1. Start by washing the zucchini thoroughly under running water to remove any dirt or residues.
2. Trim the ends of the zucchini and cut it into small chunks for easier cooking.
3. Place the zucchini chunks in a steaming basket over boiling water. Cover with a lid and steam for about 10-15 minutes, or until the zucchini is tender and easily pierced with a fork.
4. Once the zucchini is cooked, remove it from the steaming basket and let it cool slightly.
5. Transfer the steamed zucchini to a blender or food processor. Blend until smooth, adding a little water if necessary to achieve a desired consistency. It should be thin enough for a baby to swallow easily.
6. Allow the puree to cool completely before serving it to your baby.
