An example milk storage system and associated methods are described. The example milk storage system includes a milk storage bag with a body forming an inner chamber for receiving milk. The milk storage bag includes a first closure mechanism extending across the body and separating the body into a bottom section and a top section. The milk storage bag includes a preperforated section formed in both the first and second side walls of the top section of the body and spaced from edges of the top section. The preperforated section is removable from the top section of the body to form an opening extending through the top section. The milk storage system includes a hanging apparatus including a mounting section and an extension protruding from the mounting section. The extension passes through the opening in the milk storage bag to support the milk storage bag in a hanging orientation.
