Why silicone?

Compared with plastic bottles, glass bottles, or stainless steel bottles, there are many unique benefits to choosing silicone for your baby’s bottles.

• Natural feeding experience

Silicone is soft, squishy, and easy to grip. Out of all bottle materials, silicone most closely resembles a mom’s breast, making silicone feeding bottles ideal for switching between breast and bottle. Nonetheless, even exclusively bottle-fed babies are sure to appreciate the soothing texture of silicone.

• Stable at extreme temperatures

Silicone has a wide temperature range tolerance. It can be boiled, microwaved, and frozen without any effect on its structure. Silicone bottles can be safely cleaned in the dishwasher.

• Hygienic

Silicone resists scratches that may trap harmful bacteria and is easily sanitized by boiling, keeping your breast milk or formula safe from contamination with pathogens.

• Lightweight

Silicone feeding bottles are lightweight, making them easy to hold even for the tiniest hands and carry in a diaper bag without weighing you down.

• Shatterproof

Glass can shatter, stainless steel can dent. Plastic and silicone bottles are the only feeding bottles that are virtually indestructible.

• Safer than plastic

Compared with plastic baby bottles, silicone is far more stable. Silicone is more resistant to chemical leaching and won’t shed microparticles in baby’s milk.

Drawbacks of silicone

Many new parents are drawn to silicone simply based on the increasing popularity of this material. When they start using the bottles, however, the reality sets in. Here are a few disadvantages of silicone bottles to expect if you choose silicone over other materials:

Silicone is slow to warm up. Silicone transfers heat at a much slower rate than all other bottle materials, so if you warm your baby’s milk, know that a silicone bottle will take longer to warm up no matter the method used. If your baby strongly prefers warm milk, this may not be the best bottle for you or at least not your favorite bottle, but there are shortcuts to help you manage your routine – if you’re using powdered baby formula, it’s best to preheat the water; for a liquid formula, re-heating formula milk, or warming up expressed breast milk, the fastest solution is to warm up the milk in a separate container and transfer into the bottle once it’s ready.

Stains and odors. Another issue you may face with silicone feeding bottles is that silicone is prone to staining and tends to attracts odors. (Scroll down for tips on how to keep your silicone bottles clean!)

Hard-to-read volume scale. All silicone baby bottle reviews combined clearly indicate frustration over how difficult it can be to read the measurements on silicone bottles since the lines and numbers are just imprinted into the silicone and therefore translucent. (On the plus side, there is no risk of lead paint like there is with glass bottles!)

Silicone is soft. Perhaps too soft? Situations where you might not appreciate the extreme malleability of silicone include when a baby likes to hold the bottle and squeezes the soft silicone material too harshly. This can increase the flow of milk into baby’s mouth and put your baby at risk of choking, or there could be leakage at the neck of the bottle. Additionally, because silicone bottles are so soft and grippy, they don’t slide into the diaper bag as easily as other bottle types.

Best silicone baby bottles

There are several silicone bottles on the market today that vary in price, design, and features. Below is a selection of the best silicone baby bottles that are safe for babies and parent-approved.

FYI: Silicone bottles are marketed as a plastic-free baby bottle alternative, but some have plastic interior components, so be sure to read the review for each bottle carefully if avoiding plastic is a top priority for you in bottle feeding.

Boon NURSH Silicone Baby Bottles

Buy: Amazon
Cost: $8-$9 per bottle on average
Key features: Air-free feeding, no plastic parts inside the bottle

Boon NURSH bottles are one of the best-rated silicone baby bottles on the market that differ from most other silicone feeding bottles. The body of the bottle isn’t just silicone – it consists of a hard plastic shell with a reusable inner silicone pouch.

The bottles are available in 4 oz and 8 oz and a variety of colors. The 4 oz bottle comes with a Stage 1 silicone nipple, and the 8 oz bottle has a Stage 2 nipple. There are 3 flow rates total.

Pros:

• Boon NURSH silicone bottles are designed to help prevent colic without the need to assemble a multi-piece anti-colic system. The reusable silicone pouch inside the bottle collapses as baby drinks, which cuts back on the amount of ingested air.

• Although the shell is plastic and so is the collar, the silicone liner seals with the collar in a way that baby’s milk doesn’t flow through any of the plastic parts.

• This is a 5-piece bottle that has that one extra piece due to the exterior plastic shell, but the plastic cover doesn’t necessarily have to be impeccably clean for each new bottle.

