Silicone baby bottles feel different from plastic or glass on the very first feeding. The body gives slightly as your baby drinks, the surface stays soft against gums, and a drop off the highchair doesn’t end in broken glass.
The big reason parents switch is the breast-to-bottle transition. A soft, squeezable body paired with a dual-vent nipple (like the Comotomo Natural Feel) helps gas-prone babies latch without swallowing as much air.
Every bottle on this list is full silicone, not a plastic shell with a silicone nipple attached. We ranked all 10 on flow control, cleaning access, and how closely the nipple mimics nursing.
Capacities range from 5 oz for newborns up to 9 oz for older infants. The quick comparison chart below lines up all 10 picks so you can narrow your options before reading the full reviews.

4. Flipsi Natural Silicone Baby Bottle — Best for Easy Cleaning
Flipsi Natural Silicone Baby Bottle
Flipsi natural silicone baby bottle that turns inside out for quick cleaning and gives a vacuum effect to reduce bubbles.
Pros
- Flips inside out for rinse cleaning, no bottle brush needed
- CPSC safety-standard nipple, flow level 1 out of the box
- Flexible sides collapse as baby drinks, reducing air gulp
- Microwave, dishwasher, and steam sterilizer compatible
Cons
- Volume markings are based on US ounces, check before buying
- Hand wash the nipple to avoid warping in high-heat cycles
Flipsi’s natural silicone baby bottle solves the cleaning problem most baby bottles create by being flippable inside-out.
The wide silicone body turns inside-out for direct cleaning of every interior surface, no bottle brushes required, which makes the dishwasher-safe construction far more effective than bottles where milk residue hides in unreachable corners.
The bottle is BPA-free food-grade silicone and polypropylene, free from phthalates, latex, nitrosamines, lead, PVC, and PET.
The wide natural nipple shape mimics a breast for easier breast-to-bottle transition, and air can be squeezed out before feeding to reduce nipple confusion.
Flexible silicone walls collapse inward during feeding to minimize air intake, the anti-colic feature that makes the bottle worth the premium over standard plastic.
Flippable body takes practice to reassemble correctly after cleaning, so the first few washes feel awkward until the technique clicks. Hand wash the nipple to avoid warping in high-heat dishwasher cycles.
It ships with a level 1 nipple flow rate sized for newborn through 3 months. Additional flow rates for older babies are sold separately.
5. Olababy Gentle Bottle 2 Piece Coral Set — Best for Upright Feeding
Olababy Gentle Bottle 2 Piece Coral Set
Olababy Gentle Bottle 2-piece coral set with a side-angled nipple and dual venting system for smoother nursing-to-bottle transitions.
Pros
- Off-centered nipple lets baby feed in an upright position
- Dual-vent anti-colic system built into the collar
- Two-pack in coral, includes slow-flow newborn nipples
- Wide-neck mouth makes hand scrubbing straightforward
Cons
- Repeated sterilizing can slightly soften the nipple base
- Milk fat can leave a faint haze if not hand-scrubbed between feeds
Olababy’s Gentle Bottle 2-piece coral set targets the breastfeeding-to-bottle transition specifically.
The off-centered side-angled nipple mimics natural breast shape and feeding angle, which reduces bottle rejection in babies who have established breastfeeding habits and resist standard centered-nipple bottles.
Each 4-ounce bottle is made from food-grade silicone (BPA, PVC, and phthalate free) with smooth texture for easy gripping and a wide neck for easy cleaning.
The integrated dual-venting anticolic system limits air ingestion during feeding, the second feature that helps reduce gas and discomfort in newborns.
Off-center nipple position also keeps the nipple full of liquid during upright feeding, the position pediatricians recommend for reflux-prone babies.
The side-angled nipple takes adjustment for some babies who need a few feeds to figure out the new angle. Dual vent parts add extra pieces to wash after each feed, which adds time to the cleanup routine.
Two bottles in the set covers most one-baby households for a half day of feeds before the next wash cycle. When your baby starts self-feeding, silicone plates and silicone placemats make the highchair transition easier to clean up.
6. Nuby 2 Piece 360 Comfort Silicone Bottle — Best for Late-Stage Feeders
Nuby 2 Piece 360 Comfort Silicone Bottle
Nuby 2-piece 360 Comfort silicone bottle set with a weighted straw for every-angle sipping and a dual-vent valve.
Pros
- Weighted straw follows the liquid at any tilt, drains to the last drop
- 8 oz capacity with marks in both oz and mL
- Soft squeeze-base lets parents assist during a slow feed
- Two-pack for alternating while one is in the sterilizer
Cons
- Top-rack placement only to avoid deforming the teat
- Pastel colors dim gradually after repeated sterilizing
Nuby’s Comfort 360 Plus silicone bottle solves the position-flexibility problem with a weighted straw that follows the liquid inside the bottle no matter how the baby holds it.
Tilt the bottle, drink upside down, lay it sideways, and the straw stays at the bottom against the milk, the design that lets babies drink to the last drop without help.
The set ships as two 8-ounce bottles with slow-flow Soft Flex nipples that include built-in valves to reduce air ingestion. The silicone bottle base is squeezable, which lets parents gently assist feeding when babies are still building suction strength.
Graduated ounce and milliliter markings on the bottle simplify formula mixing without separate measuring cups. All parts are dishwasher safe, with boiling and steam sterilization options for deep cleaning.
Weighted straw adds extra pieces to wash after each use, which slows down the cleaning routine for families running through several bottles a day.
Straw design works better for older babies who have figured out straw mechanics than for newborns just learning suckling.
For babies who push back against traditional bottles, the straw alternative is worth the extra cleanup time.
7. Nanobebe Flexy Silicone Baby Bottle — Best for Gift Registries
Nanobebe Flexy Silicone Baby Bottle
Gray 2-pack of 5 oz Nanobebe Flexy anti-colic silicone bottles with a non-collapsing nipple and non-tip stable base.

