Sophie in Toronto has a Plan. She doesn't want two-year-old Pascal to get the idea that Halloween is a candy-grab, so she's planning to dress him up in a costume and take him out into the street with a basket of candy to give OTHER children.
"You see" she explained "maybe - probably - he'll get a few bits of candy back, but I think it's a good idea to work on the concepts of generosity and giving instead of receiving, don't you? I think we'll keep it up until he's about six years old. And THEN we'll do trick or treating on our own."
Good luck with that, Sophie. I await the results of these experiments with great interest.
Last year I was in Vancouver for Halloween. The baby who lives next door to Mum and Dad was less than a year old, and far too small to have any interest whatsoever in candy, but the occasion gave her parents an excuse to dress a baby in a dinosaur costume, and a sugar-free trick-or-treater knocking on our door gave Mum and I an excuse to have a little baby-scale Halloween fun.
