Whether using formula or breast milk, preparing your baby's drink is simple and fast with the Cuisinart Baby® Bottle Warmer. The warming chamber safely steam heats small or large glass or plastic bottles to the right temperature every time. Simply insert your bottle following the instructions and then turn the dial to on. The blue light will come on and automatically turn off once the bottle or food has been brought to temperature. The unit also includes a basket to warm baby food jars, and a soothing night-light feature to make those midnight feedings a little easier.