- Easy-read volume scale printed along the silicone body

Our #7 pick is the Nanobebe Flexy Silicone Baby Bottle. Gray 2-pack of 5 oz Nanobebe Flexy anti-colic silicone bottles with a non-collapsing nipple and non-tip stable base.
A couple of things to know before you buy: 5 oz size may be outgrown by older infants, and silicone bottles feel softer than plastic and take getting used to.
If those limits do not block your use case, the 8.4/10 score reflects what we think this product delivers at its price point.
8. Nanobebe Flexy Silicone Baby Bottle — Best for Gift Registries

It also makes switching between breast and bottle easier.

9. Mason Silicone Baby Bottle — Best USA-Made
Mason Silicone Baby Bottle
Mason Bottle silicone baby bottle with a wide shoulder-less neck for easy cleaning and thick walls that help hold warmth.
Pros
- Made 100 percent in the USA, rare in silicone baby bottles
- Dual-valve FussFree anti-colic nipple reduces gas
- Shoulderless wide-neck design opens fully for brush-free cleaning
- Ships with medium-flow nipple, sized for 3-plus months
Cons
- Top-rack placement only to avoid deforming the teat
- Thinner than expected on budget models
Mason Bottle’s 8-ounce silicone baby bottle is made in the USA with a glass-free design that keeps plastic from touching baby’s milk entirely.
The thick silicone walls help hold milk warmth across the feed, and the wide shoulderless neck makes hand washing or top-rack dishwashing simple without needing a bottle brush.
The nipple is wide and breast-like, sized at medium flow for babies 3 months and older, with a dual-valve FussFree Ventilation system that reduces colic and gas during feeding.
The bottle is naturally BPA-free and BPS-free along with phthalate-free construction.
A plastic ring and cap secure the nipple to the silicone body. Mason Bottle is daycare-approved because the glass-free format eliminates breakage risk during care drop-off and pickup.
Wide mouth that makes cleaning easy also makes spills more likely when pouring formula in or out, so transfer carefully over a sink. Thicker walls mean the bottle warms more slowly in a bottle warmer than thin-walled alternatives.
For families specifically wanting USA-made non-glass bottles for daycare use, the format covers the niche.
10. Gaodear Silicone Squeeze Feeding Bottle — Best for Starting Solids
Gaodear Silicone Squeeze Feeding Bottle
Gaodear silicone squeeze feeding bottle with an attached spoon, built for semi-solid foods during travel and on-the-go feeding.
Pros
- Squeeze-feeder with attached spoon for purees and first foods
- Graduated barrel helps control portion sizes during weaning
- Sealing cap prevents diaper-bag leaks between feeds
- Includes a cleaning brush for the spoon holes
Cons
- Sterilize before first use to clear any packaging residue
- Volume markings are based on US ounces, check before buying
Gaodear’s silicone squeeze feeding bottle combines a 3-ounce silicone reservoir with a built-in dispenser spoon, sized for traveling parents feeding semi-solid foods like rice cereal, fruit puree, or vegetable mash.
The squeeze design pushes food directly through the spoon as the parent feeds, which removes the bowl-and-spoon assembly step that gets messy on the road.
Construction is food-grade PP and silicone, BPA-free per the manufacturer, and sterilize-safe through boiling water or top-rack dishwasher cycles.
A sealing cover prevents food leakage during transport in a diaper bag, and a dust cover keeps the spoon area clean between uses.
Volume markings on the side help with measured feedings of medicine or precise puree amounts. Suitable for rice cereal, fruit and vegetable purees, juice, and children’s medicine.
Squeeze feeding requires practice to control flow into baby’s mouth without overshooting, especially for newer parents adjusting to the format. The attached spoon is fixed and can’t be swapped for other shapes or larger sizes as the baby grows.
