Abstract A device for improving dispensing of fluid from a nursing bottle that maintains the proper pressure to prevent an infant, while using the nursing bottle, from receiving air. The device is used with a conventional nursing bottle employing a flexible bag within the bottle structure and operates to provide a force against the bag to insure that no air is received in the bag, insuring that the infant, while feeding, receives no air. Specifically, the device includes a pneumatic biasing member which is inserted by an attached handle into the base opening of the nursing bottle and is placed in communication with the flexible bag containing the baby's formula. The pneumatic biasing member is pressed against the flexible bag to effectively regulate the proper fluid pressure within the bag such that an infant may feed from the nursing bottle without receiving air, with or without attendant supervision.
