Actually, I have. The girls have a special, you-can-write-on-it bear that I once called "Sick Bear" to help my older girl sleep when she was ill once. So eventually Sick Bear became dragged out of the toy chest anytime any one of us is ill. I mean, if I'm sick I don't run and get it, but one of the girls will bring it over to me in bed as a sign that they are concerned.
So last time I was laying there with Sick Bear I realized all I've really created is a freakin' germ sponge that we pass from family member to family member. This was not well-thought out of me.
