Yesterday, I took care of a friend's sweet daughter while she and her oldest went on a field trip. When she came by to pick her up, we talked for a while about swapping out watering each other’s gardens when we are on vacation this summer. I realized how lucky I am to have a friend to swap out duties like this that would otherwise cost a significant amount of money.
Talk to a close friend about swapping out date nights, occasional baby-sitting, watering while away, or pet sitting. Usually friends are more than happy to do so when they know that the deed will be reciprocated for them. Be sure to avoid abusing the kindness and offer to reciprocate as soon as you can.
