How To Choose The Best Anti Gas Baby Bottles
Every bottle on this list reduces air intake, but they do it differently. Here is what matters most when making your choice.
Venting System: Where Does The Air Go?
Some bottles use an internal tube or straw (like Dr. Brown’s), others vent through the base (like MAM), and some integrate the vent into the nipple itself (like Nanobebe). An internal vent system is very effective but adds extra parts to wash. Base vents are easier to clean but can leak if not assembled correctly. Nipple vents are the simplest but may not match the air reduction of a multi-part system.
Nipple Shape and Flow Rate
A nipple that mimics the breast helps with latch, especially if you are mixing breastfeeding and bottle feeding. The flow rate matters too: a slow flow (Level 1 or “Slow”) is best for newborns so they do not gulp and swallow air. Too fast a flow can overwhelm a newborn and cause more gas.
Material: Plastic, Silicone, or Glass
Plastic bottles (like Dr. Brown’s and Pigeon PPSU) are lightweight and shatterproof, good for on-the-go. Silicone bottles (like Nanobebe) are soft, flexible, and naturally grippy. Glass bottles (like Gulicola) are toxin-free and easy to clean but heavier — better for home use and less ideal for a baby learning to hold their own bottle.
Cleaning and Assembly
Bottles with fewer parts assemble faster and are less likely to leak. A bottle with 3-4 parts (nipple, ring, bottle) is the easiest daily choice. Bottles with 4 parts (MAM) or 5+ parts (Dr. Brown’s) do a great job on gas but require a small brush and patience. If convenience is your top priority, a silicone or simple vented bottle might suit you better.

In‑Depth Reviews
1. MAM 9oz Easy Start Anti-Colic+ Wide Neck Vented Baby Bottle
See price on AmazonA dual-vent system that is Clinically proven to reduce colic symptoms in 80% of babies..
The key to this bottle is its vented base, which MAM says prevents air from entering the bottle. The SkinSoft silicone nipple is designed to mimic mom’s feel and shape, with MAM claiming a 94% nipple acceptance rate. This makes it a strong pick if you are mixing breastfeeding and bottle feeding, since the baby is less likely to reject the bottle altogether.
Buyers report that these bottles prevent nipple inversion and that the self-sterilizing feature (3 minutes in the microwave, stays clean for up to 48 hours) is a huge time-saver during night feeds.
The catch is the 4 parts to assemble — one reviewer noted that misassembly causes leaks. And unlike the Tommee Tippee, the MAM does not come in a large multi-pack, so you may need to buy a few sets.
Vented anti-colic
- Vented base clinically proven to reduce colic symptoms
- Self-sterilizes in 3 minutes, stays clean 48 hours
- High nipple acceptance makes breast-bottle switching easier
Wide nipple fit
- 4 parts to assemble; leaks if misaligned
- No 1 oz measurement markings, according to one buyer
Best for gas: This is This is the most well-rounded anti-gas bottle for most families. — the vent system works, the nipple mimics breastfeeding well, and the self-sterilizing feature simplifies daily life.
Skip if narrow: If you hate multi-part bottles and want the absolute easiest clean-up, the simpler Nanobebe or Tommee Tippee bottles are a better fit.
2. Dr. Brown’s Natural Flow Anti-Colic Options+ Narrow Baby Bottle, 8 oz
$20.37$24.99as of Jul 5, 12:06 AMThe internal vent system that parents turn to when nothing else calms the gas.
Dr. Brown’s uses a thin internal tube inside the bottle that creates a vacuum-free feeding environment. This prevents air from mixing with the milk, which reduces colic, spit-up, burping, and gas. It is by far It is the most proven anti-colic system on the market. — but it comes at the cost of extra parts to wash. The Level 1 slow flow nipple is ideal for newborns, as owners mention it provides a consistent flow closest to breastfeeding.
Customers note that the Options+ bottle works best with the vent system in place, and that leaks almost always happen when the bottle is filled above the line. One reviewer praised it as the only bottle that minimized gas for their tiny baby. Compared to the Philips Avent, the Dr. Brown’s offers a narrower nipple that some babies latch onto more easily, though it lacks the breast-shaped feel of the MAM or Nanobebe.
The biggest trade-off is cleaning — the internal vent system has multiple small parts that require a dedicated bottle brush. If you are willing to put in the effort, the gas relief is tough to top.
Internal vent system
- Vacuum-free feeding significantly reduces gas and fussiness
- Consistent flow rate for paced feeding
- Vent system can be removed as baby grows
Extra parts clean
- Many small parts — requires a brush and patience to clean
- Leaks if filled above the line
Best for colic: Your baby has persistent colic or reflux and you are willing to wash extra parts for noticeable relief.
Skip if simple: You value quick clean-up — the Nanobebe silicone or Tommee Tippee are far simpler.
