dd(2.10) doing 'special tickling'

[sunglasses]

I will assume I dont need to go into details about the sort of 'special tickling ' she is doing to herself but I dont know how to handle it. Obviously she thinks its great and has started to do it quite frequently, even when we have relatives here or at other peoples houses which I obviously don't want to encourage. I don't want to tell her off butI need her to understand its not acceptable to do whilst lying on the sofa next to her grand-dad!
Please help me out anyone with similar experience. She is the youngest of my 2 daughters and my nearly 5 year old doesn't do this at all.

I think you just need to tell her she has to go to her room and it isnt something to do in front of other people?

I dont mean send her to her room as punishment btw

Yes tried that but I cant always monitor it and also she shares a room with her sister. I think she is still a bit young to realise that she needs to do it in private but I will definitely try and pursue that idea with her.
Any other advice?

I know you will have tried this already...but I think you will just have to try and distract her with something else if you see her doing it.

My friends little girl (3.2) is also doing this - alot! She's dealing with it by saying that it's an ok thing to do, but that she should do it in her own time and whilst it's just her. The problem is that the young lady in question has realised it is something that can get a reaction and therefore does it just for that reason sometimes! In which case we are often just having to dismiss it with a "leave your bits alone love".
Hoping the phase passes and doesn't make grandad blush too much!

Yes I hope its a passing phase. I do try and distract her and have had the 'do it in private' conversation to which she just says well go away and leave me alone! I don't think she is doing it to get a reaction, its just a newly discovered interest
Anyone had a previous experience and it has just been a passing phase? (well at least in public!)

Put her in dungarees?

She is in clothes and actually still in a nappy but this doesn't stop her. she does it outside of her clothes if you see what I mean.... and today I found her humping her older sister on the stairs which is obviously something I need to prevent!

Hahaha to humping older sister! My ds used to do this a LOT but now a year on it is not as frequent. He is almost 5 and now and he now humps his blanket in private in his room. Lol. Was embarrasing around guests but don't make big deal of it and just distract and ask her to do in private. Xx

DDs 1&2 tickle each other! Nothing you can do except remind them that 'bottoms are private'.
