Tommee Tippee Natural Start Anti-Colic vs. Comotomo Silicone Baby Bottles

Both are well-loved bottles with strong anti-colic features. Comotomo wins on breastfeeding transition and squeezable silicone feel. Tommee Tippee wins on price, anti-colic venting, and wider availability. Your baby's preference will be the deciding factor.

These two bottles take very different design approaches. Tommee Tippee uses a polypropylene body with a built-in anti-colic valve. Comotomo uses a fully squeezable medical-grade silicone body that mimics the feel of skin. Both aim to reduce gas and make bottle-feeding easier — but they get there in different ways.

Two Popular Bottles, Two Very Different Approaches

Tommee Tippee Natural Start Anti-Colic and Comotomo Silicone Baby Bottles are two of the most recommended bottles by parents and pediatric feeding specialists. They show up on nearly every "best baby bottles" list — but they solve the bottle-feeding problem in fundamentally different ways.

Tommee Tippee takes the traditional approach: a rigid polypropylene body with a well-engineered anti-colic valve built into the nipple assembly. It's affordable, widely available, and works well for most babies.

Comotomo threw out the traditional bottle design entirely. Its body is made of soft, squeezable medical-grade silicone that feels more like skin than plastic. The idea is to replicate the breast-feeding experience as closely as possible — which is why lactation consultants often recommend it for babies who resist the switch from breast to bottle.

Both are excellent bottles. The right one depends on your baby's feeding history, your budget, and — most honestly — which one your baby decides to accept.

The Material Difference: Plastic vs. Silicone

The most obvious difference between these two bottles is what they're made of, and it affects everything from feel to cleaning to durability.

Tommee Tippee Natural Start uses BPA-free polypropylene — the same safe, lightweight plastic used in most baby bottles. It's rigid, easy to grip, and won't change shape over time. The downside: like all plastic bottles, it can stain with breast milk or formula and may develop micro-scratches that harbor bacteria. Plastic bottles should be replaced every 4–6 months.

Comotomo uses medical-grade silicone for the entire bottle body. You can squeeze it, and it bounces back. This soft, skin-like texture is the main selling point — babies who are used to the breast often accept it more readily because it doesn't feel like a hard, foreign object in their mouth. Silicone doesn't stain, doesn't absorb odors, and lasts significantly longer than plastic. It's also naturally heat-resistant and won't leach chemicals at any temperature.

The trade-off: silicone costs more. You're paying roughly double per bottle compared to Tommee Tippee.

Anti-Colic Features: Different Venting, Same Goal

Both bottles are designed to reduce the air your baby swallows during feeding — the primary cause of gas, fussiness, and spit-up.

Tommee Tippee's anti-colic valve sits at the base of the nipple and works by channeling air back into the bottle rather than into your baby's stomach. It's a separate piece that you insert during assembly. In testing and parent reviews, this valve is consistently praised as one of the more effective anti-colic systems on the market. The downside: it's one more part to wash, and if you forget to insert it, the bottle won't vent properly.

Comotomo's dual vents are built into the top of the nipple itself. They allow air to flow into the bottle as your baby drinks, preventing the vacuum effect that causes nipple collapse and air swallowing. The system is simpler — no extra parts — but some parents find it slightly less effective at reducing gas compared to a dedicated valve system.

If your baby has significant gas or colic symptoms, Tommee Tippee's dedicated valve may give you a slight edge. For mild gas, both bottles perform well.

Breast-to-Bottle Transition: Where Comotomo Shines

If you're breastfeeding and introducing a bottle — whether for daycare, a partner's turn at night feeds, or pumped milk — the transition can be rocky. Many breastfed babies reject bottles outright.

This is where Comotomo has a genuine advantage. The combination of a wide, naturally shaped nipple and a soft, squeezable body creates a feeding experience that feels closer to the breast. Lactation consultants frequently recommend Comotomo as a first-try bottle for breast-refusers.

