M.V.
My husband likes to help the kids cook things for our neighbor friends. Things like bread and cookies. Then, dressed like ninjas, they deliver them and ping-pong dash. Of course, the note says it is from us so they know it is safe to eat. Gives me a break and helps them serve others.
We also run a lot of our excess veggies from our garden to everyone around the neighborhood too and flowers to the little old ladies. Hope this adds some ideas of how to spend some of the excess freetime over the summer. We have 5 kids from age 10 to 1.
