She probably has ‘special permission’ like she claimed she did when she filmed other people’s children on yet another trip out!I’m actually surprised that she is allowed to film, nearly all of the sessions run by the children’s centre, where I am based, ask for phones to be put away.
One to respect privacy, but also so that parents are in the moment with their children. Sadly, this is something that she can’t do! Stop stalking your children and leave them be!