• A silicone nipple shaped like breast promotes natural latch. (FYI: The nipple is a bit on the firm side compared with many other baby bottles that have very soft and flexible nipples, though it’s not stiff enough to cause rejection by babies who are both breastfed and bottle fed.)

• The bottle is easy to assemble and has a wide neck, making it easy to fill and clean (wash by hand or in the dishwasher).

Cons:

• I’s important to fit the silicone pouch correctly on the rim of the outer plastic shell, otherwise the bottle may leak.

• The plastic cover adds a little bulk, and the cap is quite large. Overall, this is a somewhat bulky bottle to stow in a diaper bag, on the other hand it slides in easily thanks to the hard plastic shell.

• On the lighter-colored bottles the volume scale can be hard to read.

• The nipple flow is on the slow side for all flow rates.

• The silicone grade isn’t disclosed by the manufacturer. The only detail provided is 100% silicone. (Food and medical grade silicone is food-safe, but lower quality silicones may not be.)

Nanobébé Flexy Silicone Baby Bottles

Buy: Amazon
Cost: $8-9 per bottle on average
Key features: Advanced venting system, no plastic parts inside the bottle

Nanobébé is another top-rated silicone feeding bottle that’s comparable in price with Boon NERSH (above). Unlike Boon NERSH, this is a straight-up silicone bottle (made with food grade silicone).

Nanobébé bottles are available in 5 oz and 9 oz and 4 colors. Both sizes come with slow flow silicone nipples (#1), but 5 different flow rates in total are available for purchase.

Pros:

• A soft breast-like nipple with a unique 3-vent anti-colic design helps transition babies between breast and bottle and reduces fussiness and gas.

• The bottle consists of 5 pieces total (including the cap). The neck of the bottle is made up of 2 plastic parts (collar + rim), but baby’s milk doesn’t come in contact with these parts. (FYI: Make sure to separate the plastic rim for cleaning to prevent mold growth in the grooves underneath.)

• While the 2-piece collar adds 1 extra component compared with a standard bottle, the bottles are very easy to assemble and take apart, and all parts are dishwasher safe.

• Nanobébé silicone bottles have a unique shape and a wide stable base, so you don’t have to worry about them tipping over easily. And, with a wide neck, it’s easy to scoop formula in and wash by hand.

Cons:

• Some parents don’t love the nipples – either because the included slow-flow nipple can flow too fast for the youngest babies (NOTE: Preemie nipples are available for purchase for the earliest stages), or because the nipple is on the small side since the nipple base is partially covered by the plastic collar, leaving less room for baby to latch on.

• There is an added cost for nipples with other flow rates since both bottle sizes come with a Stage 1 nipple.

• The measurement lines are difficult to read, and the cap can be hard to snap on and tends to pop off.

• Due to the contoured wide base it can be difficult to find a bottle warmer that will accommodate the bottle.

• Additionally, the walls of the bottle are asymmetrical, leaving the bottle leaning slightly to one side, so you can’t read the levels correctly unless the bottle is placed on a flat surface.

Comotomo Baby Bottle

Buy: Amazon
Cost: $14 per bottle on average
Key features: Created to mimic breastfeeding, easy cleaning

The Comotomo baby bottle is probably the most well-known silicone baby bottle currently on the market. The bottle was designed for an easy transition between breast and bottle to help avoid bottle rejection and nipple confusion. Another key focus was to make the bottle easy to clean even if you wash your bottles by hand.

Comotomo bottles are available in 5 oz and 8 oz, and 2 colors. The 5 oz bottle comes with a slow flow silicone nipple, and the 8 oz bottle comes with a medium flow rate. 4 flow rates in total are available for purchase. (NOTE: The 5 oz bottle has a different, more rounded shape.)

Pros:

• Comotomo bottles have a simple design with only 4 parts total (including the cap). The less parts, the easier it is to assemble the bottle for feeding and take apart for cleaning.

• A wide-neck design makes it easy to fill and clean the bottles. (Plus the bottles are, of course, dishwasher-safe as well.)

• The nipple features dual anti-colic vents to help reduce colic.

• For what it’s worth, combination-fed babies seem to take to the bottle well.

Cons:

• Although a strong selling point of this bottle is that it’s made of silicone (food grade) which is considered safer for baby than a plastic bottle, there is an embedded internal plastic component at the neck of the bottle where the collar screws onto.

