Invite Jesus into your Christmas morning celebration. Below are examples of how some families celebrate Christmas while finding creative ways to worship and teach about its true meaning.
Use Advent to tell the Christmas story
Lights the ADVENT wreath before opening gifts and as you light it, you say what each candle represents. Lastly light the Christ candle and then pray.

Make it a treasure hunt
When my kids were little, I hid each piece of the Nativity and they went on a "hunt" to find each piece to complete the scene. They loved it! They were also learning what was part of the Nativity as they hunted for the shepherds, baby Jesus, etc...
Advent breakfast
We light the candles around the Advent wreath while eating breakfast together. We use some form of the booklet that Gateway has given out over the years for the readings. We've expanded the readings as our kids have gotten older. We end the time together in prayer.
A star is born
When our children were very little we had a child-friendly nativity scene. We would read the Christmas story from a children's Bible and let the kids hold or "act out" the story with the figures (depending on their age) while we read the story. As they got older they could tell the story and place the figures in the scene themselves. Kind of like a children's puppet show
