We used it for 6 months with our twins. I recommend Dr. Brown's bottles to cut down on the gas and we made several bottles in advance so the bubbles would settle. We stored them in the refrigerator and heated them in a pan of water on the stove. We could never just shake and serve, too much gas... They are using Similac Advance now and we still keep us the same routine.
