Is this common for 5 year olds, my children arent this age yet so I dont know whats to come, but its a really sad to hear, her Mum is really upset, she has obviously brought it home from school, Im guessing she has no idea what it means and probably neither does her 7 year old sister. Obviously you cant stop them from picking up bad language from school but does anyone have any advice on how to avoid them repeating it at home.
