Playing inappropriately like this with an otherwise good kid may indicate another problem as well. This type of behaviour would be normal in a child with a strong personality, but would be seen in normal play situations. These behaviours sound unprovoked and not like normal attention getting behaviours. I would seek some professional advice such as your doctor. I would also check with your local health authority. Often the nurses see such a range of behaviour that they could either point you in a specific direction or alleviate your concerns.
