  there is a method to do this on every subclass of DisplayObjectContainer (i.e. Sprite, MovieClip, ...). From the language reference:

  Determines whether the specified display object is a child of the DisplayObjectContainer instance or the instance itself. The search includes the entire display list including this DisplayObjectContainer instance. Grandchildren, great-grandchildren, and so on each return true.
  Parameters
  child:DisplayObject — The child object to test.

  Returns
  Boolean — true if the child object is a child of the DisplayObjectContainer or the container itself; otherwise false.

  Example
  The following example sets up a number of Sprite objects and adds some to the child list of others. (A Sprite object is a type of display object container.) The relationship between various objects is shown by calling the contains() method:

  import flash.display.Sprite;

  var sprite1:Sprite = new Sprite();
  var sprite2:Sprite = new Sprite();
  var sprite3:Sprite = new Sprite();
  var sprite4:Sprite = new Sprite();

  sprite1.addChild(sprite2);
  sprite2.addChild(sprite3);

  trace(sprite1.contains(sprite1… // true
  trace(sprite1.contains(sprite2… // true
  trace(sprite1.contains(sprite3… // true
  trace(sprite1.contains(sprite4… // false