Tommee Tippee's breast-shaped nipple also works well for many babies, and the brand markets it heavily as a breastfeeding-compatible bottle. But the rigid plastic body is a giveaway — babies can tell the difference. For babies who are mildly resistant, Tommee Tippee may be enough. For babies who are strongly breast-preferring, Comotomo is worth the extra cost.

That said, every baby is different. Some breastfed babies take a Tommee Tippee on the first try. Some refuse a Comotomo. You won't know until you try — which is why we recommend buying one of each before committing to a full set.

Prices as of March 2026. Retailer sales, registry discounts, and bundle deals can reduce costs. Replacement nipples cost $5–$8 per pack for both brands.

Price: A Real Difference This Time

Unlike diapers, where brands cost within pennies of each other, there is a meaningful price gap between these two bottles.

Tommee Tippee Natural Start bottles cost roughly $5–$8 per bottle depending on size and pack. A full set of six bottles runs about $35–$50.

Comotomo bottles cost roughly $11–$15 per bottle. A full set of six runs about $65–$90.

That's nearly double. If your baby takes a Tommee Tippee happily, there's no reason to spend more. If your baby refuses everything except Comotomo, the extra $30–$40 for a full set is money well spent — you'll spend more than that on bottles your baby rejects if you keep trying cheaper options.

Other ways to save:

  • Start with one or two bottles before buying a full set
  • Check your baby registry — bottles are a popular gift item
  • Buy replacement nipples, not new bottles — nipples wear out every 2–3 months, but Comotomo bodies last over a year
  • Watch for bundle deals on Amazon and Target

Choose Tommee Tippee Natural Start If

  • Budget matters — you need multiple bottles without spending a fortune
  • Your baby has gas or colic symptoms and you want a dedicated anti-colic valve
  • You prefer a lightweight, rigid bottle that's easy to hold
  • You want the widest selection of nipple flow rates
  • Your baby already takes a bottle without fuss and you don't need the skin-like feel

Choose Comotomo If

  • Your breastfed baby is refusing rigid bottles
  • You want a bottle that feels soft and skin-like to help with breast-to-bottle transition
  • Easy cleaning is a top priority — you hate bottle brushes
  • You prefer fewer parts to wash and reassemble
  • You want a silicone body that won't stain, retain odors, or degrade over time
  • You're willing to pay more per bottle for a premium feel and design

Where to Buy

If you want a reliable, affordable bottle with strong anti-colic performance, the Tommee Tippee Natural Start Anti-Colic (~$6–$8/bottle in multi-packs) is a solid choice that works well for most babies. The anti-colic valve is one of the best on the market, and the breast-shaped nipple helps with latch. Widely available at Target, Walmart, and Amazon.

If you're transitioning a breastfed baby to a bottle or want the softest, most breast-like bottle available, the Comotomo Silicone Baby Bottles (~$12–$15/bottle) are worth the investment. The squeezable silicone body, wide nipple, and easy-clean design make them a favorite of lactation consultants and parents of bottle-resistant babies.

Our honest advice: buy one of each and let your baby decide. The best bottle is the one your baby will actually drink from.

The Bottom Line

Tommee Tippee Natural Start and Comotomo take very different approaches to the same problem — getting milk into your baby comfortably and without excess air.

Comotomo wins on breast-to-bottle transition, squeezable silicone feel, ease of cleaning, and fewer parts. It's the bottle lactation consultants reach for when a breastfed baby refuses rigid bottles.

Tommee Tippee Natural Start wins on price, anti-colic valve effectiveness, nipple flow rate options, and availability. It's the workhorse bottle that delivers great performance without the premium price tag.

For most families who aren't dealing with breast refusal, Tommee Tippee is the better value. For families struggling with the breast-to-bottle switch, Comotomo is the bottle to try first.

If you're tracking feedings — which is especially useful in the first few months to make sure your baby is eating enough — tinylog makes it simple to log bottles, nursing sessions, and pumping output.
