Found pictures of my daughter in a bra (bed selfies) on her phone. How do I handle this?

She’s 12 gonna be 13. It doesn’t appear that she sent them to anyone, but just looking for some advice on how to handle this best. We are going to confront her, but I don’t want to push her into it more or create some serious trauma. Thanks in advance. via /r/Parenting https://ift.tt/2nPxqHB
