Glass bottles are hands down better than plastic bottles. I have been using these for the last 1 year approximately . Here are some of the pros: 1. Superior heat conductivity: when you are warming up a bottle at night the glass bottles is faster in getting the heat transferred to the liquid compared to your plastic. 2. Easier to clean: glass bottles are easier to clean as food residue are less likely to adhere to the walls of the bottle. 3. Longevity: plastic bottles deteriorates over time and the scratches from washing makes the bottle milky. The glass bottles are still shiny and there are no visible scratches on the bottle. 4. Healthier: no risk of shedding microplastics when heated. 5. Microwaveable: can easily heat up a bottle in the microwave. Some Cons: 1. Can break easily: I have noticed the necks of the bottle can crack even from small knocks against other bottles. Will break if falls from 4/5 feet height. 2. Heavier: traveling with multiple bottles in the baby bag can add to the weight. 3. Doesn’t come in smaller size: it only comes in the 8oz size. Edit, Jan 24: another thing I forgot to mention was, the vent, that helps to reduce burping; It is a royal pain in the bottom when it comes to washing, it is the bane of my existence. But it is what it is, unless a design innovation happens parents will have to bear this pain. Tip: The bottle will heat up 8 oz of refrigerated whole milk, in 40-50 seconds. It can also heat up 8 oz of refrigerated formula in 40-50 secs. Net: You may want to buy these if you don’t like plastic. Very solid product. This review is based on my personal experience and use. I have not been paid for this review.

🌟🌟🌟🌟🌟 The Dr. Brown's Natural Flow Anti-Colic Options+ Narrow Glass Baby Bottle is fantastic! These bottles are well-designed and made from high-quality glass, which makes them durable and easy to clean. The anti-colic system works wonders, helping to reduce gas and fussiness during feeding. I appreciate the Level 1 Slow Flow nipples, which are perfect for newborns and help prevent overfeeding. The 8 oz size is just right for growing babies, and the two-pack is super convenient. Overall, a top-notch product that I highly recommend for parents looking for a reliable, safe, and effective feeding solution!

I wish I had known about these from the start! I’m so happy to have glass bottles. I have been using doctor browns bottles (plastic) since my son was born. Over the last few months, reading more and more about the harm micro plastics are doing to our bodies, I decided to switch all of our plastic food items over. This bottles are great. Leak proof, just like the plastic. And so far they have passed the “drop test” from my baby. I wouldn’t say throw in onto the hard cement but definitely durable for high chair/crib drop.

The glass 4oz Dr Browns bottles are the perfect combo of safe easy feeding for my baby. They are light weight, and do not break when dropped. I haven’t experienced any leaking or cracks either. They are easy to clean and store. And they come with the same filter inserts as the plastic bottles so if you enjoy the benefits of those, they work best for my kid, then you will like this glass version. Also, glass gets colder than plastic so these keep my breastmilk soooo cold in the fridge. I guess the drawback is that it takes longer to warm up a glass bottle. But all in all these are the only bottles we feed our son with and have not had any issues or concerns. We feel great about cutting down his exposure to harmful microplastics and chemicals found in them.

the glass is worth it. i’ve never had leaking issues when i use my glass bottles. they are sturdy and a good weight.

Let me introduce you to Dr. Brown’s Natural Flow Anti-Colic Options+ Narrow Glass Baby Bottle—aka my secret weapon against my baby’s colic struggles. This bottle is an absolute game-changer, and I truly believe it’s helped make feedings a much smoother, happier experience for both me and my little one. First, let’s talk about the anti-colic design. If you’ve ever experienced the agony of your baby crying and fussing during and after feeds, you know how frustrating it can be. This bottle has a vent system that helps reduce air intake, which in turn helps prevent colic, gas, and spit-up. The result? My baby is now much less gassy and much more content after feedings. Honestly, I can’t put a price on that kind of relief. The narrow glass design is a nice touch, too. Glass bottles are durable, easy to clean, and don’t hold onto any funky odors (like plastic sometimes does). It’s also eco-friendly, and I just feel better knowing I’m using a natural, safe option for my baby. Plus, the 4 oz/120 mL size is perfect for those early feedings—just the right amount without feeling like there’s too much wasted milk. The Level 1 Slow Flow nipple is fantastic for newborns, allowing for a gentle and controlled flow, which is perfect for preventing overfeeding or choking. I love how natural the flow feels for my baby—just the right amount of milk, without rushing through the bottle too fast. Lastly, the bottle is easy to clean (a big plus when you’re dealing with multiple feedings a day) and it’s compatible with other Dr. Brown’s products, so if you’re already using their pacifiers or other bottles, everything works together seamlessly. Bottom line: The Dr. Brown’s Natural Flow Anti-Colic Options+ Bottle is a must-have for any parent struggling with colic or gas issues. It’s well-made, easy to clean, and it really works to reduce discomfort for your baby. If you want a peaceful feeding experience, this bottle is your new best friend. 10/10, highly recommend for every parent looking to soothe their baby and make feeding time easier!

A little hard to wash, but really sturdy and durable alternative to glass bottles that stain and smell over time.

Great bottles. Love that they are glass. Easy to wash with the little bristle brush provided

nos encantan, mi bebé los agarro luego luego, tengo 4 de vidrio de 4 oz y 4 de vidrio de 8 onzas, desde que los usamos mi bebé ya no saca tantito pedito, ni tiene malestar como solía con otros biberones, aparte de que están bonitos y resistentes, le funcionaron a la perfección para sus cólicos, los amamos.

Es buen producto pero la verdad nunca lo usé por la lactancia

As a doting grandmother I wanted the best glass bottle for hygiene and no plastics worry. Dishwashes every day and comes up sparkling

This the only one my baby accept to get.
