Dr. Brown's Anti-Colic vs. Comotomo Baby Bottles
Both are top-tier baby bottles solving different problems. Dr. Brown's excels at reducing colic and gas with its internal vent system. Comotomo wins on simplicity, breast-like feel, and easy cleaning. Cost is comparable.
Dr. Brown's Natural Flow Anti-Colic Options+ and Comotomo Silicone Baby Bottles are two of the most recommended bottles by parents and pediatricians. They take fundamentally different approaches — Dr. Brown's engineers air out of the feeding process with an internal vent, while Comotomo mimics the breast with soft, squeezable silicone. The best choice depends on whether your baby struggles with gas or whether you're prioritizing breastfeeding transition.

Two Popular Bottles, Two Very Different Philosophies
Dr. Brown's Natural Flow Anti-Colic Options+ and Comotomo Silicone Baby Bottles sit at the top of nearly every "best baby bottles" list — but they solve different problems.
Dr. Brown's is an engineering solution. Its patented internal vent system creates a vacuum-free feeding experience, channeling air through the vent and away from the milk. The result is less oxidation of milk nutrients, fewer bubbles, and reduced gas and colic symptoms.
Comotomo is a design solution. Its soft, medical-grade silicone body and naturally shaped wide nipple replicate the feel of a breast. The goal is seamless transition between breastfeeding and bottle feeding — without the nipple confusion that derails many combo-feeding plans.
Both are well-made bottles. The right one depends on what problem you're trying to solve.

| Feature | Dr. Brown's Options+ | Comotomo Silicone | What It Means |
|---|---|---|---|
| Manufacturer | Handi-Craft Company | Comotomo Inc. | Dr. Brown's has been around since 1996. Comotomo launched in 2012 with a design-forward approach. |
| Anti-colic system | Internal vent system channels air away from milk | Dual anti-colic vents in nipple | Dr. Brown's is more effective at reducing gas. Its full-length vent is purpose-built for colic. |
| Material | Polypropylene plastic (or glass option) | Medical-grade silicone body | Comotomo's silicone is squeezable and feels skin-like. Dr. Brown's offers both plastic and glass. |
| Nipple design | Narrow or wide-neck, firmer silicone nipple | Wide, naturally shaped soft silicone nipple | Comotomo's nipple mimics the breast more closely. Better for babies switching between breast and bottle. |
| Number of parts | 4–5 parts (bottle, collar, nipple, vent insert, reservoir) | 3 parts (body, collar-nipple, cap) | Comotomo wins on simplicity. Fewer parts means faster assembly and less to lose. |
| Ease of cleaning | Requires bottle brush + vent brush; many small parts | Wide mouth fits your hand inside; dishwasher-safe | Comotomo is substantially easier to clean. This is the most common parent complaint about Dr. Brown's. |
| Sizes available | 2 oz, 4 oz, 8 oz, 9 oz | 5 oz, 8 oz | Dr. Brown's offers more size options, including a small 2 oz preemie size. |
| Nipple flow levels | Preemie, Level 1–4, Y-cut | Slow flow, Medium flow, Fast flow | Dr. Brown's has more flow options. Useful for preemies or babies who need precise flow control. |
| BPA/phthalate free | Yes | Yes | Tie. Both are free of BPA, PVC, and phthalates. |
| Breast-like feel | Rigid bottle, standard nipple | Soft, squeezable body mimics breast | Comotomo is designed to feel like a breast in baby's hands. Helps with latch and transition. |
| Glass option | Yes — borosilicate glass available | No | Parents who prefer glass bottles have Dr. Brown's as an option. Comotomo is silicone only. |
| Dishwasher safe | Top rack only | Yes — fully dishwasher safe | Both can go in the dishwasher, but Comotomo's fewer parts make it simpler. |
The Anti-Colic Question: How Much Does the Vent Matter?
If your baby has colic or significant gas, this is the most important section.
Dr. Brown's internal vent system is the most engineered anti-colic solution on the market. Air enters through a hole in the collar, travels through the vent insert and reservoir tube, and exits into the space above the milk — never mixing with what your baby drinks. This eliminates the vacuum pressure that forces babies to gulp air along with their milk.
Comotomo's approach is simpler: two small anti-colic vents built into the base of the nipple. These allow air to flow into the bottle without baby needing to break the latch, but air still contacts the milk surface.
In practice, parents of severely colicky babies consistently report that Dr. Brown's makes a bigger difference. The internal vent is more aggressive at separating air from liquid. Comotomo's vents reduce some air intake but are not as effective for babies who are serious air-swallowers.
If colic is your primary concern, Dr. Brown's is the stronger pick. If your baby has mild or no gas issues, Comotomo's simpler vents are sufficient.
Cleaning: The Tradeoff Nobody Warns You About
Here is the honest truth about Dr. Brown's: the vent system is a pain to clean.
Each Dr. Brown's bottle has four to five components. The vent insert and reservoir require a tiny brush (included) to clean properly. If milk residue dries inside the vent tube, it can clog and reduce effectiveness. Many parents report that cleaning Dr. Brown's bottles takes two to three times longer than cleaning simpler bottles.
Comotomo, by contrast, has a wide-mouth opening large enough to fit an adult hand inside. Three parts total. No tiny brushes needed. Many parents hand-wash them in under 30 seconds.
This tradeoff — anti-colic performance vs. cleaning convenience — is the core decision. If your baby needs the vent, the extra cleaning is worth it. If your baby doesn't struggle with gas, the cleaning burden is hard to justify.
The good news: Dr. Brown's Options+ lets you remove the vent once your baby outgrows the colicky phase (typically around 4–6 months), turning it into a simpler bottle.

