Hilary Duff wants to stop ''mom bullying''.

The 'Lizzie McGuire' star - who has three-year-old son Luca with estranged husband MIKE COMRIE - thinks being a new mom can be ''isolating'' and is keen to stop mothers from ''judging'' one another.

She said: ''Even before you have your baby, you can start feeling the judgment. And, you know, becoming a mother and that whole process is so special and so magical really, but it's also very isolating.

''The biggest things that stand out for me was choosing to have an epidural. I felt very judged by some people. Also, once I had breastfed for a certain amount of time and I was starting to work and starting to supplement with formula, I felt judged then.''

The 27-year-old beauty also insists it is alright if you don't know all of the answers straight away.

She added: ''I think a lot of the times you feel like you should have all the answers and you feel like you should know how to do everything and nothing should go wrong.

''You put so much pressure on yourself, and it's really kind of a lonely place to be. So I think women and families need to boost each other up instead of, you know, bullying one another.''

Of her relationship with sister Haylie, who has son Ryan, she shared to Entertainment Tonight: ''I feel like we're good about just always listening to one another. Every experience is different.

''That's the thing and I even have to be conscious of it when I'm talking to Haylie. She'll be saying something about Ryan. I'm like, 'With Luca, this.' But then I'm like, 'Oh, Luca's a totally different baby than Ryan.'''
