I have six children (no that's no a typo). To help keep down the clutter my goal is to get rid of 25 items everyday.
25 items might sound like a lot but you would be surprised how many things you have laying around your house that you really don't need. I keep a large canvas duffle bag in the closet for things that could be donated. When the bag is full I know it's time to pile the kids into the (ridiculously oversized) van and take a trip to our local charity of choice.
This helps keep our busy home organized and we are giving back to the local community. A perfect family tradition!
