9 Best Baby Bottles, Tested by Experts and Parents

✔️ BEST FEATURE: Dr. Brown's bottles have a distinctive anti-colic vent down the middle, which you can leave in or take out (hence the name "Options"). The brand claims their internal vent helps reduce spit-up, burping, and gas.

✔️ TESTING NOTES: Dr. Brown's bottles won a previous Good Housekeeping Parenting Award. Testers said they felt the bottles reduced their babies’ fussiness after feedings, and testers who were also breastfeeding said their babies willingly took the Dr. Brown's nipple.

The bottles have earned tens of thousands of five-star reviews online, and are also a favorite of many of our staff parents. "Dr. Brown's was the one I used most," said former Chief Technologist & Executive Technical Director Rachel Rothman. "I had three kids with reflux and found the anti-colic feature helped with that."

"What I especially like about these bottles is that they grew with both my babies," says Nutrition Lab Director Stefani Sassos, a registered dietitian whose daughter is now 4 and son is now 17 months. "You can upgrade to a sippy spout, which helped us transition and saved me from having to spend money on new cups and bottles each time."

Sassos also said, "I breastfed both and they had no issues with using these."

✔️ MORE INFO: Dr. Brown's bottles come in the classic long, narrow shape, shown, and also in a 5-ounce, wide-neck version, with many more variations as well. There are even Dr. Brown's Options+ glass bottles.

The vent is an extra part to clean. The set comes with a tiny bristle brush to help. The Dr. Brown's Bottle Cleaning Brush with a sponge top is a popular tool for cleaning the bottles themselves.

✔️ BEST FEATURE: This pack of a dozen bottles gets your cost-per-bottle down to under $2.

✔️ TESTING NOTES: While manufacturers work to innovate the baby-bottle market, these traditional, affordable bottles continue to be a favorite of both babies and parents. In this century, they've been given a "twist" design that makes them easier to grip.

"I picked these up from the supermarket in a pinch and my son really liked them. They actually became his preferred bottle," one mom told us. The price of the plastic version is hard to beat, and even the glass version is less than $3 dollars a bottle.

✔️ MORE INFO: It's a little tough to see the ounce marks on the side, since they are clear like the bottle. But with some practice and time, it seems most parents get used to expertly filling even half or three-quarters of any bottle in the dark with their eyes closed.

✔️ BEST FEATURE: Nearly every bottle on the market will say it's the closest thing to breastfeeding. We give props though to this bottle, though, for the controlled-pace nipple that doesn't overwhelm a nursing infant with milk but responds well to their stop-and-start sucking.

✔️ TESTING NOTES: This brand's big innovation about 40 years ago was introducing the fat, wide shape of both the bottle and the nipple. The roundness of the nipple might feel more like a breast to babies (hard to say, since they can't tell us!) and as parents, we can vouch that wide bottles can be easier to clean. Now many other companies have taken note and also sell wide-neck versions of their bottles.

The Natural bottle comes in colors, too, such as pink and green.

We also recently tested the Natural in the glass version with consumer testers. Though several noted that they're heavy, those concerned about plastic liked the glass option. "I previously used the plastic Philips Avent bottles with my now-2-year-old. After doing more research on microplastics when I was pregnant with my second, I knew I wanted to switch to the glass," one parent said.

✔️ MORE INFO: Phillips Avent sells nipples in five different flow rates so you can adjust for a faster flow as your baby grows and takes in more milk, more quickly.

✔️ BEST FEATURE: MAM bottles unscrew at the bottom and the top, which allows you to clean them thoroughly.

They also have a unique "self-sterilization" feature wherein you unscrew the bottle parts, add an ounce of water to the bottom piece, load in the nipple top and then the main sleeve and finally put the cap on top, and microwave it all for three minutes.

"I’ve never seen anything like that with any other bottle," one tester noted. "It would be a great bottle for traveling when you don’t have access to your sterilizer or to boiling water."

✔️ TESTING NOTES: These were a winner in our most recent Good Housekeeping Parenting Awards. A parent tester said, “We’ve had a difficult time convincing our baby to take a bottle, but he took to this bottle on the first try!” Another said, “My baby, who is mostly breastfed, was able to latch easily.”

✔️ MORE INFO: This is the small size and extra slow flow nipple for newborns. They come in other colors including blue and lavender. After a couple of months your baby might graduate to the 9-ounce size with a nipple that has a faster flow. MAM also makes a 6-ounce glass bottle.

Our Kitchen Appliances & Innovation Lab pros don’t suggest microwaving a MAM bottle after each use, only occasionally, and note that this is a helpful option when traveling, when you're away from your dishwasher. Because it comes apart to self-sterilize, the MAM bottle has more parts than other bottles on our list.

✔️ BEST FEATURE: When we gave the Chicco Duo Hybrid its most recent Parenting Award, we noted that parents who prefer using glass to feed their babies but are nervous about potential breakage should check out this invention. The inside (where milk touches) is glass, bonded to a plastic outside for durability.

