1. A method of nursing comprising:filling a bottle liner with milk, said bottle liner comprising a container comprising a flexible bag forming a tube with a generally flat bottom end and an open top end and a circular flange extending about the open end of the bag along an upper portion thereof and defining a fixed opening at the open end of the bag, the container having an inner surface extending from the bottom end of the bag and including a surface of the flange defining the fixed opening, and a lid comprising a wall projecting from a bottom surface thereof and configured to fit within the opening and a sealing ring having a diameter larger than the diameter of the opening and extending radially outward from the wall, the sealing ring being configured to fit within the fixed opening of the flange and form a fluid-tight seal with the inner surface of the container; inserting the container into a nursing device; opening the lid to expose the milk; and securing a nursing nipple to the nursing device with the container disposed therein. 2. The method of claim 1, wherein the lid is integrally attached to the flange.3. The method of claim 2 further comprising removing the lid from the container.4. The method of claim 1 further comprising storing the milk in the flexible container for a period of time in between filling the container and opening the lid.5. The method of claim 1 further comprising freezing the milk.6. The method of claim 1, wherein filling comprises inserting an empty container into a breast pump and extracting milk from a breast into the container.7. The method of claim 1, wherein the flange comprises an upper surface, a sealing lip disposed on the upper surface configured to form a fluid seal with the nursing nipple, and a ring projecting inwardly from the inner surface to define the fixed opening.8. A nursing bottle comprising:a nursing nipple; a liner comprising: a container comprising: a flexible bag forming a tube with a generally flat bottom end and an open top end; a circular flange extending about the open end of the bag along an upper portion thereof and defining a fixed opening at the open end of the bag; an inner surface extending from the bottom end of the bag including a surface of the flange defining the fixed opening; a lid comprising a wall projection film a bottom surface and configured to fit within the fixed opening and a sealing ring having a diameter larger than a diameter of the opening and extending radially outward from the wall, the sealing ring being configured to fit within the fixed opening of the flange and form a fluid-tight seal with the inner surface of the container; a rigid holder disposed about the liner and having a shoulder supporting the lower surface of the flange; and a removable collar attached to the holder to secure the flange and the nipple and permitting fluid communication between the liner and the nipple. 9. The nursing bottle of claim 8, wherein the flange comprises an upper surface and a sealing lip disposed on the upper surface configured to form a fluid seal with the nursing nipple.10. A disposable drop-in bottle liner sized to fit within a baby bottle, the liner comprising:a container comprising: a flexible bag forming a tube with a generally flat bottom end and an open top end; a circular flange extending about the open end of the bag along an upper portion thereof and defining a fixed opening at the open end of the bag; an inner surface extending from the bottom end of the bag and including a surface of the flange defining the fixed opening; and a lid comprising a wall projecting from a bottom surface thereof and configured to fit within the opening and a sealing ring extending radially outward, the sealing ring being configured to fit within the fixed opening of the flange and form a fluid-tight seal with the inner surface of the container. 11. The bottle liner of claim 10 wherein the lid comprises a lower surface and the sealing ring is spaced apart from the lower surface, such that the fluid-tight seal between the sealing ring and the inner surface is substantially formed at a position at which the bag has a thickness of about 0.00275 inches.12. The bottle liner of claim 10 wherein the flange further comprises a ring projecting inwardly from the inner surface to define the fixed opening.13. The bottle liner of claim 10 wherein the flange further comprises a sealing ridge disposed on and projecting from an upper surface of the flange and configured to flange fluid-tight seal with a nipple.14. The bottle liner of claim 10 wherein the lid is integrally connected to the flange by a living hinge.15. The bottle liner of claim 10 wherein the lid is integrally connected to the flange by a tether.16.
