Q. Re: Playing Doctor: I would add this word of caution. Today these sorts of things are taken EXTREMELY seriously. Last year my family went through hell when my daughter mentioned playing doctor with her older brother to a friend. My children would have been approximately ages 6 and 4 (we never were able to determine this exactly; they may have been slightly older or younger) when it happened—there was some showing of parts to each other. This friend, appropriately so I guess, told her mother. The mother then mentioned it to the school principal, a mandated reporter. The department of child and family services was called. An investigation ensued that involved two home visits and interviews with my children. In addition my daughter had to undergo a forensic interview with a child psychologist; my son had to give an audio recorded statement to the police. After the investigation, the entire case was dropped, but the entire process was one of the most stressful experiences of my entire life, made more so by that fact that you cannot talk to anyone about it.

What happened was indeed child abuse. By all the adults that should have known better.
