A drinking/feeding container and method for delivering fluid to a user at a drinking/feeding temperature which is higher than a storage temperature of the fluid. The container includes a fluid storage compartment, a lid and a heating device. The heating device is positioned between the fluid storage compartment and the lid. The heating device has an inlet which accepts the fluid from the fluid storage compartment, an outlet which dispenses the fluid to the lid and a passageway which extends between the inlet and the outlet. A Peltier device is provided between the inlet and the outlet and cooperates with the passageway to heat the fluid as the fluid moves from the inlet to the outlet. A power source supplies power to the heating device. A pulsing member pulses the power to the heating device whereby the pulsing of the power prevents the heating element from overheating.
