Dr. Brown's Options+ vs. Philips Avent Natural

Dr. Brown's Natural Flow Anti-Colic Options+ and Philips Avent Natural are both excellent baby bottles. They're both in millions of nurseries for a reason. But they solve the gas-and-colic problem in fundamentally different ways, and the differences matter depending on your baby.

Here's the honest version: Dr. Brown's is the harder-core anti-colic bottle. It has an internal vent system that genuinely separates air from milk, and it works. The tradeoff is more parts, more cleaning, and more opportunities for leaky assembly at 2 AM when your hands are shaking from sleep deprivation.

Philips Avent Natural is the easier bottle with a great anti-colic valve and a breast-shaped nipple that makes life easier for breastfed babies going back and forth between breast and bottle. It's simpler to clean, simpler to assemble, and less likely to leak. But for truly gassy babies, it may not be enough.

The truth nobody puts on the box: some babies are picky and you may need to try both. Buy one pack of each before committing to a full set. Your baby gets the final vote.

This is the biggest difference between these two bottles, and probably why you're reading this.

Dr. Brown's internal vent system is a two-piece mechanism (vent insert + reservoir tube) that sits inside the bottle. As baby feeds, air enters through the collar and travels through the vent system into the back of the bottle — completely bypassing the milk. This creates positive pressure that eliminates the vacuum effect, which means baby swallows less air and gets a more consistent flow.

The result: less gas, less colic, less spit-up. Multiple studies support this. Parents of seriously colicky babies consistently rate Dr. Brown's as one of the most effective bottles for reducing gas-related crying.

Philips Avent's approach is less aggressive but still effective. The Natural bottle has a one-way anti-colic valve built into the nipple ring. During feeding, air flows into the bottle through the valve while milk flows out through the nipple — keeping them separated. It works, but the separation isn't as complete as Dr. Brown's internal system.

Avent also sells an AirFree vent as a separate accessory. When attached, it keeps the nipple full of milk even when the bottle is horizontal, reducing air intake. If your baby has moderate colic and you like the Avent design, the AirFree vent is worth trying before switching bottles entirely.

The honest call: If your baby has serious colic, Dr. Brown's internal vent is the more effective system. If your baby has mild gas or you're trying to prevent colic, Avent's built-in valve may be all you need.

Nipple shape is the sleeper factor that trips up a lot of parents.

Dr. Brown's uses a narrow, traditional nipple. It works well and babies latch onto it fine — but it doesn't closely resemble the shape of a breast. For exclusively bottle-fed babies, this is a non-issue. For babies going back and forth between breast and bottle, the narrow shape can sometimes cause nipple confusion.

Philips Avent Natural uses a wide, breast-shaped nipple with their Natural Response system. The nipple only releases milk when baby actively sucks — and pauses when baby pauses to swallow and breathe. This mimics the rhythm of breastfeeding more closely than a constant-flow nipple.

If your baby is breastfed and you're introducing bottles, Avent's wider nipple is generally the better starting point. The shape and demand-based flow make the breast-to-bottle transition smoother for most babies. This isn't marketing fluff — lactation consultants frequently recommend wide-neck bottles for breastfed babies.

That said, plenty of breastfed babies take Dr. Brown's narrow nipple without any drama. Babies are individuals. If one doesn't work, try the other.

Nobody talks enough about cleaning when recommending baby bottles. You will wash bottles 8–12 times a day in the early months. The difficulty of cleaning your bottles will directly affect your quality of life.

Dr. Brown's Options+ has 5–7 separate parts per bottle: the bottle body, nipple, collar, vent insert, reservoir tube, travel disc, and cap. The vent insert and reservoir tube are small, oddly shaped, and need a dedicated tiny brush (included in most starter kits, thankfully). Milk residue builds up inside the reservoir tube, and if you don't scrub it out, it gets funky fast.

We're not going to sugarcoat this: washing Dr. Brown's bottles is annoying. It's the number-one complaint in parent reviews, and it's valid. When you're already exhausted and your sink is full of bottle parts that look like they belong in a chemistry set, the frustration is real.

Philips Avent Natural has 3–4 parts: bottle, nipple, screw ring, and cap. The wide neck means you can get a standard bottle brush inside without contorting your wrist. There are no internal vents to disassemble and scrub. You can have an Avent bottle washed, dried, and reassembled in a fraction of the time.

The tradeoff is clear: Dr. Brown's anti-colic performance comes at the cost of cleaning convenience. If your baby genuinely needs the vent system, the extra cleaning is worth it. If your baby's gas is manageable, Avent's simplicity will save you meaningful time and sanity.

One more thing: the Options+ "plus" in Dr. Brown's name refers to the fact that you can remove the vent system once your baby outgrows the need for it. When you do, the bottle drops down to a normal number of parts. So the cleaning burden is temporary — if your baby cooperates.

Both bottles are in the same ballpark. Dr. Brown's is typically $1–$2 cheaper per bottle in plastic multi-packs. Philips Avent is slightly more expensive but you're not buying replacement vent parts down the road.

The real cost difference is in replacement parts and accessories. Dr. Brown's vent inserts and reservoir tubes wear out and need replacing. Avent's simpler design means fewer replacement parts to buy. Over a year of bottle feeding, this can add up to $15–$30 in extra parts for Dr. Brown's.

The smart move for either brand:

• Buy a starter pack first (2–4 bottles) to make sure your baby accepts the nipple
• Then buy in bulk once you know it works
• Watch for sales — both brands run frequent promotions on Amazon, Target, and at warehouse clubs
• Don't overbuy nipple levels — buy the next level up only when baby seems frustrated with flow speed

If colic is your main concern, the Dr. Brown's Natural Flow Anti-Colic Options+ (~$5–$7/bottle in a 4-pack) is the gold standard for reducing gas and spit-up. The internal vent system is the most effective anti-colic design on the market. Yes, there are more parts to clean — but when your baby stops screaming after feeds, you will not care about the extra 30 seconds of scrubbing.

If you want easier cleaning and a smoother breastfeeding transition, the Philips Avent Natural Baby Bottles (~$6–$8/bottle in a 4-pack) are hard to beat. The wide breast-shaped nipple, Natural Response flow system, and 3-part simplicity make daily feeding less stressful. Add the AirFree vent if gas becomes an issue.

Our honest advice: buy a small pack of each. The "right" bottle is whichever one your baby accepts and that keeps gas manageable — and you will not know until you try.

Both Dr. Brown's Options+ and Philips Avent Natural are excellent bottles backed by solid engineering and millions of happy parents. The differences are real and meaningful:

Dr. Brown's Options+ wins on anti-colic performance, proven vent technology, and the ability to remove the vent as baby grows. It's the bottle to reach for when colic is severe and you need the most aggressive air-reduction system available.

Philips Avent Natural wins on ease of use, fewer parts, easier cleaning, a more breast-like nipple for breastfed babies, better part interchangeability, and fewer leaks. It's the bottle to reach for when you want effective colic prevention without the daily cleaning hassle.

For most families, here's the real decision tree: Is your baby's colic bad enough to justify washing extra parts 8+ times a day? If yes, Dr. Brown's. If your baby's gas is mild or you're prioritizing the breast-to-bottle transition, Avent.

And if your baby rejects both? That's normal. Babies are tiny, opinionated humans. Try a different nipple flow rate before switching brands entirely — sometimes the issue is flow speed, not bottle design.
