Vacuum-Phobia

Tonight I got the vacuum out (like I do often), turned it on and watch by Son be terrified for the first time. Of course he's been upset before, but this is the first time I have seen him truly scared! I turned it off and went into his room, loved him and played for a while. When we left the room to go back down stairs, he was looking at the vacuum, as we past it in the hallway, and clinched my arm tight. Poor guy! I hope this phobia doesn't last long.
