I'm not really familiar with any of this, just thought I might browse online to see if I could find something to help her out and found this site. Hoping for a little advice with what to do here...
A little background, my sister and her fiancé have 2 kids - Tyson who just turned 2 and Ava who is about 8 months now. Moved into their house shortly before Tyson was born.
When Tyson was about 9 months old, they noticed he would play/communicate with someone in his room occasionally. Lots of 2 am crib parties too. Recently it's gotten to the point that he screams at something "NO NO GO AWAY" and will put a pillow in front of his face and hide. Absolutely terrified sometimes. My sister has set up a baby monitor with the camera in his room, and sometimes when she turns it on she'll catch a brief glimpse of a shadowy figure - sometimes it's just standing there and sometimes it moves across the room. This is only in Tyson's room, he's even moved rooms and Ava has his original room but they haven't noticed anything go on in her room at all.
Now there is some tension at home - I think there would be in any household with 2 kids under 2, but I think there's more negative energy there than my sister and fiancé realize. I talked with someone here at work and she says sometimes these things could be attached to an object. Maybe a second hand toy brought into the house for him?
How should she deal with this? Is this something that they should look at bringing someone in? Like I said, I'm not familiar with any of this so please keep to the KISS mentality (keep it simple, stupid!) for me.
