First Baby Food: Peas

3 cups frozen peas

½ cup breast milk

Place a steamer insert into a saucepan and fill with water to just below the bottom of the steamer. Bring water to a boil. Add peas, cover, and steam until tender, about 15 minutes.

Place peas and breast milk in a blender or food processor and puree until creamy. Strain the mixture through a fine-mesh sieve to remove any lumps.

Spread pea mixture into an ice cube tray, cover with plastic wrap and freeze until solid, 2 to 3 hours. Transfer frozen cubes to a resealable plastic bag and store in the freezer.

To serve, heat cubes in the microwave for about 30 seconds until warm but not hot. Stir thoroughly.
