The Dr. Brown’s Natural Flow 4oz. Wide-Neck Bottles are designed to provide a feeding experience that promotes good health and closely mimics breastfeeding. Dr. Brown’s bottles have a patented internal vent system that prevents vacuum, negative pressure and air bubbles inside the bottle to reduce common bottle feeding problems.

Health Benefits

• 
  
   Breastmilk and air in the bottle are kept separate which allows baby to control milk flow and eat at his own pace.


• 
  
  Reduces the likelihood of common feeding problems such as spit-up, burping, gas and colic.


• 
  
  The lack of negative pressure in the bottle decreases the risk of fluid building up in baby’s ears.


• 
  
  Each bottle has ounce and milliliter graduation marks for easy measuring and is top rack dishwasher safe.

Dr. Brown’s 4oz. Wide-Neck Bottle 3-Pack comes complete with three 4oz. wide-neck bottles, a cleaning brush and instruction sheet. Each bottle includes the two-piece patented internal vent and a Level-One silicone nipple.
