Dr. Brown’s Natural Flow Options Bottle
GLASS WARNING
Glass bottles may break. Bottles should be inspected before each use
for sharp edges and fragments or flakes of glass that may have become dislodged and are loose inside the bottle. Do not use bottles if there are any cracks or chips on the bottle. Sudden temperature changes can cause glass bottles to crack or break. Be sure the bottle and liquid are the same temperature when filling or warming.
Do not use a microwave oven to heat the bottle because microwave ovens can create hotspots in milk or formula. Always test the temperature of the liquid before feeding baby.
This bottle may only be used with adult supervision. Do not let child feed themselves with glass. Do not let the child walk with glass. Do not let a child take a bottle to bed.
Before first use, sterilize the bottle, nipple/teat, and parts by leaving them in boiling water for five (5) minutes. After every use, the bottle, nipple/teat, and parts should be washed thoroughly with hot, soapy water.
CLEANING
Wash all parts prior to use. The cleaning of the two (2) additional vent assembly parts will require an extra moment. This is time well spent to help avoid spit-ups and other discomforts to your baby.
Be sure to remove wire cleaning brush from the bottle before cleaning.
- Always use clean hands and surfaces.
- Fully disassemble all parts.
- Silicone nipple/teat – first use only: boil the nipple/teat in water for five (5) minutes.
- Wash all parts thoroughly in hot water and detergent. Use the enclosed brush on all holes in the insert and reservoir.
- Rinse parts thoroughly, making sure that the nipple/teat hole is clean and clear.
- I f you use a dishwasher, keep all parts in the top rack only.

STERILIZING BOTTLES AND NIPPLES/TEATS
You can sterilize bottle-feeding equipment by boiling it, soaking in a 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. We advise you to use the Dr. Brown’s® Microwave or Electric Sterilizer.
- Steam can cause severe skin burns, so be careful when boiling on the stove or using any 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/teats, components and accessories.
- Avoid unnecessary handling of sterilized items and equipment.
- Do not sterilize wire cleaning brush. Be sure to remove this from bottle before cleaning.
For Your Child’s Safety and Health
WARNING!
- Always use this product with adult supervision.
- Never use feeding nipples/teats as a pacifier/soother.
- Continuous and prolonged sucking of fluids will cause tooth decay.
- Always check food temperature before feeding.
- Always check the nipples/teats for signs of wear and replace them when damaged.
ASSEMBLY and FEEDING INSTRUCTIONS
(Please refer to diagram)
FOR FULLY-VENTED (VENT INSTALLED) BOTTLE FEEDING
- Avoid formula bubbles: Do not shake the bottle. The formula should be stirred gently to fully dissolve lumps – they can clog nipple/teat holes.
- Fill to the desired amount. The vent will not work properly if you fill the bottle above the FILL LINE WARNING.
- Snap the insert fully onto the reservoir.
- Place the reservoir into the bottle, pressing the insert into the bottle with the insert making full contact with the top of the bottle.
- Snap the nipple/teat into the nipple/teat collar and place loosely on the bottle.
- Warm the bottle – always remove all bottle components before warming to prevent the vent from leaking fluid if gas forms during warming.
- Do not warm the liquid beyond the body temperature of 98.6°F (37°C). Always test the temperature of liquid before feeding baby.
- Be sure to tighten the collar snugly before feeding, but do not over-tighten.
- When you use a formula, make it up strictly according to the manufacturer’s instructions.
FOR NIPPLE/TEAT-VENTED (VENT REMOVED) BOTTLE FEEDING While it is always recommended that the vent system be installed for the best feeding for your baby, this bottle will function as a conventional bottle without the vent system installed.
Simply remove the vent assembly. Some moms and dads find this a good option as their baby’s feeding becomes more developed or if their baby no longer has symptoms of colic.
CAUTIONS
- 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/teat 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.
- Pull on the nipple/teat before each use to make sure it does not tear. Inspect carefully, especially when the child develops teeth, and replace the nipple/teat immediately if it shows any signs of wear or damage, such as cracking or change of shape.
- Stop feeding before your baby has completely emptied the nipple/teat to keep your baby from swallowing air that may cause colic or other digestive problems.
- 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.
- The components of this bottle are not toys and should not be given to children to play with or suck on.
- Be sure to contact your physician should you have any feeding problems or questions.
- 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.
REMINDERS
- A. The nipple/teat 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/teat are available for all Dr. Brown’s® baby bottles. There is also a Preemie Flow™ nipple/teat available for a slower flow than the Level 1 nipple/teat. Nipples/teats of other brands may leak or feed too fast or too slow.
- B. 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.)
- C. Keep your baby propped up rather than lying down during feeding.
- D. While the vent continuously equalizes pressure, movement of any liquid remaining in the reservoir tube is normal.
- E. I f the reservoir bulb remains over 1/3 full when the bottle is placed upright, please check that the nipple/teat hole is clear and that the insert and reservoir are firmly pressed together. The reservoir bulb can be emptied by momentarily loosening the nipple/teat collar. (Be sure to retighten before feeding.)
- F. When transporting bottles, always keep them upright and use travel cap to help prevent leaking.
- G. During air travel, please remove internal parts and secure with a travel cap to prevent leaking from air pressure.
- H. For proper bottle and venting functions, use only Dr. Brown’s Natural Flow® nipples/teats.
- I. Do not leave feeding nipples/teats in direct sunlight or heat or leave in disinfectant (sterilizing solution) for longer than recommended, as this may weaken the nipple/teat.
- J. Change nipples/teats after approximately 6 weeks of use. When used and sterilized intensively, nipples/teats may deteriorate after 6 weeks. All Dr. Brown’s® bottles, nipples/teats and bottle accessories are tested according to EN14350; the baby bottle feeding standard for Europe.
