Place the oats, milk and water in the slow cooker.

Add the blueberries to the slow cooker and stir.
Cook on high for 2 hours or on low for 4-5 hours. If cooking overnight you can use a timer.
Heat the rest of the blueberries as before and stir them through before serving for swirls of colours.
To serve, add a handful of blueberries, and if you wish a drizzle of honey and a few sunflower seeds.
