I suggest keeping these supplies where you actually use them: under sinks (child-proofed, of course) or at the very least on each floor of the house or each end of the house.
Get these at a discount store to put in a caddy per bathroom (or floor level):
"Small Things" Supplies
Wisk broom/dust pan
Optional: Pop-up wipes (love these)
General cleaning supplies to have:
Tools: brooms, mop, vacuum
Starting fresh with the tools you need will give you power to spend time on the things you really WANT to do, instead of feeling victimized by all the housework.
Remember, Sanctuary in the Small Things is not just about cleaning, but it's about caring for your home and the people who live in it. It's part of showing love AND helping your family members belong to the process of homemaking. I'm all over that.
POINTS: 40 for taking stock of what you have and start getting everything together!
