Sterilizing Bottles and Nipples You can sterilize bottle-feeding equipment by boiling, soaking in chemical solution or using an electric or microwave sterilizer. Please keep the following in mind:

  • Use chemical solutions or sterilizers strictly according to the manufacturer's instructions. They advise you to use the Dr. Brown's Microwave Sterilizer.
  • Steam can cause severe skin burns, so be careful when boiling equipment on the stove or using sterilizing equipment.
  • Keep all components not in use out of reach of children.
  • Wash your hands thoroughly with soap and water before handling sterilized bottles, nipples and accessories.
  • Avoid unnecessary handling of sterilized equipment.

Assembly and Feeding Instructions Note: The bottle WILL NOT FUNCTION without the INSERT and RESERVOIR

  1. Avoid formula bubbles: Do not shake the bottle. Formula should be stirred gently to fully dissolve lumps - they can clog nipple holes.
  2. Fill to the desired amount. The vent will not work properly if you fill the bottle above the FILL LINE WARNING.
  3. Snap the reservoir fully onto the insert.
  4. Place the reservoir into the bottle, with the insert making full contact with the top of the bottle.
  5. Snap the nipple into the nipple collar and place loosely on the bottle.
  6. Warm the bottle - always remove all bottle components before warming to prevent the vent from leaking fluid if gas forms during warming.
  7. Do not warm the liquid beyond body temperature of 98.6°F (37°C). Always test temperature of liquid before feeding baby.
  8. Be sure to tighten the collar snugly before feeding, but do not over-tighten.
  9. When you use formula, make it up strictly according to the manufacturer's instructions.


  1. The nipple included has been specifically selected for an infant's first use of the free-flowing characteristics of the Dr. Brown's Natural Flow venting system. Faster flowing Level 2, Level 3, Level 4 and Y-Cut versions of the nipple are available for all Dr. Brown's baby bottles. There is also a slower flow Preemie nipple available for the standard bottle only. Nipples of other brands may leak or feed too fast or too slow.
  2. When feeding your baby, hold the bottle so that the reservoir tube hole in the bottom of the bottle is not covered by liquid. (Approximately at a 45° angle)
  3. Keep your baby propped up rather than lying down during feeding.
  4. While the vent continuously equalizes pressure, movement of any liquid remaining in the reservoir tube is normal.
  5. If the reservoir bulb remains over 1/3 full when the bottle is placed upright, please check that the nipple hole is clear and that the insert and reservoir are firmly pressed together. The reservoir bulb can be emptied by momentarily loosening the nipple collar. (Be sure to retighten before feeding)
  6. When transporting bottles, always keep them upright and use travel disk to help prevent leaking.
  7. During air travel, please remove internal parts and secure with travel cap or travel disk and nipple collar to prevent leaking from air pressure
  8. For proper bottle and venting functions, use only Dr. Brown's Natural Flow nipples.
  9. Keep nipples out of direct sunlight when not in use. Sunlight is known to cause deterioration of nipples.
  10. Change nipples after approximately 6 weeks of use. When used and sterilized intensively, nipples may deteriorate after 6 weeks.

All Dr. Brown's bottles, nipples and bottle accessories are tested according to EN14350; the baby bottle feeding standard for Europe.

  • Instructions


Do not use a microwave oven to heat the bottle because microwave ovens can create hot spots in milk or formula. Test the nipple by pulling on the bulb portion, and replace if nipple shows any signs of wear. Wash all parts prior to use. Do not let a child take a bottle to bed or self-feed for long periods. Allowing your child to use this product for prolonged periods separate from regular mealtimes or to go to sleep while drinking liquids, other than water, from this baby bottle may cause or contribute to early childhood tooth decay. Always test temperature of liquid before feeding baby.


  1. Due to the risk of creating formula hot spots and overheating, the use of a microwave oven is not recommended. If you use a microwave oven, remember that the nipple and collar must always be removed during heating. Test temperature frequently by placing a few drops on your tongue or back of your hand after stirring thoroughly to eliminate hot and cold spots.
  2. Pull on the nipple before each use to make sure it does not tear. Inspect carefully, especially when the child develops teeth, and replace the nipple immediately if it shows any signs of wear or damage, such as cracking or change of shape.
  3. Stop feeding before your baby has completely emptied the nipple to keep your baby from swallowing air that may cause colic or other digestive problems.
  4. Remove the bottle from your baby's mouth when the baby is not feeding. Prolonged contact with milk, formula, and other liquids can cause tooth decay.
  5. The components of this bottle are not toys and should not be given to children to play with or suck on.
  6. Be sure to contact your physician should you have any feeding problems or questions.
  7. Allowing your child to use this product for prolonged periods separate from regular mealtimes or to go to sleep while drinking liquids, other than water, from this baby bottle may cause or contribute to early childhood tooth decay.
