Don’t worry
Oh, we would definitely be worrying a lot if we heard a stranger in the same room as our baby speaking to it. We think that we would run upstairs with a weapon ready to attack the stranger and save our child. But what do you do after you enter the room and no one is there?
We think that if this were to happen again, it may be time to move houses. The last thing anyone wants is a ghost to be wandering around and haunting everyone. If these people can not afford to move, then call a priest, it may be the only option you have left.
