My DD1 has picked herself since she was around 2 years old and it's getting worse and worse. She runs her fingers over her skin - usually her face and arm looking for something that feels rough to pick and then is quickly gouged into a hole in her skin which is picked again and again and again. She always has scabs on her arms and face - such a pity. She has lots of scars already. I know it's a self-soothing thing because I do it too and I can't stop either. I can't find a plaster she isn't allergic to so I can't stop her picking. Does anyone have any advice?
