Zenhabits.net has a great entry on 25 ways to simplify your life with kids. I LOVE the suggestions and found that I actually do a few of these already. I like #8 and #15 especially. I think Arianna is old enough to start participating in family discussions. Even though Sunday is our family day when we don't schedule much except Meeting for Worship and get togethers with family and friends, I think it would help us to plan our special day so it's more purposeful and meaningful to all of us.
Enjoy,
