Make sure your rice baby cereal is fully cooked. Cut the ripe mango into small pieces, or thaw frozen mango safely in the refrigerator.
Add 1/2 cup cooked rice baby cereal, 1/4 cup mango, 1/8 cup unsweetened canned coconut milk, and the optional 1/8 teaspoon grated ginger to a blender or food processor.
Blend until the cereal reaches your desired consistency. Add a little water if needed. You can also use prepared infant formula or breast milk once the ingredients have cooled.For babies ready for thicker textures, blend less thoroughly, making sure the mixture remains soft and age-appropriate. Check the temperature and texture before serving. Serve immediately or refrigerate promptly for later.
