Comotomo Silicone Baby Bottles vs. MAM Easy Start Anti-Colic Bottles
Both are excellent anti-colic bottles with very different designs. Comotomo wins on breast-like feel and simplicity. MAM wins on self-sterilizing convenience and venting performance. Your baby's latch preference will likely be the deciding factor.
Comotomo and MAM are two of the most recommended bottles for breastfed babies and gassy babies, respectively. Comotomo's soft silicone body mimics the breast. MAM's self-sterilizing base and vented bottom cut down on air intake. Both reduce colic symptoms — they just approach the problem differently.

Two Popular Bottles — Very Different Approaches
Comotomo and MAM Easy Start Anti-Colic bottles sit near the top of every "best baby bottle" list, and both have loyal followings. But they solve different problems.
Comotomo was designed for breastfed babies. Its soft, squeezable silicone body and wide, breast-shaped nipple make the transition between breast and bottle as smooth as possible. The anti-colic venting is built into the nipple.
MAM Easy Start was designed to fight colic. Its vented base keeps air flowing into the bottle from the bottom, so it never mixes with the milk your baby drinks. It also self-sterilizes in the microwave — a feature that saves real time at 3 AM.
Both bottles work well. The right one depends on whether your top priority is breast-to-bottle transition or maximum colic relief.

| Feature | Comotomo Silicone | MAM Easy Start Anti-Colic | What It Means |
|---|---|---|---|
| Manufacturer | Comotomo Inc. | MAM Babyartikel GmbH | Comotomo is a US-based brand. MAM is an Austrian company with decades in the European baby market. |
| Bottle material | 100% medical-grade silicone | BPA-free polypropylene (plastic) | Silicone is more durable and chemical-free. Plastic is lighter and cheaper. Both are safe. |
| Anti-colic system | Dual anti-colic vents in the nipple | Vented base design (air enters bottom, stays separate from milk) | MAM's base venting is more effective at keeping air out of the milk. Comotomo's vents work well for mild gas. |
| Nipple shape | Wide, naturally shaped, breast-like | Wide, flat, SkinSoft silicone | Comotomo feels more like the breast. MAM's flat nipple is accepted by many babies but feels different. |
| Body feel | Soft, squeezable silicone (mimics breast) | Rigid plastic | Comotomo's squeezable body helps babies who want to knead while feeding, like they do at the breast. |
| Sterilization | Requires separate sterilizer or boiling | Self-sterilizing in microwave (3 minutes) | MAM wins on convenience. No extra equipment needed — just add water, microwave, done. |
| Cleaning | Wide neck, but soft body can trap residue | Disassembles into 3 wide-mouth pieces | MAM is easier to fully clean. Every piece opens wide. Comotomo's silicone body needs careful scrubbing. |
| Sizes available | 5 oz and 8 oz | 5 oz and 9 oz | Nearly identical size options. Both cover newborn through older infant stages. |
| Nipple flow rates | Slow, medium, fast (sold separately) | 0, 1, 2, 3, X (size-specific included) | MAM offers more flow rate options. Comotomo keeps it simple with three choices. |
| Breast pump compatible | No (non-standard thread) | No (non-standard thread) | Tie. Neither works directly with standard breast pump flanges. Both require milk transfer. |
The Anti-Colic Difference
Both bottles claim to reduce colic, but they use fundamentally different engineering to get there.
Comotomo places two small anti-colic vents directly in the nipple. As your baby drinks, air enters through these vents instead of creating a vacuum. This prevents the bottle from collapsing and reduces the amount of air mixed into the milk. It works — but the vents are small, and some parents report they can clog if not cleaned carefully.
MAM Easy Start uses a vented base design. Air enters from the bottom of the bottle, travels up through a channel, and replaces the milk volume without ever passing through the liquid. The result: your baby drinks milk with significantly less dissolved air.
In practice, MAM's base-venting system tends to be more effective for babies with serious gas or colic. Comotomo's nipple vents are sufficient for babies with mild fussiness. If your baby screams after every feed and pulls their legs up in pain, MAM is worth trying first.
Neither bottle is a guaranteed colic cure. Colic has multiple causes — air intake is just one of them. But reducing swallowed air is one of the few things you can actually control.
Material: Silicone vs. Plastic
This is where the two bottles differ most visibly.
Comotomo's body is 100% medical-grade silicone. It is soft, squeezable, and feels nothing like a traditional bottle. Babies who are used to the breast often accept it more readily because they can knead and compress it the way they do during nursing. Silicone does not leach chemicals when heated, does not stain easily, and does not absorb odors over time.
MAM's body is BPA-free polypropylene plastic. It is lightweight, rigid, and durable in the traditional sense. Polypropylene is considered safe for baby use and is the most common material in baby bottles worldwide. However, plastic bottles can stain from breast milk fats, absorb odors over time, and eventually become cloudy.
If material purity is your top concern, Comotomo's all-silicone construction is hard to beat. If you prefer a familiar, lightweight, affordable bottle, MAM's plastic is perfectly safe and functional.

