~ Don't allow children to go without an adult, even next door. My cousin was raped when she left her home to go next door so they could see her costume. A man accosted her in the bushes between the homes and no one saw a thing.
~ Don't allow children to eat anything until it's been brought home and checked by an adult, tossing any opened packages.
~ Keep costumes safe by using makeup as much as possible rather than masks.
~ Keep costumes easy for a child to wear and get out of, no dragging parts to get caught up, or costumes too bulky to allow a child to move freely.
~ Have something reflective or lit up on each child so they can be seen in the dark. I bought some "glow necklaces" in the Dollar section at Target today, 2 in a package for $1 and they were available in several different colors.
~ Toss any homemade treats unless you know the person who handed them out well, or they're marked with their name, and address.
~ Stick to your city or town's Trick or Treating hours. Years ago my friend and her children were met at a door by a man in his BVD's, he said they were early (they were by 20 minutes) and he hadn't had time to put his pants on. My friend did call the police and they said 1) it was his home and he could answer the door however he chose, (!) and 2) they were early and shouldn't have been there.
~ Don't go into unlit areas.
~ Consider going to a block party or festival instead of trick or treating, they all hand out goodies as well ; )
