Feeding container venting apparatus and methods are disclosed. A vent structure is mounted through an opening formed in a feeding container adjacent to its fill port and includes a pliable protrusion extending from an inner diameter of an annular rim. The protrusion has a hollow interior, a ported end at the rim and a distal end having a slit thereat allowing communication with the hollow interior. The pliable protrusion is pressed through the container opening to reside interior of the container adjacent to the container fill port with the rim abutting the exterior of the container. A spacer is located at the rim with a portion spaced axially from the inner diameter of the rim to prevent inadvertent blockage of air flow to the hollow interior of the protrusion, and a membrane extends partially across the inner diameter of the rim to inhibit fluid leakage from the hollow interior of the protrusion. A cutting tool for retrofitting feeding containers is also disclosed.
