Lansinoh Silicone Baby Bottle Nipples, Fast Flow, Size F, 2ct
Lansinoh NaturalWave Baby Bottle Nipples (Fast Flow, Size F) Review
A Breastfeeding-Friendly Bottle Nipple That Truly Understands Babies
When you’re navigating the early months of parenthood, few things matter more than feeding. Whether you’re exclusively breastfeeding, combination feeding, or transitioning between breast and bottle, finding the right bottle nipple can make all the difference. A poor choice can lead to frustration, nipple confusion, gas, spit-up, or even feeding refusal. A good choice, on the other hand, can bring peace of mind—and smoother feedings—for both baby and parent.
That’s where Lansinoh NaturalWave Baby Bottle Nipples come in.
Trusted by breastfeeding moms for over 35 years, Lansinoh has built a reputation around products that genuinely support natural feeding. Their NaturalWave Bottle Nipples, particularly the Fast Flow (Size F, 6+ months) version we’re reviewing today, are designed to closely mimic breastfeeding while addressing common bottle-feeding challenges like colic and nipple confusion.
In this in-depth review, we’ll explore exactly what makes these nipples special, who they’re best for, their pros and cons, and whether they’re worth adding to your baby-feeding setup.

Why Bottle Nipples Matter More Than You Think
Before diving into features, it’s important to understand why choosing the right nipple is so critical—especially for breastfed babies.
Breastfeeding involves a complex feeding action: babies must latch deeply, use their tongue in a wave-like motion, and coordinate sucking, swallowing, and breathing. Many standard bottle nipples allow milk to flow too easily, teaching babies a completely different feeding technique. This can lead to nipple confusion, where babies begin to prefer the bottle over the breast.
Lansinoh designed NaturalWave nipples specifically to address this problem.
Key Features and Benefits (In-Depth Analysis)
1. Clinically Proven to Reduce Nipple Confusion
One of the biggest selling points of Lansinoh NaturalWave nipples is that they are clinically proven to reduce nipple confusion.
Unlike traditional bottle nipples that encourage shallow latching and passive milk flow, NaturalWave nipples require babies to actively suck—just like they do at the breast. This makes it easier for babies to switch back and forth between breast and bottle without frustration.
Why this matters:
If you’re pumping at work, supplementing occasionally, or sharing feeding duties with a partner, this feature alone can be a game-changer.
2. Encourages Natural Oral Development
Lansinoh didn’t just focus on feeding—they also considered long-term oral health.
The NaturalWave nipple design supports:
Proper tongue movement
Natural jaw motion
Healthy palate and tooth development
The nipple is soft and flexible, allowing optimal compression rather than forcing milk out too quickly.
Benefit:
Your baby develops feeding skills that align with natural breastfeeding mechanics, rather than adapting to an artificial flow pattern.
3. Advanced Anti-Colic Air Ventilation System (AVS)
Gas, colic, and spit-up are among the most stressful feeding-related issues parents face. Lansinoh tackles this with its Air Ventilation System (AVS).
The AVS reduces the amount of air your baby swallows during feeding, which can help:
Minimize gas
Reduce spit-up
Lower the risk of colic discomfort
Real-world impact:
Fewer interruptions during feeds, less post-feeding fussiness, and more comfortable tummies—especially important as babies begin taking in larger volumes with fast-flow nipples.
4. 100% Soft, Durable Silicone (BPA & BPS Free)
Safety is non-negotiable when it comes to baby products, and Lansinoh delivers here.
These nipples are made from:
100% food-grade silicone
Free from BPA and BPS
Soft enough to mimic natural skin feel
Durable enough to withstand frequent sterilization
Why parents love this:
You get peace of mind knowing your baby isn’t exposed to harmful chemicals, while still enjoying a nipple that feels natural and lasts through daily use.
5. Fast Flow (Size F) for Growing Babies (6+ Months)
As babies grow, their feeding needs change. The Fast Flow (Size F) nipple is designed for babies 6 months and older who can handle a quicker milk flow.
This is especially useful for:
Babies who become frustrated with slower flow nipples
Feeding thicker liquids (with pediatrician approval)
Older breastfed babies who feed more efficiently
Important note:
This specific listing is for fast flow nipples, even though Lansinoh also offers slow and medium flow options.
6. Simple, Easy-to-Clean Design
With fewer parts than many anti-colic bottle systems, Lansinoh nipples are:
Easy to assemble
Simple to clean
Dishwasher-safe (top rack)
Busy parents will appreciate that these nipples don’t add extra complexity to their daily routine.
