We have used Monster spray ( a spray bottle filled with water or some febreeze or anything else we could find at the time lol). A few weeks ago dd7 said "momma there's no such things as monsters.. you werent' spraying anything". BUSTED.. but she hasn't woken up with monsters in abut 2 years. At one point we had to remove anything in her room that had eyes. DD5 never had monster problems. He just doesn't sleep more then 7 or 8 hours and no matter how late he goes to bed is up at 6:30.
