Look for service opportunities that allow your family to serve “with” people in need rather than doing things “to” or “for” them. As a part of this, encourage your children to look for things they can learn from the people they serve.
Consider designating a regular time for family service (“Service Saturday,” anyone?), as well as taking advantage of everyday service opportunities within your family, as described in Teaching Our Children the Joy of Serving Others by Lisa Jacobson on FortheFamily.org.
Check out the short article Creating Space to Serve on TheBanner.org, in which Lisa Van Engen explores how parents can “be intentional in teaching children and young people to serve rather than to be served, to look outward instead of inward, to give rather than to consume.”
