The anti-colic internal vent system features an enhanced design to improve an already innovative feeding experience:

• Clinically proven to reduce colic
• Decreases spit-up, burping, and gas
• Shown to better preserve nutrients in breast milk and formula
• Aids in digestion for a good nights sleep
• Offers a flow rate that supports breastfeeding.

Its Good to Have Options+

Our bottles work best with the vent system in place but its great to have options when babys feeding develops. Just remove the vent when you feel its time no need to introduce a different bottle. With the vent system removed, the feeding experience is similar to most nipple-vented bottles.
