6yo DS, quite highly strung and easily scared by the most mild peril in films/books - so we don't watch/read anything that might trigger.
For a while, he's been saying that he feels like someone is watching him. He's scared to go into parts of the house without someone with him and he's scared falling asleep in his room at night.
His two younger siblings have no issues. He's always been like this but it seems to be getting worse.
Anyone else had this? Any advice?
