In a medium saucepan, bring 2 inches of water to a boil. In a steamer basket, place the chopped carrots and pumpkin, cover and steam for 7 minutes. Add in the corn on top of the carrots and pumpkin, cover and steam for an additional 3 minutes.
Let cool. Reserve the steamer water.
Transfer all of the ingredients into a blender and puree on high for 1-2 minutes or until completely smooth. If puree is too thick, add in reserved steamer water, breast milk, formula, chicken broth or water in 1/4 cup increments until you reach your desired consistency. I added in 1/2 cup of reserved water to the puree pictured above.
Serve and enjoy!
