The "Steve Jobs" actress, who has children Mia, 15, and Joe, 11, from her past marriages and Bear, 23 months with spouse Ned Rocknroll, places restrictions on the gadgets her kids are allowed to use, reported Female First.
"I enjoy being terrible because it means I never have to get a computer. I don't have one. We have no social media in our home.
"My daughter has only just been given an iPhone but there are big restrictions on that, she has to hand it in at night and it's switched off. Children have to have a childhood and I do worry that exposure to social media and all these devices could get in the way of them just knowing how to club a tree.
