Is it inappropriate for a father to kiss his 4-year old daughter on the lips? Not some long lingering romantic snog. A peck when saying goodbye. The reason I ask is because a woman told me it was inappropriate for an adult to kiss a child on the lips. I told her the child was 4-years old and my daughter. She said; 'Ask anyone!' So I am. My opinion was that the woman was excessively paranoid and overly-sensitive to an incredible degree and that anyone seeing something wrong in a father kissing his 4-year old daughter had a sick twisted imagination. Am I wrong?
