be so judgmental.''
