Narrative: I was the Captain for this flight and I was away from the Cockpit sleeping on my required break.  When I returned to the Cockpit to start back to my flight Duties; I was informed from the acting Copilot that they had dealt with an unintentional None Crew Person entry into the Cockpit.  Although shocked; after listening to how it had happened I could see how it might have been able to.  The Flight Attendant misunderstood the FO's request to tell his son that they were passing near Greenland for him to take a look.   When I later went back for a washroom break just prior to the landing at ORD; I also talked with the Flight Attendant about his required procedures with the entry into the Cockpit and the Cockpit Door opening. Also reminded him if he ever felt that a request of that nature is what he heard; he best clarify and to just speak up and ask if that was what was asked of him.  Also knowing his responsibilities and training; to just refuse such a request. Had he just asked to clarify; or refused the request none of this would have happened.


Second narrative: We were at cruise during the second portion of the scheduled pilot break. The Captain was on his break and myself and the relief FO were in the cockpit. As we were approaching Greenland; I called the forward galley to inform Flight Attendant that the weather ahead was nice with good visibility; since he had asked me earlier if we were going to be able to see Greenland. He asked if he could come up to the cockpit. I told him that would be fine; since this would give me an opportunity to take a lavatory break after he came to the cockpit. He said he would call back when the area was clear and he would be ready. The relief FO then called back to the forward flight attendant station and asked whoever it was that answered the phone if they would inform his son who was riding in the cabin that he look outside his window to see Greenland. Subsequently; the Flight Attendant called to say he was ready and would be at the door. I then went to the door and looked out the door viewing port. It was dark outside the door; but I could see his face as he was close to the door. I didn't see anyone else; as the son was much shorter. I then opened the door and stepped back. At that point; the son had already stepped in and the Flight Attendant was following him into the cockpit. As the door was closing behind them; I recalled our security training which emphasized keeping the door open as short a time as possible (three seconds ideally) and realized the safest thing to do was to close the door and sort it out with the cockpit secure. We then called back to confirm the area was still secure and arranged to have them exit the cockpit as quickly as possible. After discussing the error; it appears to have been a misunderstanding about bringing the boy to the cockpit versus pointing out the view.


Synopsis: A B767 crew member's child was inadvertently admitted to the cockpit in flight.
