1. Place water, potato, onion, carrot, lentils and pumpkin in a small saucepan over high heat; bring to the boil; simmer until potato and lentils are tender, about 10-15 minutes.
2. Puree in a food processor or blender until smooth, adding more boiled water if necessary to achieve the required consistency. For older babies, simply mash with a fork.
TIP: The recipe can be doubled and extra servings can be placed in airtight containers and frozen for later use.