Breast-to-Bottle Transition: Where Comotomo Shines
If you're combo-feeding — alternating between breastfeeding and bottle feeding — nipple confusion is a real concern. Babies who get used to a fast-flowing, firm bottle nipple may start refusing the breast.
Comotomo's wide, soft nipple is shaped to encourage the same wide latch babies use at the breast. The silicone body is squeezable, so babies can knead it the way they would during nursing. Multiple lactation consultants recommend Comotomo specifically for breastfed babies who need to take an occasional bottle.
Dr. Brown's nipples are firmer and more traditionally shaped, especially in the narrow-neck version. The wide-neck version is better for breastfed babies, but the nipple is still not as soft or breast-like as Comotomo's.
If smooth breast-to-bottle transition is your priority, Comotomo has a meaningful advantage here.
| Product | Typical Price | Cost Per Bottle | Nipple Replacements |
|---|---|---|---|
| Dr. Brown's Options+ Wide-Neck (9 oz, 2-pack) | $12–$15 | ~$6–$7.50 | ~$5–$7 per 2-pack |
| Comotomo Silicone (8 oz, 2-pack) | $26–$30 | ~$13–$15 | ~$8–$10 per 2-pack |
| Dr. Brown's Options+ Narrow-Neck (8 oz, 4-pack) | $20–$25 | ~$5–$6.25 | ~$5–$7 per 2-pack |
| Comotomo Silicone (5 oz, 2-pack) | $24–$28 | ~$12–$14 | ~$8–$10 per 2-pack |
Price: Dr. Brown's Is the Budget-Friendly Option
Comotomo bottles cost roughly twice as much per bottle as Dr. Brown's. A full set of 6 Comotomo bottles will run you $75–$90, while 6 Dr. Brown's bottles cost $30–$45.
Replacement nipples are also more expensive for Comotomo ($8–$10 per 2-pack vs. $5–$7 for Dr. Brown's).
That said, most families need only 4–8 bottles total, and bottles last the entire first year if cared for properly. The total cost difference over a year is roughly $40–$60 — real money, but not a huge sum in the context of baby expenses.
A few ways to save:
- Buy starter sets. Both brands offer value packs with multiple sizes and flow levels.
- Watch for registry discounts. Amazon, Target, and Buy Buy Baby registries all offer completion discounts of 10–15%.
- Check secondhand for Comotomo. Silicone is durable and sterilizable. Just replace the nipples.
Choose Dr. Brown's Options+ If
- Your baby is gassy, colicky, or swallows a lot of air during feedings
- You want a clinically proven internal vent system for air reduction
- You prefer a glass bottle option
- Your baby is a preemie and needs precise flow control (Preemie nipple available)
- Budget is a priority — Dr. Brown's costs roughly half per bottle
- You need a wider range of bottle sizes, including small 2 oz options
Choose Comotomo If
- Your baby is transitioning between breast and bottle and you want to reduce nipple confusion
- Easy cleaning is a top priority — you can wash it by hand without a brush
- You want a soft, squeezable bottle that feels natural in baby's hands
- You prefer fewer parts to assemble, clean, and keep track of
- You want a simple, modern design without internal components
- Your baby latches better on a wide, breast-shaped nipple
Where to Buy
If gas and colic are your biggest concern, the Dr. Brown's Natural Flow Anti-Colic Options+ (~$6/bottle in multi-packs) is the gold standard for air-free feeding. The internal vent system is unmatched, and the Options+ line lets you remove the vent later when your baby no longer needs it. The wide-neck version is better for breastfed babies.
If you want the smoothest breast-to-bottle transition and hate cleaning tiny parts, the Comotomo Silicone Baby Bottles (~$13/bottle) are worth the premium. The squeezable silicone body, breast-shaped nipple, and three-part design make feeding feel natural and cleanup feel effortless.
Our honest advice: if your baby has colic, start with Dr. Brown's. If your baby is healthy and you're combo-feeding, start with Comotomo. Many families end up owning both.

The Bottom Line
Dr. Brown's Natural Flow Anti-Colic Options+ and Comotomo Silicone Baby Bottles are both excellent — but they're built for different situations.
Dr. Brown's wins on anti-colic performance, price, size range, and flow-level options. The internal vent system is the most effective air-reduction technology available in a baby bottle.
Comotomo wins on ease of cleaning, breast-like feel, latch quality for breastfed babies, and overall simplicity. It is the better bottle for combo-feeding families who don't have a colic problem to solve.
The best approach: match the bottle to your baby's biggest need. Colic and gas point to Dr. Brown's. Breast-to-bottle transition points to Comotomo. And if your baby is happy with either, the simpler bottle (Comotomo) will make your life easier at 3 AM.
If you are tracking feeding amounts and frequency — which is especially helpful in the newborn weeks — tinylog makes it easy to log bottles and spot patterns over time.
