Thanks for you reply Cranky Kitten - the same thought did cross my mind too - I have spoken about 'private parts' and things like that since she was quite little and have spoken to her a few times about it just recently and she doesn't seem to act any differently when I do but I know that isn't enough to decide that nothing might have happened - although my gut instinct tells me it's not that.

The other thing that crosses my mind is that a few months ago I went away for a funeral and she stayed with her Dad for 3 days and missed me alot - it was the first time she had really been away from me for more than a day and maybe that made her regress a bit? Maybe it changed her routine all of a sudden and made her feel really insecure because Mummy wasn't there - it was only a few weeks after that she started acting differently.

Thanks so much for the support!!
