Please keep the following in mind: Use 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 Avoid formula bubbles: Do not shake the bottle. Formula should be stirred gently to fully dissolve lumps - they can clog nipple holes. Fill to the desired a. The vent will not work properly if you fill the bottle above the FILL LINE WARNING. Snap the reservoir fully onto the insert. Place the reservoir into the bottle, with the insert making full contact with the top of the bottle. Snap the nipple into the nipple 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 forms during warming. Do not warm the liquid beyond body temperature of 98.6°F (37°C). Always test temperature of liquid before feeding baby. Be sure to tighten the collar snugly before feeding, but do not over-tighten. When you use formula, make it up strictly according to the manufacturer's instructions. Reminders 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. 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) Keep your baby propped up rather than lying down during feeding. While the vent continuously equalizes pressure, movement of any liquid remaining in the reservoir tube is normal. 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) When transporting bottles, always keep them upright and use travel disk to help prevent leaking. During air travel, please remove internal parts and secure with travel cap or travel disk and nipple collar to prevent leaking from air pressure For proper bottle and venting functions, use only Dr. Brown's Natural Flow nipples. Keep nipples out of direct sunlight when not in use. Sunlight is known to cause deterioration o

• Dr. Brown's - Natural Flow Wide-Neck Baby Bottle 2 Pack - 4 oz. (4 oz. / 120 mL each) Dr. Brown's Natural Flow Wide Neck Baby Bottles feature an ergonomic design that's easy to fill and hold. The silicone nipple has a broader base which some feeding moms prefer. How They Work: Bottles Dr. Brown's bottle features a patented two-piece internal vent system that works unlike any other bottle design. The vent system fully vents their bottle for vacuum-free feeding, which they call positive-pressure flow, similar to feeding. As the baby feeds, air is channeled from the nipple collar through the vent system, bypassing the milk or formula, to the back of the bottle. Air never mixes with the milk or formula which minimizes oxidation and helps preserve essential ents like s C, A and E. Babies feed more comfortably because the vent system allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce feeding problems like colic, spit-up, burping, and . The milk or formula flows freely, without nipple collapse. Dr. Brown's ent Study New Study Reveals Loss of s A, C, & E in Some Baby Bottles During 20-Minute Simulated Feeding A newly released study revealed that after a 20-minute bottle feeding, three important ents for infants–s A, C and E–all declined during the course of feedings. The results suggest that the a of air within a baby bottle, the bottle's design, and the impact on levels warrant closer examination. How The Study Was Conducted The study, "Comparative Analysis of Retinol, Ascorbic , and Alpha-Tocopherol in Baby Milk Using Varied Delivery Systems," was conducted at the University of Nevada-Reno. The bottle study was designed to investigate changes in ent levels that might occur during a typical bottle feeding time of 20 minutes, using both expressed human milk and infant formula, in both vented bottles and unvented bottles. The study looked at the a of ents in the milk when delivered through seven commonly used baby bottles, including Dr. Brown's. The purpose was to determine if exposure to air within a baby bottle during a simulated feeding affected ent levels. Dr. Brown's Bottles Preserve ents When Others Don't The graph demonstrates the loss of C during a 20-minute simulated feeding. While C began to decline at 5 minutes as shown by this graph, s A and E declined later. C prevents oxidation of ents and, as it is lost, other ents are more susceptible to damage. The Food and tion Board at the Institute of Medicine recommends a C intake of 40 mg per day, 3 mg of E and 400 mcg of A for infants up to six months old. The Importance Of ents For Babies All three s studied are important in infant and growth. Medical research shows that children with low intakes of C are more vulnerable to developing frequent and more severe common day-to-day illnesses. Inadequate intake of E can lead to anemia and degeneration of the spine and brain. In infants, a low intake of A disrupts growth and interferes with the development of immature cells resulting in weak, poorly formed s. A is also needed to produce immune cells that are associated with increased resistance to infection. Why Dr. Brown's Bottles Preserve ent Levels The ability to preserve ents in bottle feeding appears to be influenced by bottle design. Once C–which is known to be susceptible to oxidation– degrades to a certain point, s A and E begin to decline as well. The bottles used in the study were different from each other in the way that air is replaced in the bottle as milk is removed. Only one bottle–Dr. Brown's–had a vent system that allows air moving into the bottle to bypass movement through the milk, with no bubbles forming as milk is r.
