RACHEL Weisz says cuddling her son helps her deal with stress.

The British actress — who raises Henry, 3, with fiance Darren Aranofsky — had some traumatic storylines to cover in her new movie The Lovely Bones and she says her family were the best antidote to a bad day filming.

“When I was making The Lovely Bones I had the perfect way to de-stress after an emotionally difficult day. Henry my son was a little one-year-old bubby when we were shooting it, so having a little one to go home and cuddle every night and play with was the perfect way to de-stress.

“You just forget any of the bad fictional things you have been thinking about all day Henry is so beautiful he takes your mind off anything.”
