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 older Parents looking for a faster-flow nipple for bottle-feeding Reducing gas and colic with the vented system Convenient and easy-to-clean bottle-feeding solution Final 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.

Pros • My baby prefers this over the bottles we started with because it is softer and easy to suck on and with multiple holes • Works really well with the Dr. Brown’s system • Flow seems comfortable for babies who need a slower pace Cons • More parts to clean compared to some other bottles Overall, my baby really likes these. We started with Avent bottles, but she seemed to do much better with the Dr. Brown’s ones.

I recently switched to Dr. Brown's Natural Flow Level 4 Narrow Baby Bottle Silicone Nipple for my 9-month-old, and it's been a total game-changer for our feeding routine. The silicone feels soft and natural, providing a comfortable feeding experience for my little one. Knowing it's made from 100% silicone gives me peace of mind about any potential harmful chemicals. The fast flow rate is just right for my growing baby who needs a bit more speed during feeds. It's made our feeding times more efficient and reduced fussiness. Transitioning from the Level 3 nipple was smooth, and my baby took to it with ease. Plus, the unique anti-colic design has noticeably reduced post-feeding discomfort. The 6-pack offers great value for money, ensuring I always have a clean, ready-to-use nipple available. Cleaning is a breeze thanks to the wide opening at the base. In a nutshell, Dr. Brown's Natural Flow Level 4 Narrow Baby Bottle Silicone Nipple has surpassed my expectations. It's a top-notch, reliable product that has made feeding time a breeze for both me and my baby. I highly recommend these nipples to parents of active, growing infants. They truly deliver on their promise of a natural, comfortable, and colic-reducing feeding experience.

We have been using Dr. Brown’s bottles from the beginning, and the Size 4 nipple has worked really well as our baby grew. The flow is perfect for an older baby who feeds faster, and it helps reduce fussiness during feeding. The quality is excellent, just like all Dr. Brown’s products, and it fits perfectly with the bottles. Easy to clean and durable too. Definitely a good product and worth buying if your baby is ready for the next flow level.

I bought these Dr. Brown's Original Nipples because my kid decided that the Level 3 flow was "insultingly slow" and started looking at me like I was personally withholding his inheritance. We moved up to Level 4, and holy hell, it’s like I installed a turbocharger on a tricycle. This isn't just a nipple; it’s a high-pressure fire hose for infants who have places to be and milk to demolish. I watched my son finish a bottle in approximately four seconds, after which he stared at the ceiling in a milk-induced trance, questioning the fabric of reality. The "9m+" label is basically a warning that your child is now a professional athlete in the sport of hydration. If you’re tired of your baby acting like they’re trying to drink a milkshake through a coffee stirrer, these are the answer. Just be prepared for the burps that follow—they sound like a grown man who just finished a liter of soda at a tailgate. It’s effective, it’s slightly terrifying, and it’s the only way I get to sit down for more than five minutes. 5/5 stars for the speed, the efficiency, and the absolute chaos it has introduced to our feeding schedule.

Good quality and all nipples were delivered, but the packaging was not properly secured.

Muy buena calidad

These Dr. Brown’s Natural Flow nipples are amazing! They fit perfectly with the bottles and help reduce gas and colic, which has made feeding time so much smoother for my little one. The flow is consistent, and the nipples are soft, mimicking the natural feel of breastfeeding. Cleaning them is easy, and they’re durable enough to last without any issues. I’ve noticed a significant improvement in my baby’s comfort during and after feedings. If you’re looking for reliable and high-quality nipples, these are definitely a great choice for your baby!

My child loves them and they are expensive in shops so ordering it convenient Fast delivery

This is my fourth time ordering—only the nipple size is different. I've never felt the need to switch to another brand. Both the bottles and nipples are made of excellent quality.
