My 14yo dd (only child) is home alone until around 6 after school. I remarried around 7 years ago(in case that’s relevant and so as not to drip). She is always in our room when I’m at work. I’ve hidden my vibrator in a suitcase and sex books in with old clothes but I’m concerned about her finding adult things. She claims not to but it is clear things have been moved and she has form for doing that. We have a latch lock on the inside (as even at 9, 10) she was still coming into our room without knocking. Replacing the lock for one that locks inside and out seems to be taking it too far.
Any suggestions?
