My 2 year old son talks to my dead grandfather and my mother in law that is also past on? Is this OK or should I get him help, because he does it in the middle of the day and when he's sleeping and its creepy me out!? What should I do?? :confused::eek:

Ooh no! The in-laws! Call the authorities! :eek:

Just kidding.
I'm not so sure about talking to spirits. I do not deny that they exist in one form or another, but I don't know about communicating with them.

At first I would have said it could be a coping mechanism. Little children have vivid imaginations, and I've seen something similar done as a way of dealing with death.
Did he ever know his grandparents? Was he close to them, attached, if you will?

But, then you said he does it in his sleep. I don't see how he could be doing this in his sleep, but the subconscious mind is very mysterious.

Others may have something else to say. That is just my opinion.

Don't discourage him. If he is seeing their presence or hearing them he may have paranormal abilities.
If he is not seeing or hearing them it may just be his way of coping with his lose.

I would maybe ask him some questions to figure out which it is but I wouldn't discourage him

Had to spread the rep N0help, but I agree.

Unless there are some negative consequences from this, then there is no reason to stop this behaivor anyway.
