What weabout it
This bottle’s unique venting system eliminates air bubbles during feeding and maintains nutrients.

About this Product
  • Venting system eliminates air intake
  • Preserves key nutrients
  • Traditional narrow shape
  • Self-paced flow


Tiny tummies can be super sensitive. When your little one isn’t feeling well, you’ll do anything to make it better. One major trick? Reducing air intake during feeding. Dr. Brown’s bottles were developed with this in mind. The two-part internal vent system keeps air separate from the liquid, moving it to the very bottom of the bottle. Because air contact with milk or formula is minimal, nutrients like Vitamins A, C, and E, that degrade when exposed to oxygen, remain intact.

While parents swear by the power of Dr. Brown’s bottles to reduce burping, spit-up, and even colic, cleaning the vent parts requires a special brush. (You could also wash them in a basket in the top rack of your dishwasher.) Also, correctly putting everything back together so it doesn’t leak takes practice.

These bottles are also available in a glass version, and the nipples and vent parts are compatible between the glass and plastic ones.
