The technology herein includes embodiments of a flip-up potty seat comprising a ring connected to a mount via a hinge, wherein the ring can be positioned on a toilet seat of a regular, adult-sized toilet and the mount can be attached to a toilet lid of the regular, adult-sized toilet. Utilizing the technology disclosed herein, improved and sanitary methods of potty training are provided that enable convenient use of a typical standard, adult-sized toilet in a household with convenient, sanitary and immediate inter-conversion of the standard toilet to accommodate adults, children and toddlers, thus saving the need to purchase (and thereafter empty), expensive, limited use and cumbersome potties (e.g., potty chairs) solely devoted to the task of potty training.
