She is 3.5 and puts her hand down her knickers quite often at the moment (like yesterday in the middle of the school fete while everyone was looking at the children!).
I have always tried to not differentiate parts of the body but this is getting a bit much.
So tonight I told her she could only do that in her room. Not sure if this is the right thing to say.
I take it it's quite common behaviour for toddlers?