✔️ TESTING NOTES: Chicco developed the glass/plastic hybrid using pharmaceutical technology, creating a permanent bond between the glass inner layer and a plastic outer layer. The invention is called "Invinci-Glass."

A recent tester said, “This bottle solves the issue of not wanting to expose your baby to extra plastic bottles but not having to deal with heavy, breakable glass bottles.” If your child's daycare won't accept glass bottles, but you're trying to avoid traditional plastics, this is a great solution. "I love everything about this bottle," another tester said.

✔️ MORE INFO: You can also get Duo bottles in pink trim and the bottle also comes in a larger 9-ounce size.

These can be cleaned in the dishwasher top rack and can be sterilized in an electric sterilizer or by boiling them for a few minutes, but you shouldn't use a microwave sterilizer with the Duo.

✔️ BEST FEATURE: Amid the plastic-vs.-glass debate, Comotomo introduced an alternative material for baby bottles: soft, squishy silicone. Silicone is lightweight, durable, and easy to clean. It also doesn't get stained with milk residue like some plastic bottles.

✔️ TESTING NOTES: "When my daughter was in one of her bottle-rebellion phases, she did still accept the Comotomo," Rothman says. That was echoed by a tester who told us, "When my daughter was refusing to suck on a bottle, I liked that I could squeeze some milk out of these right into her mouth."

✔️ MORE INFO: Silicone can be easier for independent-minded older babies to hold by themselves. However, it's sometimes a little unsteady when placed down on a surface. Plus, it's tough to get a name sticker, like you might use for daycare, to adhere on a silicone bottle (we recommend placing one on the colored rim).

These silicone baby bottles can be hand-washed, run through the dishwasher, boiled for five minutes to sterilize, or sterilized in a steam sterilizer. However, don't put silicone in a UV sterilizer, which speeds the material's degradation.

✔️ BEST FEATURE: NUK's bottle has a vented nipple to cut down on gas and colicky behavior. The nipple's soft texture and ergonomic design is made to accommodate the way a baby naturally holds their tongue while nursing, to reduce nipple confusion.

✔️ TESTING NOTES: Testers and a staff parent told us their baby took a liking to NUK. Said one, "My son is exclusively drinking breastmilk and mostly directly from me, so I was pleasantly surprised to find he liked drinking expressed milk out of this bottle too."

A blue temperature indicator on the side disappears when the milk is too hot for a baby to drink, then reappears as the milk cools down and is safe and ready for feeding. It's one of the only bottles we know of with that feature.

Senior Reviews Writer & Analyst Olivia Lipski says her husband prefers using this bottle with their baby because it doesn't leak, though online reviews are more mixed regarding the bottle being leakproof and durable."It doesn't leak at all when she's eating from it. The others have small drops that escape and get on her clothes," Lipski says.

✔️ MORE INFO: There's now a glass version of the Simply Natural bottle. And NUK makes a newer bottle that is designed for newborns and infants, called NUK Perfect Match, in a 5-ounce size. It's also vented, and includes a temperature indictor.

✔️ BEST FEATURE: Because they're silicone with a protective plastic shell, these bottles are super durable. The silicone inner pouch collapses as your baby sucks, forcing out all the milk without letting them take in too much air. This collapsible design helps cut down on gas and reflux without any special vents.

✔️ TESTING NOTES: Aesthetically, we appreciate the cute mushroom shape and note that they are easy for older babies to hold by themselves. "I really liked how these worked down the line with their sippy-cup lids," says Rothman.

To assemble these properly so they don't leak, you do need to take the time to line up the silicone inner pouch with the exterior plastic shell and be sure they're sealed tightly together. Then you add the nipple. If you're in a rush, it can feel like one extra step compared to a traditional bottle.

✔️ MORE INFO: Boon's bottles come in seven sophisticated color sets including a colorblock version and, at the other extreme, a set with a white, gray, and black bottle.

To clean them, you can flip the silicone part inside-out.

✔️ BEST FEATURE: Lansinoh is a nursing-first company; it tracks that their bottle nipple is designed to compliment breastfeeding and that their bottle was easily accepted by some of our testers with newborns.

✔️ TESTING NOTES: "My first child wasn't picky at all," one tester said. "But my second was super picky and we finally got her to take the Lansinoh bottles. They seem most comfortable and similar to breastfeeding for her. My only complaint is that they only make glass bottles in the 8-ounce size so we have to wait until she's older to use glass, which we prefer."

Similar to other bottles on this list, Lansinoh bottles use a vented nipple to cut down on gas and reflux; it's also a controlled-flow nipple so that your baby can use roughly the same actions to drink from these as they use while nursing.

✔️ MORE INFO: If you're a combo mom, doing some mix of breastfeeding and bottlefeeding, Lansinoh has a lot of products to support that journey, from breast pumps to nursing pads.
