1. An insert and feeding bottle system, comprising:
a bottle forming a reservoir chamber comprising walls having a first segment and a second segment, a bottom surface and an upper opening substantially parallel to the bottom surface, whereby the first segment of the reservoir chamber walls comprises pliant material and is substantially circular in cross-section, and the second segment of the reservoir chamber wall comprises non-pliant material and is substantially circular in cross-section;
a nipple disposed above the reservoir chamber, the nipple comprising a dispensing chamber;
a circular plate sized and shaped to be mounted over the opening of the reservoir chamber between the reservoir chamber and the nipple, the circular plate configured to separate the reservoir chamber and the dispensing chamber;
a one-way valve disposed on the circular plate for allowing the passage of fluid from the reservoir chamber in response to negative pressure;
whereby the pliant material is configured to be deflected a sufficient distance to directly contact fluid that is in direct contact with the pliant material to force fluid through the one-way valve and cause the one-way valve to temporarily fail and cause the flow of fluid from the reservoir chamber to the dispensing chamber in the absence of negative pressure, whereby the reservoir chamber is configured to store fluid in the absence of negative pressure.
