How often should you change up your bottles and nipples?

Every feeding: Bottles and nipples should be washed in hot soapy water and dipped in boiling water or use dishwasher after each use. After you open and use a bottle to feed, finish the feed within 1 hour and then wash the bottle and nipple before the next use. Reuse of bottles and nipples can lead to thrush, a yeast infection, of the infants lips, tongue and insides of cheeks causing white thick patches.

Last a long time: Baby bottles last a long time. They don't need to be recycled unless they are looking very old or are showing some surface cracks. Nipples can be thrown away (probably not recyclable) if they have lost the soft, smooth, flexible texture. Just keep bottles and nipples very clean, and they should last a long time.

As your baby grows: Newborns generally are most comfortable with a slow flow nipple, but as they get older a faster flow nipple may be better. You can keep using the same bottles, as long as there are no cracks in them. Wash with hot soapy water after each use and sterilize at least once a week if using regularly.
