There are many ways to make fun lunch for kids. One way is to make a themed lunch. For example, you could make a zoo lunch with animal crackers, a fruit salad in the shape of a monkey, and a juice box in the shape of a lion. You could also make a lunch with a fun activity. For example, you could put a small box of crayons and a piece of paper in the lunch box and let the child color on the paper. You could also put a small puzzle in the lunch box. Another way to make a fun lunch is to include a treat. For example, you could include a small bag of chips or a candy bar.
