Any ideas how to stop her doing it? Poor big sister is covered in nasty bruises where she has been bitten. I think she pushes her little sister around until she gets angry and bites but it's still no excuse. I've told the little one off and made a fuss of the big sister, Peppa Pig plaster and lots of cuddles, but it's still happening. She has also started pinching and pushing to get a rise out of her big sister. I'm terrified she's going to bite another child... Help!