Cleaning and Sterilization: MAM's Biggest Advantage
This is where MAM pulls ahead for many parents.
MAM bottles disassemble into three wide-mouth pieces — the base, the body, and the nipple/ring. Every piece opens wide enough to scrub easily. And the base doubles as a microwave sterilizer: add water, snap the pieces in, microwave for three minutes, and you are done. No separate sterilizer needed.
Comotomo bottles have a wide neck that makes it easy to reach inside with a brush. But the soft, squeezable silicone body can trap milk residue in folds, especially where the base meets the body. You need to be thorough. Sterilization requires a separate steam sterilizer or boiling water.
If you are washing bottles six times a day — and you will be — the ease of cleaning matters more than you think right now. MAM's design was clearly built with exhausted parents in mind.
| Product | Typical Price | Cost Per Bottle | Notes |
|---|---|---|---|
| Comotomo 5 oz (2-pack) | $24–$28 | ~$12–$14 | Includes slow-flow nipples |
| Comotomo 8 oz (2-pack) | $26–$30 | ~$13–$15 | Includes medium-flow nipples |
| MAM Easy Start 5 oz (3-pack) | $21–$27 | ~$7–$9 | Includes Size 1 nipples + self-sterilizing case |
| MAM Easy Start 9 oz (2-pack) | $16–$22 | ~$8–$11 | Includes Size 2 nipples + self-sterilizing case |
Price: MAM Is the Better Value
MAM bottles cost roughly 40–50% less than Comotomo bottles. A three-pack of MAM 5 oz bottles runs $21–$27. A two-pack of Comotomo 5 oz bottles costs $24–$28 — and you get one fewer bottle.
MAM also saves you money on sterilization equipment. Since each bottle self-sterilizes in the microwave, you do not need to buy a $30–$60 steam sterilizer separately.
That said, Comotomo's silicone body is significantly more durable than MAM's plastic. Silicone does not crack, cloud, stain, or retain odors the way plastic does. If you plan to reuse bottles for a second child, Comotomo may actually cost less per use over time.
For a single baby on a budget: MAM is the clear value winner. For families planning to reuse bottles across multiple children: Comotomo's durability closes the price gap.

- Your baby has significant colic, gas, or air-swallowing issues
- You want self-sterilizing convenience with no extra equipment

Where to Buy
If breast-to-bottle transition is your priority, the Comotomo Silicone Baby Bottles (~$13/bottle) are the gold standard for combo-feeding families. The soft silicone body and breast-shaped nipple make them the closest thing to nursing from a bottle. Worth the premium if nipple confusion is a concern.
If colic relief and easy cleaning matter most, the MAM Easy Start Anti-Colic Bottles (~$8/bottle) deliver strong vented performance at a lower price point. The self-sterilizing base is a genuine time-saver, and the wide disassembly makes cleaning painless.
Our honest advice: if you can, buy one pack of each and let your baby decide. Babies have strong preferences about nipple shape, and no amount of research can predict which one your baby will accept.
