Context, not marks against it, and our read of the data, not a lab test.

Overview

With 20,472 ratings and a 4.8-star average, the MAM Easy Start Anti-Colic+ is one of the standout products in the baby bottle category. Very few baby products accumulate this volume of reviews while maintaining a near-perfect rating, which is a strong signal that the anti-colic venting system delivers on its promise for the vast majority of parents. The wide-neck design makes filling and cleaning easier than narrow-neck alternatives, and it also typically supports a nipple shape that more closely resembles breastfeeding.

The 9-ounce capacity is versatile enough to carry newborn feeds of 2 to 4 ounces early on and scale up as the infant grows into 6 to 8 ounce feeds over the first few months. The 2-pack format at $12.96, roughly $6.48 per bottle, makes this one of the more accessible entry points into the MAM feeding system. MAM's anti-colic venting works through a bottom-vent base that draws air away from the liquid, reducing the air ingestion that causes gassy discomfort.

With 1,000 units bought last month and an enormous review base, this bottle has clearly moved beyond early-adopter enthusiasm into sustained mainstream use. It represents a sensible default choice for parents who want a well-vetted anti-colic wide-neck bottle without paying premium prices.

Pros

  • 4.8 stars from 20,472 reviews is an exceptional validation record for any baby product
  • Anti-colic vented bottom base reduces air ingestion during feeds
  • Wide-neck design simplifies filling, cleaning, and nipple assembly
  • 9-ounce capacity grows with the infant from newborn to older baby stages
  • 2-pack at $12.96 delivers strong value per bottle

Cons

  • Wide-neck format means MAM nipples are not interchangeable with narrow-neck bottle brands
  • Bottom-vent anti-colic system adds one more part to wash and reassemble
  • Some infants with no colic issues will not need the venting feature and could do with a simpler bottle

Performance notes

Based on the 20,472-owner review record and MAM's documented venting design, the Easy Start Anti-Colic+ bottom-vent system channels air away from the milk, which owners widely report reduces gassy behavior and discomfort after feeds. The wide-neck opening means a bottle brush reaches the interior easily, and most MAM bottles can be sterilized in a microwave sterilizer or on the top rack of a dishwasher. The vented base needs to be correctly seated when assembling the bottle to maintain its anti-colic function, a step owners should confirm during first use.

What buyers say

The combination of 4.8 stars and 20,472 reviews is rarely seen in the baby feeding category, and it reflects genuinely broad owner satisfaction rather than a curated sample. Parents across a wide range of infant feeding situations appear to find this bottle effective, with the anti-colic venting system receiving consistent praise. The ongoing monthly purchase volume of 1,000 units confirms the bottle has earned long-term trust, not just initial curiosity.

Frequently asked questions

Does the MAM Easy Start Anti-Colic+ work for breastfed babies?

The wide-neck nipple shape on MAM Easy Start bottles is designed to mimic breast tissue contour, which many parents find helps breastfed babies accept the bottle without significant nipple confusion. Results vary by infant, but the wide-neck design is a common recommendation for combined breast and bottle feeding. Introducing the bottle when the baby is calm and slightly hungry rather than very hungry tends to help with acceptance.

How do I assemble the anti-colic vented bottom correctly?

The MAM Easy Start Anti-Colic+ uses a bottom-vent base that must be seated flush and locked before feeding. The vent draws air through a valve at the base rather than through the nipple, keeping air out of the liquid. Checking that the base is correctly positioned before every feed is important for the anti-colic function to work as intended.
