Involve Other Caring Adults
As parents, we are their 1st teachers, and children are very quick to mimic what we say and do. If they're exposed at an early age to others who are also compassionate, loving, respectful people--grandparent, aunts, uncles, etc.--that gives them a solid foundation to be that way themselves.
We raised two boys into adulthood and they both turned out to be kind, compassionate young men who freely gave to charities. The credit isn't all ours, though. Others helped to shape them along the way, and we're also a very faith-filled family.
