...raises hand...
don't hate me, ok?
My three major organizing MUSTS-
1. Get rid of as much stuff that you own as possible.
2. Make sure everything you decide to keep has ONE place where it belongs, and it is in that place if no one is using it.
3. Pick ONE day a week that you do a particular chore.
For example, for us- sweeping is Mondays, trash is Wednesdays, Laundry is Saturdays.
OK, I know you have sooo many more kids than I do, but I swear by these rules. They saved my brain!
