The First Years' popular bottle warmer works with all bottle styles -- standard, wide-necked, angled, even disposables. You can also use it to warm jars of baby food. It keeps bottles cold for up to eight hours, then warms a chilled bottle in minutes. Features an auto shut-off for added safety and a built-in night light that helps makes late-night feedings a little easier. Bottles not included. About the size of a coffee maker, this electric baby bottle warmer will be a big convenience for bleary-eyed parents who are tired of stumbling down to the kitchen in the middle of the night. At the rear of the unit, an insulated compartment keeps two 8-ounce bottles cool for up to eight hours. (There's no refrigerant, just a specially shaped container that can be filled with water, frozen, and then slipped into place.) At the front, an electrically heated water container produces steam, which heats one bottle to the correct temperature in about five minutes. There's also a night-light built into the front of the unit.
