This compact sterilizer, which holds four bottles, nipples, and caps, works in your microwave yet provides the same hot steam cleaning as electric models. All you need to do is fill the sterilizer with 200 ml. of water, load it with your feeding supplies, and put it in the microwave on high for about four minutes. Allow the unit to cool for two to three full minutes before unloading; it will emit hot steam as it cools. The unit is about the size of a large mixing or salad bowl and can be used to clean anything made from microwave-safe plastic, from toddler cups to pacifiers. It also holds Avent's ISIS breast pump with accessories.
