I have two kids both have/had imaginary freinds. This friend seems to be a bad friend. Ask your son how he feels about the friend? Maybe he's telling you he wants privacy.
My daughter has a friend whom she blames when she's in trouble, however on our trip to the dr. she made mention of him and we ended up at CPS, so, becareful who you tell. You might fin dyourself in a really wierd situation. We rarely are apart from our daughter so I know nothing has ever happened to her.
sometimes kids can try to manipulte you by using theor imaginary friend, ie she knwe she would be getting shots, imaginary fiend appears......
Take it all in stride, focus on when the friend appears, and why?
My son was just lonely. His friend look like mr. rogers....
i ACTUALLY MISS HIM. LOL.
iT'LL PASSS, BUT i WOULD TELL cAM TO TELL HIS FRIEND TO LEAVE.
p.s. watch the cartoons he watches I suspect they may get this idea from them. maybe?
