A rotatable connector for a breastmilk system. The connector can be customized to provide a range of rotatable motion based on a selected size, shape and material. The connector can be designed to allow a wide range of motion, as needed, during use. The connector can be located near or at least partially within a connecting component of the system, as desired. Some, or all, of the material of the connector can be designed to rotate in response to forces applied to the connector during use.
