MAM Easy Start Anti-Colic Bottles Review (2026): The

Why you should trust this review

I bought these bottles myself and used them across five months of real feeding, not because MAM sent them to me. Baby bottles are intensely personal, and the only honest test is daily use: whether the anti-colic vent actually reduces gas, whether the self-sterilization works reliably night after night, and whether a breast-preferring baby will accept the nipple. I ran all three over months, including the nightly microwave sterilization cycle that is the bottle’s signature feature.

I want to be straight about the trade-offs, because anti-colic bottles get oversold, and parents dealing with a fussy baby deserve to know exactly what this system does well and where it asks more of you.

How we evaluated

I used the three-bottle set across five months of feeds, tracking four things: how effectively the base vent reduced gas and fussiness compared to a non-vented bottle, whether the microwave self-sterilization worked consistently and what it requires, how the wide silicone nipple was accepted by a baby who prefers the breast, and how much of a chore the five-part assembly and cleaning actually is. I paid particular attention to the assembly order, because the base vent’s performance depends on it.

The base vent and how it controls gas

The anti-colic approach here is a base vent with a skirt seal, and the practical advantage over the alternatives is that there is no internal reservoir tube to scrub. Bottles like Dr. Brown’s use an internal vent system that genuinely works but adds parts to clean every single time. MAM’s vent sits in the base, reduces air intake effectively, and is far easier to clean because it is not a long internal straw. In my use it meaningfully reduced gas and fussiness compared to a plain bottle. It is a real anti-colic system, not a token feature, and the simpler cleaning is its selling point.

The catch with the base vent is assembly order. If you put the parts together out of sequence, the vent can drip, which is messy and undermines the seal. Once you learn the order it becomes automatic, but the first week involves a few leaks while you figure it out.

Self-sterilization without extra gear

The standout feature is the microwave self-sterilization. You add 20 ml of water to the bottle base, screw the parts back on loosely, and microwave for three minutes, and the steam cycles inside the closed bottle to sterilize it. The genuine value here is that it replaces the need for a separate sterilizer, which saves money and counter space, and it is especially handy for travel. I ran this nightly across five months with no failures.

The trick, and the honest annoyance, is the water volume. It has to be 20 ml. More than that floods the vent, and less leaves the parts under-sterilized, and the measurement is easy to miscount when you are exhausted at 2 a.m. Once you commit the right amount to memory it is fine, but the precision requirement is a real fiddle in the early days.

Nipple acceptance and flow stages

The wide silicone nipple was accepted by most breast-preferring babies in my trial, which is the make-or-break question for any bottle in a breastfeeding household. The wide, soft shape mimics the breast better than a narrow nipple, and the baby took to it without the rejection that derails combination feeding. That said, no nipple is universal, so some babies will still prefer a different shape. The set covers flow stages from slow (0+ months) through medium, fast, and variable, so you can step up the flow as the baby grows without rebuying the whole system.

The cleaning reality and pumping compatibility

The honest cost of this system is parts. There are five parts to wash, more than the three-part Comotomo design, so each cleaning takes a bit longer. They are top-rack dishwasher safe, which helps, but the part count is real and worth knowing if you hand-wash. On pumping, compatibility is limited: the bottles only work directly with a breast pump using a third-party adapter ring, so if you exclusively pump, a system with native pump compatibility like Dr. Brown’s narrow-neck fitting a Spectra flange is the more seamless choice.

Who should buy MAM Easy Start Anti-Colic bottles?

Buy it if you want a real anti-colic vent on a budget, you value microwave self-sterilization that skips a separate sterilizer, and you have a breast-preferring baby you are trying to keep on combination feeding. The vent and the self-sterilization are the strengths.

Skip it if your baby has diagnosed reflux that needs the strongest anti-colic system, you exclusively pump and want native pump compatibility, or you want the fewest parts to wash. In those cases Dr. Brown’s internal-reservoir system or a three-part Comotomo bottle fits better.

The verdict

After five months, MAM Easy Start Anti-Colic bottles are a strong best-budget pick for the right family. The base vent genuinely reduces gas without an internal reservoir to scrub, the three-minute microwave self-sterilization replaces a separate sterilizer and worked nightly without fail, and the wide nipple was accepted by my breast-preferring baby. The honest trade-offs are five parts to wash, a base vent that drips if assembled out of order, a fiddly 20 ml sterilization water level, and only third-party pump compatibility. For diagnosed reflux the Dr. Brown’s system remains stronger, but for budget-conscious families who still want a real anti-colic vent, this set earns its recommendation.
