  "answer": "Haakaa Generation 2 100/150ml Silicone Breast Pump with Suction Base: All Haakaa pumps share the same flange size and are one-size-fits-all because the flange is soft flexible silicone. The listing labels each pump's size as 4 oz (100 ml). Haakaa Generation 3 Silicone Breast Pump: All Haakaa pumps have the same size flange. The Gen 3 pump comes in 160ml/6oz and 250ml/9oz capacities. Haakaa Generation 2 Silicone Breast Pump with Suction Base 5 oz (150 ml): The flexible silicone flange moulds to the breast and accommodates different breast sizes.",
