Kate Winslet has revealed she wished she'd been more prepared for the pressures of early fame, which she compared to 'having 55 babies in quick succession'.
The Oscar-winning British actress told the BBC News website that becoming instantly well known after the huge worldwide success of 'Titanic' in 1997 was 'difficult'.
"What I do wish is that I had had more support going through those early days," she added. "It's genuinely difficult.
She explained: "With things changing overnight, I wish I had known people who could have said 'this is what's going to happen'. I wish I'd known more people who had actually gone through that.
And despite Kate admitting she 'missed out' on her teenage years, the mum-of-three is determined her own children, Mia, Joe and Bear enjoy their childhood for as long as possible.
She told Radio 4's Front Row: "For me, and this is not a general thing, all that is important for both of my children, is that they have lots of things that they love to do, that they're active, that they can be who they want to be and not feel forced to be one thing or another.
"And to stay a child, really, for as long as possible. That, I think, is the hardest thing for kids now, they seem to grow up so fast, simply because there's so much exposure to the internet and the digital world.
"I mean we have none of that stuff. If I see another child under five playing on an iPhone I will cry."
Kate's new film, 'Divergent' is out in the UK on Friday 4 April.
