My daughter always has her finger in her nose!!!
I do not know what to do to make her stop! Each time that I catch her, I make her go wash her hands and tell her that she needs to go to the bathroom and use a tissue.
I have explained that we only do that in the bathroom. I have asked nice and calm. I have used time out. Other people have told her. I explained that it is gross and spreads germs so her friends will not want to play with her with gross hands. We even had the tv on when a disney show (Jessie? I think. It was something that we don't watch) had a older girl telling a younger one to make friends with another younger one at the park. Then the young girls had "ewww gross she picks her nose!" and the screen paned to show the kid picking her nose and everyone appalled by it. I rewinded it and made her watch it.
It's so bad that I catch her doing it during story time, children's church, everywhere! It's been going on so long that if it were a phase then it should be over with by now! PLUS she eats them!
I have tried every method that I can think of and nothing has worked!