For travel and on-the-go feeding specifically, the format eliminates several pieces of feeding gear from the diaper bag.
Frequently Asked Questions
Are silicone baby bottles safer than plastic or glass?
Food-grade silicone bottles like the Comotomo and Olababy are marketed as free of BPA, BPS, PVC, and phthalates. They also cannot shatter like glass if dropped on a tile kitchen floor, which makes them a practical middle ground for parents who want glass-level purity without the breakage risk.
Do silicone baby bottles reduce colic and gas?
Several bottles on this list, including the Perry Mackin Anti-Colic and the Nanobebe Flexy, use internal venting systems that let air escape without mixing into the milk. This reduces the amount of air a baby swallows during feeding, which is the main trigger for colic pain and gas.
Can you sterilize silicone baby bottles in boiling water?
Yes, pure silicone bottles like the Comotomo and Boon NURSH can be boiled, run through a steam sterilizer, or tossed in the dishwasher on a hot cycle without warping.
The Mason Bottle sleeve is a popular pick for parents because the underlying mason jar glass is also fully sterilizable, so every part of the feeding setup is easy to clean.
How do silicone baby bottles handle the transition from breast to bottle?
Bottles with a soft, nursing-shaped body like the Comotomo and Nanobebe Flexy are designed to mimic the give and feel of a breast, which helps exclusively nursed babies accept a bottle without a strike.
The wide-base nipple shape encourages the same latch a baby uses at the breast and cuts down on nipple confusion.
What size silicone bottle should you start with for a newborn?
Most parents start with the smaller 4 to 5 ounce size for newborns because it matches the small volumes a baby takes in early weeks, then step up to the 8 ounce size around three to four months. The Comotomo bundle and Nanobebe two-pack both come in the smaller starter size.
Do silicone bottles stain or hold onto formula odors?
Silicone is less porous than plastic so it resists staining from formula and breast milk, but residue can still build up around nipple vents if bottles are not rinsed quickly after feeding. A quick hot water rinse right after the feed, followed by a regular wash with a bottle brush, keeps Comotomo and Olababy bottles looking clean for the long haul.
Why do silicone nipples sometimes collapse mid-feed, and how do I fix it?
Nipple collapse happens when air can’t re-enter the bottle fast enough, creating a vacuum that pulls the nipple flat.
The three most common fixes are loosening the collar a quarter turn, cleaning dried formula out of the vent disc, or stepping up to a faster-flow nipple stage that matches your baby’s age.
Final Thoughts
Comotomo earns the top slot because the wide-bulb shape and skin-soft silicone closely mimic the breast, which makes it the easiest bottle on the list for breastfed babies to accept. The wide opening also makes hand-washing fast on nights when the dishwasher is full.
For colicky babies, the Perry Mackin runner up uses a vented anti-colic system that reduces the air babies swallow during feeds. Less swallowed air usually means fewer late-night gas episodes, which is what matters at 3 AM.
The Boon NURSH is the value pick because the silicone pouch collapses as the baby drinks, mimicking the same pressure dynamics as breastfeeding without the price tag of premium anti-colic systems.
Pouches are also disposable for travel days when sterilizing on the road is impractical.
For busy parents balancing cost and quality, mix and match across these picks rather than committing to a full set of one brand. Silicone bottles age out fast as babies grow, so flexibility costs less than a six-pack purchase you outgrow.
