In the comments section of the Christmas Mosaic post, Danae asked about prayers to accompany the Advent wreath.
I like to use prayers from Prayers and Customs of Advent and Christmas.
This page has prayers for the beginning of Advent, along with short daily prayers for each week.
This page has some nice prayers for very young children.
Some short Advent meditations are here.
A few recipes are here.
All of the prayers on this site are short and easy for families to use.
When we light the candles on the Advent wreath each night, we divide up the "duties" (which are seen by the kids as fun and privilege, thus the fighting over them which resulted in the division of duty.)
One child gets to light the candle, one reads the prayer, and one gets to snuff out the candle at the end of the meal (the antique candle snuffer we use makes this especially attractive.) This way, everyone is involved, duties rotate and everyone is happy. Some nights, though, everyone reeeeeally wants to light a candle, or everyone reeeeeally wants to snuff a candle out. So, sometimes, I must admit, we relight candles just for the fun of it, and snuff them out again.
Because we're easily amused, I guess.
Have fun. Because, as much as Advent is about spiritual preparation, it should be about fun with your family, too.
