Dr. Brown’s Natural Flow Level 2 Narrow Baby Bottle Silicone Nipple, Medium Flow, 3m+, 100% Silicone Bottle Nipple, 6 Count

I’ve been using Dr. Brown's Level 4 Nipples for a while now, and I’m so happy with them! These nipples are a perfect fit for my growing baby and have made feedings much smoother and more comfortable. Here’s what I love about them:Flow Rate & Feeding Ease:The Level 4 nipples are designed for babies 9 months and up, and they provide a faster flow, which is exactly what my little one needs as she gets more efficient at feeding. My baby doesn’t get frustrated anymore waiting for milk to come out slowly, and I feel like she’s able to drink more without getting too tired. It’s the perfect balance—fast enough to keep her happy but not so fast that she’s overwhelmed. The flow is great for bottles with thicker liquids (like formula or breast milk with added supplements) and for babies who are ready to drink more quickly.Compatibility & Durability:These nipples work perfectly with Dr. Brown’s bottles, and I love how easy they are to clean and maintain. They’re durable and hold up well over time, even with regular sterilization. I haven’t noticed any wear and tear, and the nipples continue to function as well as they did on day one.Design & Comfort:Like all Dr. Brown's nipples, the Level 4 nipples are designed with a vent system that helps reduce gas and colic, which has been a huge benefit for us. My baby has had less discomfort during and after feedings, and the air venting system seems to work well at reducing any gassy buildup. The silicone is soft but sturdy, and my baby is able to latch on comfortably without any issues.Ease of Use:The nipples are easy to screw on and off, and they fit snugly into the bottle without leaking. The fast flow doesn’t cause any mess, and I don’t have to worry about milk spilling everywhere. They’re a hassle-free addition to our bottle-feeding routine.Perfect For:Babies 9 months and olderParents looking for a faster-flow nipple for bottle-feedingReducing gas and colic with the vented systemConvenient and easy-to-clean bottle-feeding solutionFinal Thoughts:The Dr. Brown’s Level 4 Nipples have been a game-changer for us! They’re fast, functional, and help reduce discomfort during feedings, which has made a noticeable difference for my baby. I feel like we’ve reached a feeding sweet spot, and I highly recommend these nipples for any parents whose babies are ready for a faster flow. If you’re already using Dr. Brown's bottles, these nipples are a must-try.

Honestly, I didn’t think a nipple would make that much of a difference, but here we are. My baby was struggling with other brands — either the flow was too fast, or the nipple would collapse and frustrate her. I switched to the Dr. Brown’s Level 1, and wow. She latched right away, no gagging, no air bubbles, just a calm, happy feeding (finally).It’s soft but doesn’t lose shape, and it holds up well even after being washed a million times. I usually just toss it in the top rack of the dishwasher and it’s good to go.One thing I didn’t realize until later — if your baby starts getting fussy again, it might be time to size up the flow. We switched to Level 2 at around 3 months and it made a big difference. Wish I had known that earlier!If you’re a tired mom just trying to get through the day with fewer feeding battles, these are so worth it. Game changer for us.

So happy that these are compatible with Munchkin Bond Silicone Glass Bottles! We wanted a slower flow nipple to go with the Munchkin bottles since our son has reflux and thought the Dr. Brown ones might work since the bottles are so similar. They are a perfect fit and the Dr. Brown premie nipple is way slower than the Munchkin 1 nipple. Also more convenient than buying replacement nipples from Munchkin since they can only be purchased on their website/are not on Amazon as of now. Thought we’d let other parents know about the swap!

We transitioned to Dr. Brown's Level 3 bottle nipples for our baby a couple of months ago and couldn't be happier! These products really helped our baby take less time with the bottle, which is a huge win. We also love that they're dishwasher safe and, of course, reasonably priced. Another great Dr. Brown's product!

As a parent, finding bottle-feeding supplies you can trust from day one is a game-changer—and Dr. Brown’s nipples have been that for us. We started with Level 1 when our baby was a newborn, moved up through the levels as he grew, and now that we’re on Level 3, I can say these nipples have made every stage of feeding so much smoother.🔹 Flow That’s Just RightLevel 3 is perfect for 6-month-olds and up—fast enough for a growing baby who’s more efficient at feeding, but still gentle enough to avoid choking or gas. The gradual increase in flow through each stage really helped us transition easily without overwhelming our baby.🔹 No Leaks, No FussThey fit perfectly and seal tightly with all Dr. Brown’s Original Narrow Bottles (not the Wide-Neck versions). We’ve never had issues with leaking, collapsing nipples, or feeding discomfort. They also hold up beautifully through constant washing and sterilizing—very durable.🔹 6-Pack = Peace of MindWith how often babies eat (and how fast they go through clean bottles), the 6-count pack has been a lifesaver. I always have clean spares ready, especially during those middle-of-the-night feeds.🔹 Why New Parents Will Love TheseIf you’re building your baby feeding setup, know that these nipples are:Compatible with Dr. Brown’s Original Narrow BottlesPart of a flow-level system that grows with your babyDesigned to work seamlessly with Dr. Brown’s anti-colic vent system, which truly helped reduce gas and fussiness for us💬 Final Thoughts:After trying a few options early on, we always came back to Dr. Brown’s. These nipples are thoughtfully designed, reliable, and gentle on little tummies. If you want a stress-free, trusted feeding solution from newborn stage onward, this is the one to get.

It’s hard to find a big pack of these nipples in store, so I’m thankful I can get a bigger pack online. I moved my daughter to this size around the time she made 3 months and she’s now drinking her bottles much faster. They’ve held up well from the dishwasher too.
