My children would say I nag them about thinking of other kids, remembering to share, pulling out their own money to drop in the collection basket. I figure they have plenty and they need to give something to kids who don't. I remember, after one of my long-winded lectures on community service, my son more or less challenged me to practice what I preach.
Kids have a way of doing that.
So, we started doing community activities as a family. Now, the kids organize and participate in service projects with friends, too. Time, as precious as it is, is probably the biggest gift any of us can give. It's easier and no less valuable, to write a check. But I've seen that coming face to face with people and their needs is the best way to teach my children how to give back.
