Light a candle
Lighting candles at mealtime naturally quiets things down and encourages reflection. (Unless your kids are toddlers or pyromaniacs, of course.)
Expressing gratitude before you eat -- such a simple way to pause. No need to include religion if that's not your thing
Friday night dessert
We make Friday nights special by serving a treat. It encourages our kids to invite friends over instead of making plans, and it takes dessert out of the "daily" realm and into the "special."
Change of venue
Dinner in the living room. Sleepover in the basement. "Predictable variety" is exciting.
Weekly family fun night
Movie night, game night, quiet reading night...whatever you enjoy.
Scheduled phone calls
Regular calls to the grandparents or far-flung friends maintains connections and adds rhythm to the week.
Coming of age rituals
Monthly growth chart recordings, weekly allowance...these small actions let a kid know she's growing up.
10-minute bedside chat
Even my teen still loves this nightly ritual. Many observations of the day come out at this time.
