1. Start by rinsing the blueberries under cool, running water to ensure they are clean.
2. Place the washed blueberries in a medium saucepan and add about 50 ml of water to help with steaming.
3. Cover the saucepan with a lid and cook over low heat for about 5-7 minutes, allowing the blueberries to soften and release their juices.
4. Once softened, remove the saucepan from heat and let it cool for a few minutes.
5. Transfer the cooked blueberries (and any liquid) to a blender or food processor.
6. Blend the mixture until smooth, adding a little more water if necessary to reach your desired consistency.
7. If you prefer a finer texture, you can strain the puree through a fine mesh sieve to remove any seeds.
8. Allow the puree to cool completely before serving to your baby.
