This nipple is the next step up after a preemie nipple but BEFORE the level 1. A great transition to a bit faster flow. If baby is showing stress cues when moving up to this flow, it could be too fast.

One nipple, not a set.

Made of super-soft, 100% silicone, the Transition Flow Nipple fits all Dr. Brown’s narrow bottles. Safe for use in dishwasher (top rack only), electric and microwave sterilizers or boiling water. BPA free.
