Put about 2 inches of water in a small pot and bring it to a soft boil. Add the steamer basket to the pot.
Wash the pears and cut them into quarters. (Peeling the pears is optional.)
Add the pears to the steamer basket and cover the pot. Steam the pears for 10-20 minutes, or until the pears are completely soft.
Add the pears to a blender and blend until smooth. Add water, formula or breast milk as needed, until you reach your desired consistency.
