Overview
MAM's Easy Active bottle addresses two common parent frustrations at once: baby gas and the chore of sterilizing bottles. The anti-colic vented base is designed to regulate air flow into the bottle, allowing babies to feed with less air ingestion and, in theory, less gas-related fussiness afterward. The 325.27 ml (approximately 11 oz) capacity gives enough room for the larger feeds typical of babies 4 months and up.
The self-sterilizing feature means you add a small amount of water to the base, place the assembled bottle in the microwave, and sterilize without buying a separate electric sterilizer. For families who do not want to invest in a stand-alone sterilizer, or who travel frequently, this is a practical advantage over bottles that require an external unit.
At $10.45 for a 2-pack, the per-bottle cost is under $5.25, which is competitive for an anti-colic bottle with sterilizer functionality built in. The 4.6-star average from 9,133 ratings and 900 monthly purchases place this among the most actively purchased anti-colic bottles in its price range. MAM uses a wide nipple collar and a distinctive silicone nipple shape that many parents report their babies accept quickly, though individual baby preferences always vary.
Pros
- Anti-colic vented base designed to reduce air intake and gas discomfort
- Self-sterilizing in the microwave removes the need for a separate sterilizer
- 4.6 stars from 9,133 reviews is a very strong signal of consistent satisfaction
- 325 ml capacity suits the larger feeding volumes of babies 4 months and older
Cons
- Designed for 4+ months, so not the right choice for newborns
- Microwave self-sterilizing requires access to a microwave and careful water measurement
- More parts than a simple two-piece bottle due to the vented base assembly

Performance notes
Owner reviews focus heavily on the anti-colic venting base and the self-sterilizing microwave feature. Parents of gassy babies frequently credit the vented base with reducing post-feed discomfort, though results vary between individual babies. The self-sterilizing cycle is consistently described as fast and convenient. The wide MAM nipple is noted as well-accepted by babies who alternate between breast and bottle. Leaking is rarely mentioned as a frequent issue at this rating level, though proper assembly of the vented base is important to maintain a good seal.
What buyers say
Nine thousand one hundred thirty-three ratings averaging 4.6 stars places the MAM Easy Active among the most robustly reviewed anti-colic bottles. The 900 monthly purchase rate shows it is a continuous staple choice, not a product that peaked and faded. Positive reviews consistently highlight the self-sterilizing base as a genuine convenience differentiator. Critical reviews, which are sparse, most often mention the assembly of the vented base taking a little practice to master.

Frequently asked questions
How does the MAM Easy Active anti-colic venting system work?
The MAM Easy Active bottle uses a vented base with small openings that allow air to enter the bottle from the bottom as the baby drinks. This replaces the air that would otherwise enter through the nipple, reducing the amount of air the baby swallows during a feed. Less swallowed air typically means less gas buildup and a more comfortable baby after feeding.
How do you self-sterilize the MAM bottle in the microwave?
Add a small amount of water (typically around 20 ml) to the base of the disassembled bottle, reassemble it loosely so steam can circulate, and microwave for the time specified on the packaging, usually around 3 minutes at full power. The steam generated inside sterilizes the bottle parts. Always allow the bottle to cool before handling and feeding. Check the MAM instruction leaflet for your specific wattage guidance.
