Place the pumpkin in a casserole dish with an inch of water.
Bake for 45 minutes, or until it's soft when you press an oven mitt-covered hand against the side.
Allow the pumpkin to cool for 30 minutes.
Cut the pumpkin in half and scoop the flesh out, placing it in a mixing bowl or directly into a blender or food processor. You want to avoid the skin and any remaining seeds.
Peel the banana, and break off pieces to add to the pumpkin. Sprinkle with a dash of cinnamon, if desired.
Process, blend, or mash the ingredients until the food is the desired consistency (pureed for babies just starting on solids, and chunky for more experienced babies).
Freeze leftovers in cubes.
