1. Cook the rice according to the package instructions. This generally involves rinsing the rice and boiling it with water until it is soft and fully cooked. Allow the rice to cool slightly.
2. In a blender or food processor, add the cooked rice and oat milk. Blend until you achieve a smooth, pudding-like consistency.
3. Peel the ripe banana and add it to the blender. Blend again until the banana is fully incorporated into the mixture and it becomes a smooth puree.
4. Add 1 teaspoon of maple syrup to the mixture and blend briefly to combine.
5. Once the puree is smooth and well-mixed, transfer it to a serving bowl.
6. Allow the puree to cool to a safe temperature before feeding it to your baby.
