A mum says she's happy for her kids to tell her to "f*** off" as swearing is "natural" and "not a big deal".
Lucinda Hart, an author, allows her daughters Rafi, nine and Aelfrida, six say what they like when at home.
The 47-year-old knows, however, not everyone is as accepting and says the children don't swear in public, the Daily Star reports.
