My son is getting scared of so many things

Hello all,My son, who is 6, has had quite a few of the usual fears growing up. He's scared of the dark and monsters on occasion...Usual stuff.The thing is I managed to explain how zombies and ghosts aren't a problem as even if they were real they'd have to get past me in the house first (tough dad me). He's still scared of the dark but I'm gradually dimming his lights at night which is getting us there slowly.A big problem has occured now that he saw a video on the kids YouTube app of someone playing Five Nights at Freddy's and he's been absolutely petrified of it since. He won't go anywhere alone which means his toilet training (which was also recently a problem) has gone out of the window as he doesn't want to go as it would mean going upstairs alone.I've tried explaining the difference between reality and this game but I'm struggling. Does anybody have any advice at all?Really appreciate it. via /r/Parenting http://ift.tt/2kiQF8f
