Abstract: The portable infant bottle filler and warmer machine may make it much easier to prepare bottles of formula or breast milk when feeding babies. It may be used at home, in a hospital, and while traveling. The machine mixes the appropriate amount of formula and water based on the ounces needed for the baby, and once mixed, warms the liquid to the appropriate temperature for feeding. The machine may also be used to pump and manage breast milk production. Pumped breast milk is kept cool until ready for use, and is then warmed to the necessary temperature. Other items such as wipes may be warmed within the machine as well for the comfort of the baby.
