Here are some ideas for remembering Advent in your home:

Gather the family around an unlit advent wreath at supper each night. Dad should pray, thanking God for the gift of His Son and asking for His help to follow His example. On the first week, light one of the purple candles. Read a short passage from the Scripture.

Jesus is the Prince of Peace and, in the sermon on the mount, He taught us, "If therefore you are offering your gift at the altar and there remember that your brother has anything against you, leave your gift there, before the altar. First, go your way and be reconciled to your brother, and then offer your gift." Why not take this time to encourage your family members to make peace with each other?

Then you could all pray the Lord's Prayer together. Then let dad say the priestly blessing over the family: "The Lord bless you and keep you; The Lord make His face shine upon you, and be gracious to you; The Lord life up His countenance upon you, and give you peace."

Then put out the candle for the next night.

The second week, light the first candle and a second purple candle.
The third week, add the rose-colored candle.
The fourth week, all four colored candles.
On Christmas Eve and Christmas Day light the central white candle.

Another idea, why not decorate your Christmas tree throughout the month of December with Jesse ornaments? The children could make them during the day. You can find many ideas for Jesse tree symbols by searching Google. You could use the Scripture reading that goes with the Jesse tree symbol for your family reading each night after lighting your advent candles.

You probably have a nativity that you set out. Why not set it out a little at a time:
The first week, just the manger.
The second week, add the animals.
The third week, add Mary and Joseph.
On Christmas Eve, set out Jesus and the other figures.
On Epiphany (January 6), set out the wise men and camels.
