Just that really! She's the middle of 3 girls. My eldest two have an iPad for an hour on a Friday evening, they get a warning 10 and 5 mins before they have to be put away.
Tonight my darling little daughter told me that I am a 'horrible bitch' when it was time for the iPad to be put away. She has a short temper and can be difficult at times but no worse than any other child her age. This is definitely a first for her and I don't know where it has come from! 
She got a real telling off and sent straight to bed, I'm at a loss really what else if anything I should do.
