3. Prepare your bottle

Sterilize bottles, nipples, caps and rings before using them for the first time. You can boil the bottle and accessories in water for five minutes, use a microwave steam sterilizer bag or use a stand-alone electric steam sterilizer.

After the first use, there's usually no need to sterilize your bottle and accessories. Wash these items with soap and hot water. Bottle and nipple brushes can help you clean nooks and crannies. You can also use a dishwasher.

However, if your baby is younger than 3 months, was born prematurely or has a compromised immune system, you might consider continuing to sanitize feeding items.
