To keep the house picked up, teach some responsibility, and keep my sanity for the summer, the big boys now have chore charts. I found these customizable/printable charts at iMom.
We haven't set a specific number of stickers or anything, but the boys know they will be able to earn some extra fun stuff by being more responsible. This week is sort of a trial since I am still working. We will see how they do, and then pick some rewards.
