Key item features

  • THICKER LIQUIDS FOR BABY. Dr. Brown's Y-Cut Nipple is the perfect step when baby is ready for thickened milk, formula or cereal.
  • ANTI-COLIC BABY BOTTLE WITH NIPPLE. Y-Cut Nipple, with Anti-Colic internal vent system, is clinically proven to reduce colic. Decreases spit-up, burping and gas and provides a more comfortable feeding experience for baby.
  • CONSISTENT FLOW RATE. Vacuum-free feeding is closest to breastfeeding and Dr. Brown's Y-Cut Nipples provide a consistent flow so babies can feed at their own pace.
  • DEPENDABLE NIPPLE FLOW. Each nipple level provides clinical consistency within the flow rate, so baby's feeding experience is constant and comfortable.
  • BREASTFEEDING SILICONE NIPPLE. The breast-like nipple shape encourages a proper latch for a more natural bottle feeding experience and eases the transition from breast to bottle and back again.
  • PRESERVES NUTRIENTS. The Y-Cut Nipple and Anti-Colic vent system is proven to help preserve bottle milk nutrients and aid in digestion for a better night's sleep.
  • SOFT 100% SILICONE. Silicone nipple fits all Dr. Brown's narrow bottles.
  • DISHWASHER SAFE. Safe for use in dishwasher (top rack only), electric and microwave sterilizers or boiling water. BPA Free.

Super slow! Perfect for all ages

Slowest nipple! Wish I had used it sooner as it saved my breastfeeding journey when baby started getting distracted and preferred fast flow. Got him back interested in nursing more often and were going strong at 9 months postpartum, still on this ultra preemie nipple. Does not mimic human nipple but considering how slow it is and how affordable, it's still very much worth it. Does not leak. In fact, I have used the same bottles and nipples for all three of my children (3 under 3) I never had an issue except for maybe one time.

Great item

Great item. Similar quality and effectiveness to other Dr. Brown's products. Paired this with a multi pack of 8 oz bottles. Wish you could buy the multi pack of bottles with any size of nipple so you don't have to make two purchases and have extra nipples in a size you don't need. But that isn't an issue related to this product.
