All of my kids between 5 and 13 especially loved these yogurt parfaits, and were able to make them themselves with very minimal help from mom (mostly clean-up!).
Spoon 1/2 cup yogurt into a small dessert dish.
Layer with 1/2 cup berries.
Layer with 1/4 cup granola.
Stir to combine. Repeat in separate dish and serve.
