Made of super-soft, 100% silicone, the Level 3 Nipple fits all Dr. Brown’s® narrow bottles. The suggested age range for the Level 3 Nipple is 6 months+, but baby’s preferred flow rate may vary. Safe for use in dishwasher (top rack only), electric and microwave sterilizers or boiling water. BPA free.

Review: Great Next Size up from 1 to 2 - We needed to move up from the Level 1 nipple for our 2‑month‑old, and the Dr. Brown’s Natural Flow Level 2 Narrow has been perfect. The flow is just right—not too fast, not too slow—and our baby adjusted immediately with no issues. The quality is exactly the same as the originals that came with our Dr. Brown’s bottles, so everything feels familiar and reliable. They fit both our glass and plastic bottles without any compatibility problems, which made the switch super easy. If you’re looking for the next size up, these are a great choice. Consistent quality, no leaks, and a happy baby. Highly recommend!
Review: Perfect Replacement Nipples - Great Quality and Flow - These Dr. Brown's Level 2 silicone nipples are excellent replacement nipples for our baby bottles. We use Dr. Brown's bottles exclusively, and having spare nipples on hand has been essential. Perfect Fit: These nipples fit our Dr. Brown's Natural Flow narrow bottles perfectly. They screw on securely with no leaks or issues. The compatibility is exactly as expected from the official Dr. Brown's replacement parts. Medium Flow - Level 2: The Level 2 medium flow is ideal for our growing baby. It's the perfect progression from Level 1 once our baby got more efficient at feeding. The flow rate allows our baby to feed at a comfortable pace without getting frustrated or overwhelmed. No choking, no excessive air intake, just smooth feeding. Quality Silicone: The silicone material is soft, durable, and high-quality. It feels safe and comfortable for our baby. The nipples don't show signs of wear even after multiple uses and dishwasher cycles. They maintain their shape and integrity well. Easy to Clean: The silicone nipples are easy to clean and sanitize. They're dishwasher safe (top rack) and also hold up well when hand washing. They don't retain odors or discoloration, which is important when using them daily. Great Value with 100-Pack: Getting 100 nipples in this pack is fantastic value. It means we can: - Replace nipples regularly for hygiene purposes - Always have clean ones ready - Not worry about running out - Have backups for travel or daycare The cost per nipple works out to be very reasonable compared to buying smaller packs. Consistent Performance: Every nipple in the pack has performed consistently. No defects, no issues with flow rate variations. They all work exactly as they should. Practical for Parents: As someone who prepares multiple bottles throughout the day and night, having a good supply of nipples means less stress. I can prep several bottles at once and not worry about having to wash and reuse nipples immediately. Compatibility Note: These are for the narrow neck Dr. Brown's bottles (not the wide neck bottles). Make sure you're getting the right size for your bottles. They fit the bottles we have perfectly. Why Replacements Are Important: Nipples are recommended to be replaced every 2-3 months or when they show signs of wear. Having this supply means I can follow those guidelines without constantly reordering. Highly recommend these replacement nipples to any parent using Dr. Brown's narrow bottles. The quality, flow rate, and value make this a must-have purchase for maintaining a good feeding experience for your baby.

## Questions & Answers

**Q: Do these fit the Ameda bottles?**
A: They do fit but, they are not vented like all other brand nipples. So it would only work with dr brown system or rings. With my Ameda bottles and nfant rings, Dr brown nipples collapse because of no-ventilation problem.

**Q: can the level 3 nipple fit the level 1 colic bottles? Or do I need to purchase level 3 bottles to be compatible with the level 3 nipple?**
A: All the Dr. Brown's narrow nipple flows are compatible with the Dr. Brown's 4 oz. and 8 oz. narrow bottles including the level 3 shown in this post.

**Q: Do these nipples work in phlips avant anti colic bottles**
A: I’m not sure . We got these for the dr Browns bottles but if they are the same size I don’t see why not .

**Q: Are the preemie nipples shorter than the regular nipples?**
A: The lengths are the same. The preemie just has a smaller hole and thus a slower flow. My kiddos were born at 28 weeks and once they graduated to bottles they took the preemie nipples just fine.

### ⭐⭐⭐⭐⭐ Reliable Next-Stage Nipples with Great Quality and Easy Transition for Growing Babies
*by L***Y on January 8, 2026*

We’ve been using Dr. Brown’s narrow bottles from the beginning, so moving up to the Level 2 nipples was a natural next step. They’ve worked really well for my baby — the flow is just right for a growing infant who has outgrown the newborn level but still needs a controlled, comfortable pace. The quality is consistent across each nipple, and the silicone feels soft yet durable, which many reviewers also highlight. One of the biggest advantages is compatibility. If you’re already invested in Dr. Brown’s bottles, upgrading only the nipples instead of buying new bottles saves time and money. I’ve purchased multiple packs already, and every nipple fits perfectly with the existing narrow bottles. They’re easy to clean, dishwasher safe, and hold up well after repeated sterilizing. The anti-colic system continues to work smoothly with this nipple level. Feedings stay comfortable with less gas and fewer burping issues. The breast-like shape also makes the transition between bottle and breast easier — something a lot of parents appreciate, and I’ve experienced the same ease in switching. On the downside, some recent medium and low reviewers mention occasional leaking, and I’ve noticed small leaks too if the bottle isn’t tightened exactly right. It’s not a deal-breaker, but it’s something the brand could improve to make the experience more seamless, especially during nighttime feeds. Overall, the nipples are well‑made, safe, and very portable — easy to carry as backups in the diaper bag. For babies who are growing and need a slightly faster flow, Level 2 is a reliable step forward. What I liked • Great quality and comfortable silicone material • Perfect next-stage flow for growing babies • Works with existing Dr. Brown’s narrow bottles — very convenient • Helps maintain anti-colic benefits and smooth feeding • Easy to clean, sterilize, and travel with • Encourages an easy latch similar to breastfeeding What could be better • Occasional minor leaking if not tightened perfectly • Packaging could be more secure for long-term storage of extra nipples
