A system and method are provided for warming a nutritional substance (i.e. mothers milk or formulated liquids) for ingestion by a neonate. Structurally, the system includes a warmer for holding a container of the nutritional substance as it is simultaneously vibrated and warmed in preparation for the neonate, and it includes a controller which determines how the system will be operated. For an operation of the present invention, a user provides input to the system controller to establish a mode of operation (e.g. warming warming-frozen or thawing). The user will also input a predetermined protocol to the controller. During the operation, a heat sensor monitors temperatures of the nutritional substance which are provided as feedback input to the controller for operating the warmer in accordance with the protocol.
