Standard Dr. Brown's Natural Flow, vented, baby bottle with Level-One nipple.
Preemie flow nipples (pacakge of three) are also available.
The Dr. Brown’s Natural Flow baby bottle is the only baby bottle that features a patented internal vent system.
This vent eliminates the air bubbles and vacuum effect to allow positive-pressure feeding with no air – similar to breast-feeding.
The innovative design of the Dr. Brown’s Natural Flow offers these advantages over other baby bottles:
- Reduces colic, spit-up, burping, and gas
- Prevents air bubbles from forming in milk or formula
- Helps reduce fluid in the ear
- Prevents nipple collapse
