Gee ... that sounded pretty snarky! Does Santa come to your house? Does he see kids are that both naughty and nice? Does he bring gifts to naughty children?
Well ... Tinkerbelle will be filling in for Santa in a couple of weeks for my DD and her cousin. We are treating my sister's daughter to WDW so she can be a companion to my DD. The problem is that the girls only get along about 23 hours a day with about an hour of fighting and "That's not fair!" and "You care for her more than me!" thrown in for fun

. To help smooth over the rough spots, Tinkerbelle will watch over the girls and if they are good all day, she will leave them a present under their pillow along with some pixie dust. Since Tink is just a tiny fairy, the present itself will also be very small but the girls will get a kick out of it. My guess is there will be a huge attitude adjustment when Tink leaves only pixie dust behind one morning because they were particularly rude the day before.
FWIW, a rewards system works for many, many parents. I reward with paper clips for everyday good behavior and cooperation in situations that would otherwise make my DD lose it. Her paperclips can be turned in at any time: a few for something small and a lot for a bigger item. My DD is a strong-willed, spirited child. The lure of the paper clips motivates her to get a hold of her temper and cooperate and it has worked wonders for our family. Many other families call this an "allowance", but at 5 she knows no value of money.
Again, I'm glad that you have a solution that works for your family ... but I wasn't snarky about your choices. I don't know why you feel the need to be snarky about other people's choices.