3. Nanobebe Flexy Silicone Baby Bottle, Anti-Colic, 5 oz
See price on AmazonA soft silicone bottle with a three-way vented nipple that skips the extra parts.
The Nanobebe Flexy is made from the highest-grade silicone — naturally hygienic, soft, and easy to grip. The anti-colic system sits entirely in the nipple: a 360° triple vented design that prevents the nipple from collapsing and keeps the latch sealed so your baby does not swallow air. Reviewers point out the wide opening prevents mess and significantly reduces gas.
Unlike the Dr. Brown’s, which needs 5 parts to wash, the Nanobebe has just 3 (bottle, ring, nipple). And unlike the MAM, there is no base to unscrew or tiny valve to track. One buyer mentioned the updated design fixes previous issues — the base is now non-detachable, so there is no chance of losing a piece. The 5 oz capacity versus the Tommee Tippee 9 oz means it is better suited for newborns and smaller feeds.
The main limitation is capacity: at 5 oz, you will need to size up to the 9 oz version as your baby grows. And the silicone material, while soft, can tip over more easily than a weighted plastic base.
Flexible silicone body
- Only 3 parts to wash — one of the simplest anti-colic designs
- Soft silicone is easy for baby to hold and feels like skin
- Leak-proof even when upside down (per buyer reports)
Warm milk uneven
- 5 oz capacity is small for older babies (upgrade to 9 oz)
- Soft base can tip over on uneven surfaces
Best for grip: Parents who hate cleaning tiny bottle parts and want a nearly indestructible silicone bottle that reduces gas without the assembly headache.
Skip if rigid: You need a 9 oz bottle from day one — the Tommee Tippee or MAM offer larger capacities right away.
4. Philips Avent Natural Baby Bottles with Natural Response Nipples, 4 oz
$19.90as of Jul 5, 12:06 AMThe bottle that lets baby control the flow, just like nursing.
The Philips Avent Natural bottle uses a “Natural Response” nipple — milk only flows when your baby actively drinks. When they pause to swallow or breathe, the flow stops. This mimics breastfeeding more closely than standard nipples, and the anti-colic valve in the nipple keeps air away from the tummy. Shoppers say the nipple is soft like a breast, so breastfed babies do not reject it. One owner reported their baby actually takes the bottle without screaming, which is a huge win for parents trying to share feeding duties.
That is fine for newborns but you will need to size up quickly. The wide neck makes filling and cleaning easy, and the no-drip nipple design means less wasted milk when the bottle is tilted. It also won the “Best Bottle for Newborns” award from The Bump in 2024.
The limitation is the flow: at Flow 2 (slow), some babies may find it too slow as they get older, and you will need to buy higher-flow nipples separately. Also, the 4 oz size means you will need to buy the 9 oz set sooner than with the MAM or Tommee Tippee.
Natural latch feel
- Natural Response nipple mimics breastfeeding pace
- Anti-colic valve reduces tummy pain after feeding
- No-drip design prevents wasted milk
Slow flow rate
- 4 oz capacity is small — plan for an upgrade to 9 oz later
- Flow 2 may be too slow for older babies (buy separate nipples)
Best for breast: Moms who are breastfeeding but want dad to take a shift — the Natural Response nipple keeps baby drinking at their own pace.
Skip if fast: The small 4 oz size means you will need a second set of bigger bottles within a few months.
5. Tommee Tippee Natural Start Anti-Colic 9 oz BPA Free Baby Bottles, 6 Pack
See price on AmazonA 6-pack of leakproof bottles that transition easily between breast and bottle.
Tommee Tippee Natural Start bottles feature a soft silicone nipple that flexes and stretches like a breast, encouraging a natural latch. The anti-colic valve sits inside the nipple and reduces air intake. The bottle itself is 100% leakproof when assembled correctly — buyers report that even turned upside down, it does not drip. One parent who tested multiple brands (Medela, Avent, Dr. Brown’s, Spectra, Munchkin Latch) said the Tommee Tippee had the best latch and no leaks.
At 9 oz, this bottle matches the MAM in capacity, and the 6-pack gives you enough bottles for a full day of feeding without washing constantly. It also self-sterilizes in 3 minutes in the microwave. Compared to the Philips Avent at 4 oz, the Tommee Tippee holds 9 oz, making it a longer-lasting investment. Owners mention the measurement marks may rub off over time in the dishwasher, so hand washing the outside is recommended.
The catch is that the set comes with Level 1 nipples only — you cannot choose a faster flow. One buyer solved this by drilling a small hole in the nipple to increase the flow. You will need to buy separate Level 2 or 3 nipples for older babies.
Soft nipple shape
- 100% leakproof even upside down — no mess in the diaper bag
- 6-pack is great value; enough bottles for a full day
- Soft nipple mimics breast for easy transition
Leak risk twist
- Only Level 1 nipples included — buy faster flow separately
- Measurement marks may rub off in the dishwasher
Best for latch: Parents who want a massive set of leakproof bottles that work from day one — the 6-pack covers you for the whole day without constant washing.