• Some reviewers mention mold growing in the grooves where the internal plastic component meets with the silicone, so do make sure to give the bottles a good clean and let them dry thoroughly.

• The top of the bottle is wider than the bottom, which makes the bottle prone to getting knocked over. The 8 oz bottle is not as rounded as the 5 oz bottle, but if you go with the larger bottle for a younger baby for practical reasons, do keep in mind that it comes with a medium flow nipple which might be too advanced for your baby and you’d need to purchase the slow-flow nipples separately.

• The soft squeezable nature of silicone around the neck of the bottle can make it difficult to screw the collar ring onto the bottle without spilling, but you’ll want to make sure it’s secured on tight and that the nipple is sitting flush inside the plastic ring, or the bottle might leak. There is a notch on the collar to help you screw it on.

• The wide nipple base causes some of the remaining milk to pool inside the nipple unless you’re feeding at the right angle.

• As for the cap, it has no grip and can be hard to pop off, so may need both hands.

• The volume markings are just an indentation on the silicone and can be difficult to read, especially in bad lighting.

PLEASE NOTE: Although the above list of negatives about the Comotomo silicone baby bottles might seem longer compared with the brands listed thus far, a lot of these red flags simply have to do with learning how to use the bottles properly so that you don’t encounter these issues.

Tommee Tippee Closer to Nature Silicone Baby Bottle

Buy: Amazon
Cost: $13 per bottle on average
Key features: Created for breastfed babies, easy to travel with

Tommee Tippee silicone bottles are designed to mimic the shape and feeling of a breast.

The bottles are available in 5 oz and 9 oz in the original neutral design and newly in additional colors. Both sizes come with a slow flow silicone nipple – 6 flow rates are available for purchase. Please note that only the “Closer to Nature” Tommee Tippee nipples will fit these bottles.

Pros:

• Tommee Tippee silicone bottles have a wide neck and only 4 parts (including the cap), so they are easy to assemble and clean by hand (in addition to being dishwasher-safe). There is an additional piece included that’s optional to use – a travel seal. This is a flat disk that fits between the bottle and the collar that prevents leaks and spills when you’re traveling with a full bottle.

• The bottle is tapered towards the bottom and is easy and comfortable to hold, and the base of the bottle has a decent width to provide stability.

• A sturdy neck makes it easy to screw the collar ring on or put the cap in place without accidentally squeezing the soft body of the bottle and spilling milk.

• An anti-colic valve built into the nipple helps minimize swallowed air, preventing the symptoms of colic.

• Tommee Tippee uses silicone (food grade) with an anti-static coating which is advertised to help keep the bottles clean by repelling dust, dirt, pet hair, and other undesirable elements.

Cons:

• While Tommee Tippee is a silicone bottle and thus safer for baby than plastic, there is a plastic component at the neck of the bottle where the collar ring screws onto. Keep an eye out for cracks and signs of mold where the two materials meet.

• The measurements are etched into the silicone and can be hard to read.

• The slow flow nipple that comes with both bottle sizes can be too fast for the youngest babies. If your baby is a newborn to a 3-month-old, consider buying extra slow flow nipples for these bottles.

How to care for silicone baby bottles

Can silicone baby bottles be sterilized?

Silicone is stable at high temperatures and can be safely boiled to sterilize. Submerge the bottles in boiling water for 5 minutes, carefully remove and let air dry.

How often should you replace silicone bottles?

Silicone bottles may need replacing every 4-6 months, or sooner if the integrity of the bottle is in any way compromised. Check frequently for signs of mold – if you find black spots on the surface, discard the bottle.

How to get smells and stains out of silicone feeding bottles?

If you find that your silicone bottles have absorbed the smell of formula milk or detergent, try some of the common recommendations for removing odors from silicone:

1. Sterilize the bottle in boiling water.
2. Let the bottle soak in a 50-50 mixture of white vinegar and very hot water for 30 minutes. Scrub with a gentle sponge, rinse well.
3. Soak the bottles in boiling water. Then, apply a generous amount of baking soda all over the surface and rub it in to form a paste. Allow to sit until the paste dries out, and rinse thoroughly.

Follow the manufacturer’s instructions for any special care.

If you’re using or planning to use a breast pump or a specific bottle warmer, check the neck size of the bottle and bottle design before purchasing to ensure compatibility.
