If you're here, you're probably holding two baby bottles in one hand, your phone in the other, and wondering which overpriced piece of silicone or plastic will actually help your breastfed baby take a bottle without a full-on protest.
You've heard the names: Comotomo and Nanobebe. Both brands promise a "breast-like" experience. Both are Instagram-famous. And both will cost you more than £20 per bottle.
But are they actually that different? And more importantly—which one will your baby accept?
TIn this comparison guide, we'l be breaking down the real pros, cons, and the deal-breakers you need to know about before you invest in either bottle.
Bottom Line: Which Bottle Should You Choose?
- Choose Comotomo if: You want the softest, most squeezable bottle that's super easy to clean and your baby struggles with latch. Just be prepared for its narrow base making it prone to tipping.
- Choose Nanobebe if: You exclusively pump and want to preserve breast milk nutrients with faster, safer warming. It stacks well but requires their specific warming method for best results.
- Or consider HeartBabe: If you want Comotomo's soft, breast-like feel WITHOUT the tippy base, at comparable value (£28.02), the HeartBabe Silicone Bottle gives you the best of both worlds.
The Real Story Behind the Search: Why Parents Compare These Two
Most parents land on the "Comotomo vs. Nanobebe" debate for one specific reason: their breastfed baby is rejecting every other bottle on the market.
You've tried the basic Tommee Tippee. Maybe even Dr. Brown's with all those fiddly parts. Nothing worked.
So you Googled "best bottles for breastfed babies," and two names kept appearing: Comotomo (the squishy, soft silicone bottle that looks like a grenade) and Nanobebe (the weird, flat breast-shaped bottle that promises to warm milk faster).
Both bottles claim to reduce "nipple confusion" and help breastfed babies transition to bottles smoothly. The question is: do they deliver?[1]
What Makes a Bottle "Good" for Breastfed Babies?
Before we dive into the head-to-head, let's quickly cover what actually matters when choosing a bottle for a breastfed baby.
The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately the first 6 months, with continued breastfeeding alongside complementary foods for at least the first year or longer.[2]
But the reality? Many parents need to introduce a bottle—for work, childcare, or simply for a break.
🔑 Key Features for Breastfed Babies
Experts and experienced parents agree that the best bottles for breastfed babies should have:
- A wide, soft nipple that mimics the breast's shape and encourages a wide latch[3]
- Slow flow to prevent the baby from preferring the easier bottle over the breast
- Anti-colic venting to reduce gas and discomfort
- Easy to clean because you'll be doing this 8+ times a day
Both Comotomo and Nanobebe tick these boxes on paper. But how do they actually perform?
Comotomo: The Soft, Squeezable Silicone Favourite
🍼 Comotomo Baby Bottle Overview
Material: 100% medical-grade silicone
Sizes: 5oz (150ml) and 8oz (250ml)
Price: Around £18-22 per bottle (UK)
Parts: 3 simple parts (bottle, nipple, collar ring)
What Makes Comotomo Different?
The Comotomo bottle is famous for one thing: it's incredibly soft and squeezable. The entire bottle body is made from medical-grade silicone, which means it feels more like a breast than a hard plastic bottle.
The nipple is also ultra-wide and flat, designed to encourage babies to latch with a wide mouth—the same way they would at the breast.
Parents love that you can squeeze the bottle gently to mimic the natural "let-down" reflex of breastfeeding. This can be especially helpful for newborns who are still learning to suck efficiently.
✅ Comotomo Pros
- Super easy to clean: Wide mouth opening fits a regular sponge—no special brushes needed
- Soft, breast-like feel: Many babies who refuse other bottles accept Comotomo due to its squeezable silicone body
- Simple design: Only 3 parts, so assembly and cleaning are quick
- Dual anti-colic vents: Two vents in the nipple reduce air intake
- Dishwasher and microwave safe: Can be sterilized easily
❌ Comotomo Cons
- Tips over easily: The narrow base and soft body make it unstable, which is commonly reported by parents
- Nipple gets cloudy over time: After repeated washing, the nipple can look worn
- Hard to read measurements: The silicone is slightly opaque, making it difficult to see milk levels in dim light
- Can absorb odours: Silicone can retain smells if not washed immediately
- Doesn't fit all warmers: The wide, short shape doesn't fit in some narrow bottle warmers
⚠️ The Tipping Problem
This is Comotomo's biggest flaw commonly mentioned by parents. The egg-like shape and soft body make it top-heavy and prone to tipping. If you're clumsy or tired (so, every parent), this can be frustrating during night feeds.
Nanobebe: The Breast-Shaped Nutrient Protector
🍼 Nanobebe Baby Bottle Overview
Material: BPA-free plastic (breastmilk bottle) or silicone (Flexy bottle)
Sizes: 5oz (150ml) and 8oz (240ml)
Price: Around £20-25 per bottle (UK)
Parts: 4 parts (bottle body, snap-on base, nipple, collar ring)
What Makes Nanobebe Different?
Nanobebe's claim to fame is its unusual concave, breast-shaped design. The bottle is wide and flat, which spreads milk into a thin layer. This design allows milk to cool faster after pumping and warm faster before feeding—without damaging nutrients.[4]
Research shows that heating breast milk above body temperature (40°C/104°F) can degrade important immunological proteins and enzymes. Studies have found that temperatures above 50-55°C significantly reduce immunoglobulin A (IgA) and lactoferrin concentrations, which are critical for infant immune protection.[5] Nanobebe's design helps parents avoid this by warming milk more evenly in warm water, without the risk of hot spots or overheating.
The Nanobebe bottle also has a unique feature: it can attach directly to most breast pumps, so you can pump straight into the bottle and then store, warm, and feed from the same container. No milk transfers = less washing and no wasted drops.
✅ Nanobebe Pros
- Preserves breast milk nutrients: The flat design allows for more even warming at safe temperatures[6]
- Pumps directly into the bottle: Works with most major breast pumps with the right adapter
- Stacks easily: The flat design saves fridge and freezer space[7]
- Very stable base: Doesn't tip over like Comotomo
- Triple anti-colic vents: Reduces air intake during feeding
❌ Nanobebe Cons
- Awkward to hold while feeding: The flat, concave shape requires different positioning than traditional bottles
- Base can be fiddly to attach: The snap-on base requires proper sealing to prevent leaks
- Doesn't fit most bottle warmers: The unusual shape requires their specific warmer or warm water bowl[7]
- Takes up warmer space: If using an electric warmer designed for their bottle, the internal shape makes it difficult to use with other bottles
- More parts to clean: 4 parts compared to Comotomo's 3
⚠️ The Warming Method Matters
While Nanobebe bottles are designed to warm milk faster, they work best with their non-electric warming bowl or traditional warm water bath. Many electric warmers aren't designed to accommodate their unique shape, which can affect warming efficiency.

