Parents who upload pictures of their children on social media could be sued by their sons or daughters under France's privacy laws.
Mothers and fathers face a year in prison and a fine of £35,000 if they are convicted of publicising details of their children's private lives without their permission.
'Children at certain stages do not wish to be photographed or still less for those photos to be made public.' Eric Delcroix, an expert on internet law and ethics, told reporters.
And adults who sue their parents for breaching their right to privacy when they were children could receive compensation, experts say.
In February, the French Gendarmerie - concerned about the security of children - posted a message on Facebook, which read: 'Please stop posting pictures of your kids on Facebook.'
