Teaching purity to my 4 year old daughter

My daughter Tappy, 4, started gyrating and singing "Shake your butt" yesterday. I looked at her with disgust and said, "What are you doing?" She stopped and said, "Nothing." She had that look of guilt. So, I asked further, "Where did you learn that?" "Nowhere, she responded. "Tappy, you have to be modest and not act that way." I explained. "Yes Daddy", she replied. Purity and chastity is a natural habit and even young children can understand it. It is the way of God and those way can be taught, must be taught if they are to grow in the path of righteousness. The picture below is a woman who probably does not know or was never taught the concept of purity.