Which Bottle Actually Wins for Breastfed Babies?
Here's the truth: neither bottle is perfect. They both have significant trade-offs.
Choose Comotomo If:
- Your baby struggles with latch and needs the softest, most breast-like bottle available
- You value easy cleaning above all else

When Should You See a Doctor About Bottle Refusal?
While most bottle refusal is simply a matter of finding the right bottle and being patient, there are times when you should consult your pediatrician or a lactation consultant:
🚨 Seek Professional Help If:
- Your baby is losing weight or not gaining appropriately[8]
- Baby shows signs of tongue-tie or lip-tie (difficulty latching, clicking sounds while feeding)[3]
- Feeding sessions last longer than 45 minutes or baby seems constantly frustrated
- You notice blood in spit-up or persistent projectile vomiting
- Baby refuses all bottles for more than 24 hours and you need to return to work
- You're experiencing painful nursing or signs of mastitis

Additional Tips for Introducing Bottles to Breastfed Babies
The right bottle is only half the battle. Here are evidence-based strategies to help your breastfed baby accept a bottle:
Timing Matters
Introduce bottles between 3-6 weeks old—after breastfeeding is established but before strong preferences form.[2]
Let Someone Else Feed
Babies can smell milk on you. Have your partner or another caregiver offer the first bottles while you're in another room.
Get Temperature Right
Breast milk should be body temperature (37°C/98.6°F). The CDC recommends warming milk gently in warm water, never in a microwave, which can create hot spots and destroy nutrients.[9]
Pace the Feed
Hold baby more upright and pause frequently. This mimics breastfeeding pace and prevents bottle preference.[10]
The Limitations of These Bottles (What They Won't Fix)
Before you click "add to cart," it's important to have realistic expectations:
- No bottle eliminates colic entirely. While anti-colic vents help, some babies have colic due to digestive immaturity, not air intake.[11]
- Even "breast-like" bottles won't guarantee acceptance. Some babies simply prefer the real thing and will refuse bottles no matter what you try.
- Silicone bottles require immediate cleaning. If you leave milk residue, they can develop odours that are hard to remove.
- Price doesn't equal performance. A £25 bottle isn't necessarily better for your baby than a £10 bottle—it depends entirely on your baby's preferences.
What Other Parents Are Saying
We reviewed hundreds of real parent experiences with both bottles. Here's what consistently came up:
💬 Common Feedback on Comotomo:
"The tipping drives me insane, but it's the only bottle my daughter will take. I just always set it down very carefully now." – Sarah, mother of 4-month-old
"Best bottle for cleaning. I can fit my whole hand inside to scrub. Game changer for thrush prevention." – James, father of twins
💬 Common Feedback on Nanobebe:
"Love that I can pump directly into it, but warming it in my electric warmer is impossible. I use a bowl of warm water instead." – Rachel, exclusively pumping mum
"The snap-on base leaked twice and soaked the bed. Make sure it's really clicked in." – Tom, father of 3-month-old[12]
Final Verdict: Which Should You Buy?
If you're exclusively breastfeeding and just need an occasional bottle, start with Comotomo. It's the easiest to clean and many babies accept it. Just be mindful of the tipping issue.
If you're pumping regularly and want to preserve every drop of liquid gold, Nanobebe is worth the investment—especially if you use their warming method.
But if you want the best all-around solution that combines Comotomo's soft, breast-like feel with better stability and great value, the HeartBabe Silicone Bottle is your smartest choice.
Ultimately, the "best" bottle is the one your baby will actually drink from. Consider buying one of each to test, then stock up on whichever works. Many parents find they need 4-6 bottles in rotation to make life manageable.
