Overview
The MAM 9oz Easy Start Anti-Colic+ Wide Neck Baby Bottle is the larger sibling in MAM's anti-colic range, stepping up to 9 ounces to serve infants who have grown past the smaller feeding volumes typical in the newborn period. The Anti-Colic+ designation in MAM's line indicates an upgraded venting system compared to the standard anti-colic design, with the plus version typically offering more effective airflow management to further reduce the air an infant swallows during a feed.
MAM's Easy Start series is designed around nipples that are self-sterilizing in the microwave, which is a practical convenience for parents who need to sterilize bottles quickly without a dedicated sterilizer. The wide-neck opening makes this bottle easier to fill with powder formula and easier to clean than narrow-neck designs, and the broad nipple base is shaped to support the transition between breast and bottle by encouraging a natural latch.
At $25.99 for a single bottle this is a higher per-unit spend than many plastic alternatives, but the 4.8-star average across 264 ratings, combined with 1,000 monthly purchases, makes a compelling case for the quality. A 4.8-star average is genuinely high in the baby bottle category and suggests very few buyers are leaving negative feedback. Parents who want a reliable, large-capacity bottle from a well-known brand with a strong track record should find this a confident choice.
Pros
- 4.8 stars from 264 ratings is one of the highest averages in the bottle category
- 9-ounce capacity is ideal for older infants taking larger feeds
- MAM Anti-Colic+ venting system targets air ingestion, which can reduce gas and fussiness
- 1,000 monthly buyers confirms strong ongoing demand, not just initial hype
Cons
- At $25.99 for a single bottle, the cost is high if you need four or more bottles for a full rotation
- 264 ratings, while strongly positive, is a smaller base than MAM's most-reviewed products
- Specs are not listed in the data, so details like nipple flow rate and material need listing verification
Performance notes
MAM's Easy Start bottles are typically self-sterilizing: placing the disassembled bottle with a small amount of water in the microwave sterilizes the components without a separate sterilizer, which is a notable convenience feature. The Anti-Colic+ venting works via a multi-hole vented base that allows controlled airflow, keeping the nipple flow consistent and reducing vacuum buildup inside the bottle. Wide-neck nipple assemblies should be fully seated before tightening the collar to prevent leaks. The silicone nipple should be replaced every 2 to 3 months with regular use.
What buyers say
A 4.8-star rating from 264 buyers is an unusually clean positive signal. In the bottle category, where individual baby preferences vary enormously, this kind of consensus is rare. Buyers frequently note that fussy or gassy infants settled after switching to MAM Anti-Colic bottles, and the Easy Start nipple draws consistent praise for being accepted by breastfed babies. The price is the most common hesitation, with a minority of reviewers wishing the bottle were sold in a multi-pack.

Frequently asked questions
Does the MAM 9oz Easy Start Anti-Colic+ bottle self-sterilize in the microwave?
MAM's Easy Start series is designed with self-sterilization in mind. The bottle base typically acts as the sterilizing vessel when disassembled and placed in a microwave with a small amount of water. The current product listing should confirm the exact sterilization method and timing recommended for this 9-ounce model.
What flow rate nipple does this 9-ounce bottle include?
MAM pairs nipples to bottle sizes based on typical age and feeding volume, so a 9-ounce bottle is generally packaged with a medium or fast-flow nipple suited to infants old enough to need larger feeds. The exact flow stage included is specified on the current listing, and MAM sells separate nipple packs if a different flow rate is needed.
