Fasting is one of the pillars of Lent. This is a family activity to determine what to fast from each day.
Pick 10 things that everyone in the family is able to fast from. Write each on a small piece of paper and place it in a cup. Consider putting the cup on a family prayer table.
Each morning during Lent, each person in the family picks one of the slips of paper from the cup. That is what they will be fasting from that day. So each person will be fasting from something different.
At the end of the day, put the slip of paper back in the cup, so it can be used again the next day.
Family members can choose to tell each other what they are fasting from or they can keep that to themselves.
Alternately, you can choose one item for the whole family each day. Everyone will fast from that.
