Dr. Brown's baby

Dr. Brown’s® Level 4 Nipple is our fastest flow nipple for 9m+. Dr. Brown’s uniquely designed Natural Flow® Options+™ Level 4 Nipple is a fast flow nipple, great for feeding more aggressive eaters. The breast-like shape encourages a proper latch for a more natural bottle feeding experience. Perfect for switching from breast to bottle and back again! Designed alongside medical professionals, the correctly contoured nipple shape and high-grade, soft silicone offer a more comfortable feeding experience and help to avoid nipple confusion. Together with the anti-colic internal vent system, the Level 4 Nipple gives baby vacuum-free feeding that is clinically proven to reduce colic, decrease spit-up, burping and gas. While our bottle works best with the vent system, it’s great to have options when baby’s feeding develops. Just remove the vent and the feeding experience is similar to most nipple-vented bottles. Level up to faster nipple flow rates as baby grows! Fits Dr. Brown’s® Natural Flow® Options+™ Narrow bottles. Dishwasher (top rack) and sterilizer safe. BPA free.
