4.7 DD grinding

[TinselTess]

She has been grinding for a few months now - at first I didn't notice, but then it because increasingly obvious as she kept asking to play the same game and was clearly rubbing her bits against a cushion/toy/ etc. I asked her why she did it and she said it felt nice. I didn't want to embarrass her, I am sure sexual exploration is part of normal development. I explained to her that rubbing or touching your parts were something you do privately in your own room. She seemed to understand, but the problem just seems to be getting worse and she is doing it in front of friends and family (some of who have noticed, but are too polite to say, I am sure). I catch her doing it several times a day. I just quietly remind her to go upstairs if we are alone - or just give her a knowing glance if in company.
I suppose I am worried as I am not sure if her interest in this is normal and I am not sure I am going about it correctly. Secretly I suppose I am really worried that she is doing this because someone, somewhere has done something unspeakable to her. My logical brain tells me no, she is displaying normal behaviour, another part of me is panicking.

Any ideas???

DD3 does this sometimes, rocking on the edge of her chair. We tell her to stop; if she doesn't stop, we take the chair away.

It's something they grow out of eventually. DD3 doesn't do it at school; she only does it at home absentmindedly when she is distracted or engrossed in something else and has to be reminded not to do it.

It is not at all uncommon - really, please don't worry!

It feels nice, that's all. To her it's not 'sexual'. If it felt nice to rub her elbow or twirl her hair you wouldn't be bothered about doing it in public - for her it's the same thing, so it's hard to remember to go to her room to do it.

Of course, you are doing the right thing reminding her to go to her room to do that - but it will take time before she does that unpromted every time because to her it's not private or sexual or whatever - so probably seems 'odd' that she can't do something nice wherever she is.
