A bit of context: I think AP should keep her birth control pills out of the sight of my kids (10, 8, 6) during working hours in her room, as kids often go in and she often invites them in. I've asked her about this several times but it hasn't happened, and I have taken to just slipping them into a drawer when I pass by. They always come out again to sit on the side. A few days ago, my daughter asked what they were (I was in the kitchen, they were in the APs bedroom with the door open, had been doing some drawing together), AP said 'medicine', DD said 'what for?', and AP said 'they're to stop me having a baby when I have sex with my boyfriend'. I really think this is unacceptable for a host of reasons, also DD was a bit shocked and upset herself (wasn't the answer she was expecting at all!). I had fairly gentle words with AP after, but AP's reponse was her usual throw-it-back-at-you one of, 'What do you expect me to say, how am I supposed to know how much they know about that kind of thing?' Does anyone have any experience of this kind of thing, should I put something in my 'welcome pack' (which look pretty forbidding as it is) specifically about avoiding touching on sex-related issues with the kids yourself but referring them to parents instead? Has this ever happened to anyone else - AP also keeps just-short-of-explicit pictures of herself and friends pinned up on walls, and when I raised an eyebrow, she raised one back...
