I guess it's natural and part of exploratory development but DD1 lies on her front and puts hands down her pants and 'plays' with herself. She says it feels nice. Up to now I have ignored it but today she did it in the doctors surgery, on the floor in a busy waiting room.
What would be the best way to encourage her to keep this activity to times when she's on her own and not in a public place!
Like most 3 year olds if you ask her not to do something she does it twice as much and my attempts to distract her were met with a sly grin and ignoring me.
