Our Sunday school class, called the "Young Marrieds" class, had a family party where we all brought our kids and played games. There were toilet seat races using plungers and seats with wheels on them. Even some of the adults raced! It was tough when they paired up two of my kids at a time because I didn't know who to cheer for.
There was also a cake walk at the end. We brought several desserts since we had 8 kids participating. All of our kids won something and were very happy.
