Dr Brown's Options+ bottles feature the new breast-like nipples that encourage proper latch for a more natural feeding experience. Designed alongside medical professionals, the correctly contoured nipple shape and high-grade soft silicone offer comfortable feeding and help to avoid nipple confusion. The fully-vented bottles are clinically proven to reduce colic, better preserves nutrients, aids in digestion for a good night's sleep, and provide a flow rate that supports breastfeeding. Options+ bottles work best with the vent system in place, while parents can choose to remove the vent when baby's feeding develops.
