I agree with the "pay it forward" answer. As a parent in a community with children and parents, there will be MANY opportunities to "pay it forward." A child will get sick and someone will need help with their other children. A family at your child's school will experience tragedy and a drive will be taken up. Volunteer opportunities will abound as well. Make the decision today that you will respond "yes" as often as possible to these community efforts, just as the community has done for you. Express your sincere gratitude to everyone who has helped, remind them that they can come to you if they need something, and then engage in the practice of "yes." It is how communities thrive, and it is lovely to know you are a member of a good one.
