Abstract: An infant nursing device has flexible side walls which may be compressed to cause pressure on the removable internal fluid containing bag causes air to be expelled out of the unidirectional tip opening of a nipple located atop the device. The infant nursing device is assembled by securing a top assembly to the top portion of the device. The top assembly holds the removable bag and nipple assembly in place. The infant nursing device does not include any mechanical parts that may get caught on the baby, clothes, and surrounding things, while providing an easy method and device for removing air from a baby's nursing food.