Skip if leak: The Level 1 nipples only work for younger babies; you will need to purchase faster flow nipples for babies over 3 months.
6. Gulicola Natural Glass Baby Bottle for Breastfeeding Babies, 5 oz
$31.98as of Jul 5, 12:06 AMA borosilicate glass bottle that survives drops and keeps milk pure.
If you are avoiding plastic entirely, the Gulicola Natural Glass bottle is made from premium borosilicate glass — BPA-free, BPS-free, and phthalate-free. Customers note it has survived multiple drops on sink and slate tile floors without breaking or chipping. The ultra-soft nipple mimics the natural feel and movement of breastfeeding, and the anti-colic vents allow your baby to drink continuously without gasping for air. One customer observed the bottle helped improve a shallow latch in their breastfed baby.
At 5 oz, it holds the same as the Nanobebe but in glass, and it includes storage caps so you can pump directly into the bottle and store it in the fridge. The wide neck makes cleaning easy, and you can sterilize it in a warmer, microwave, sterilizer, or boiling water. Unlike the heavier weight of some glass bottles, this one is designed to be easy to hold.
The main trade-off is weight — even though it is sturdy, glass is heavier than plastic, so it is less ideal for a baby learning to hold their own bottle. Also, the set is only 2 bottles, so you may need to buy multiple packs to cover a full day.
Glass durability
- Borosilicate glass is toxin-free and survives drops
- Slow flow nipple is perfect for newborns with shallow latch
- Storage caps allow direct pumping and fridge storage
Heavy when full
- Heavier than plastic — baby cannot hold it alone early on
- Only 2 bottles in the pack — buy multiple sets for full day
Best for eco: Parents who want a glass bottle that actually survives drops and keeps milk free from any plastic leaching.
Skip if light: You need a lightweight bottle for a baby learning to self-feed — the Pigeon PPSU or Nanobebe are lighter.
7. Pigeon PPSU Nursing Baby Bottle Wide Neck, Anti-Colic, 8 oz
$35.99as of Jul 5, 12:06 AMA Japanese-designed bottle based on research into how babies suckle..
The Pigeon PPSU bottle is based on research into the 3 natural movements a baby does while feeding. The nipple is super soft and flexible, with a “Latch-on Line” that guides the baby into the correct latch for effective adsorption. This design makes it especially helpful for babies who struggle with shallow latch or reflux. Reviewers point out that their baby latched comfortably and that the slow-flow nipples reduced gas issues significantly.
The bottle is made from PPSU (polyethersulfone), a medical-grade plastic that is lightweight, durable, and heat-resistant enough to withstand sterilizing without degrading. One reviewer switched from Dr. Brown’s to these bottles and saw a clear improvement in their newborn’s reflux. The wide-neck design simplifies cleaning and filling — just 3 parts total. Unlike the Dr. Brown’s, there is no internal vent tube to scrub.
The downside is the price — this is the most expensive option on the list. Also, the nipple comes in M (medium, for 3m+), so if you need a 0m+ nipple, you will need to buy it separately. One user highlighted that there is insufficient room for 4 scoops of formula in 8 oz of water, requiring a two-step mixing process.
Wide neck ease
- Latch-on Line helps baby latch correctly for effective feeding
- Durable PPSU stays clean longer than regular plastic after sterilizing
- Only 3 parts — easy to clean and assemble
PPSU scratches
- Premium price — the most expensive on this list
- M (3m+) nipple included; 0m+ nipple sold separately
- Insufficient room for 4 scoops of formula in 8 oz water
Best for grip: Your baby has reflux or a shallow latch and you are willing to pay more for a research-backed nipple design and medical-grade PPSU.
Skip if glass: You need a budget-friendly option — the MAM or Tommee Tippee offer excellent anti-gas performance for less.
Understanding the Specs
Venting Systems
A venting system is the mechanism that stops air from mixing with the milk. The three main types are: a vented base (like MAM), where air flows through the bottom of the bottle; an internal vent system (like Dr. Brown’s), where a thin tube inside the bottle creates a vacuum-free environment; and a nipple vent (like Philips Avent or Nanobebe), where the anti-colic valve is built into the nipple itself. Base vents and internal vents are more effective but add parts to wash. Nipple vents are simpler but may let in slightly more air.
Nipple Flow Rate
Nipple flow rate determines how fast milk comes out. A slow flow (sometimes labeled “Level 1,” “Slow,” or “0m+”) is ideal for newborns so they do not gulp and swallow extra air. A medium flow (“Level 2,” “3m+”) works for older babies who can handle a faster pace. Using a flow rate that is too fast for your baby’s age is among the most common causes of gas and fussiness — the baby cannot swallow fast enough and takes in air. Most bottles on this list come with a slow flow nipple; some, like the Pigeon, come with a medium flow nipple (3m+) and require a separate purchase for a 0m+ nipple.
