hi there .one of my girls did the same thing and as a single dad i was at my wits end and didn,t haddle it at all well . she semmed to be happy about it and did it right up untill she left home . a lady freind of mine came up with an idea that she would do it to show her how bad it smelt and how messy it was but it did,nt seem to help much . she is married now and we don,t even menchin it any more so i don,t know if she still does it or not . i took her to the doctor when she was still little and he said she would grow out of it but that never semmed to be the case . as a child she would do it even in the car on a trip and my friend would have to help her clean up . we always had to take spare clothing for her .some times there would be times when i was so emmbaressed ..
