not really sure where to start but wanted to know if anyone had any advice from similar situations as im struggling to think of what more i can do practically,
my wife and i adopted brother and sister around 5 years ago both present with attachment disorder and initially took a lot of work for her to accept me as a caregiver, my daughter is now 9 and a short while ago i found that she had been trying to search for "boobs" and "sex" on youtube using the app built into the tv however due to me putting parental controls on their were no results, we tried to discuss this with her but constantly came up against "i dont know why i did it" we bought her books about the bodys development and had a chat with her about the things she had been searching for were not safe having gone through the books with her and having the "birds and bees" chat with her initially seemed to work however last week we were at a realtives house and allowed the kids to play on phones for 30 mins and when i got home i found that i had notifications from instagram which i have never used before, from checking it appears that my daughter has logged into the app using facebook login and began to follow some sexually explicit pages, the most concerning is that she appears to have sent a private message to one of the pages the content of which is " hi can you have sex with me ill sho u my willy" i have asked her about the message and again i get the response "i dont know why i did it" she is well aware that she doesnt have a "willy" as a girl and dont know whether she has tried to make the message appear as though it is from me as its my account, we have tried to talk to her and identify the reasons for this but she cannot explain and im at a loss as to what to do next. tia
