I feel like such an idiot. DD (11) has Instagram and Whatsapp. I was looking through them on her phone and whilst it's mostly innocent pictures of cupcakes and Dutch plaits, there is some inappropriate stuff in there too. A boy in her close posted a photo of himself in the bath for instance and there's quite a lot of bitchy remarks. I hadn't realised the age limits for both. How do I claw back some control? We're in full-on pre-teen mood swings and the whole emotional roller coaster of end of year 6. I feel like I'm walking a tight rope with her. Please help.
