4 oz/120ml Narrow Glass

Good glass quality and price

Good design

Excellent

Using them for 2 months now. No issue of colic as such. But, glass bottles need extra care. And it has too many parts, so need to be careful while washing.

Ordered from Australia knowing it's from USA. Delivery was quick and easy. As described can't wait to use for my twins, great quality and made of glass. Great bottles for newborns.

We tried several bottles before discovering Dr. Brown's Natural Flow Anti-Colic Options+, and it has truly been a lifesaver for us! Our 19-month-old son took to this bottle with ease, making feeding time much smoother and less stressful. Out of the three different bottles we tried, this one stood out as the best by far. The design of the Dr. Brown's bottle is thoughtfully crafted to reduce colic and gas, which has made a noticeable difference in our son's comfort. He seems to drink more comfortably and with less fuss, which has been a huge relief for us as parents. The anti-colic vent system is incredibly effective, minimizing air intake and reducing the likelihood of uncomfortable gas and bloating. Another standout feature is the ease of cleaning. The bottle is straightforward to disassemble, and the parts are durable and dishwasher-safe. This has made the whole feeding process a lot more manageable, especially during those late-night feedings. Overall, I can't recommend the Dr. Brown's Natural Flow Anti-Colic Options+ enough. It’s been a fantastic addition to our feeding routine, and I’m thrilled with how well it has worked for us. I’m giving it a solid five out of five stars for its effectiveness, ease of use, and the positive impact it has had on our son's feeding experience. If you’re looking for a reliable bottle that helps with colic and gas, this one is definitely worth a try!

We've had a great experience with the Dr. Brown's Natural Flow Anti-Colic Options bottles. our baby took to them easily. The vent system seems to make a noticeable difference, and the bottles are easy to clean and assemble. A great choice for parents looking for a reliable anti-colic bottle. Love that they are glass, I've dropped them numerous times and did not smash

After struggling with a colicky baby for weeks, these Dr. Brown’s bottles have been a lifesaver. The internal vent system really does make a difference - we’ve seen a dramatic reduction in gas, spit-up, and fussiness during and after feeding. The “natural flow” nipples work well for both breastfed and bottle-fed babies. The pacing feels more natural compared to standard bottles, and there’s less gulping and air intake. Our baby seems much more comfortable during feeds and settles easier afterward. The quality is solid - bottles feel durable and the nipples have held up well through multiple sterilizations. The measurement markings are clear and accurate, which is helpful for tracking intake. Fair warning: these bottles have more parts to clean than standard bottles. The vent system means extra pieces to wash and sterilize, which can be tedious with multiple daily feedings. You’ll also want to buy extra vent inserts since they’re small and easy to lose. The price point is higher than basic bottles, but when you’re dealing with a colicky baby, the relief is worth every penny. We tried several other “anti-colic” bottles first, but these were the only ones that actually delivered results. Highly recommend for parents dealing with feeding issues - just be prepared for the extra cleaning time.​​​​​​​​​​​​​​​​
