Dr. Brown's Anti-Colic Options+ Narrow Glass Baby Bottle with Level 1 Slow Flow Nipple, BPA-Free, 4 oz/120mL, 4-Pack

"4.0 out of 5 stars" - What I liked:The anti‑colic internal vent system is a big plus. According to the manufacturer, it’s “clinically proven to reduce colic… decreases spit‑up, burping and gas.”Dr. Brown's+2Amazon+2In practice, our baby seemed calmer during feedings and had fewer burps and gas episodes right after switching to this bottle.The glass bottle is high quality: borosilicate glass, heat and thermal shock‑resistant (so you can handle warm/hot to cool transitions) according to specs.AmazonI like that glass instead of plastic, for durability, feel, and avoiding plastic concerns.The nipple shape is thoughtful: described as “breast‑like nipple shape” to encourage proper latch and smoother transition between breast and bottle.Dr. Brown's+1Our baby took to it quite readily.Flexibility/growth consideration: The internal vent system can be removed as baby grows and their feeding needs change — so you don’t necessarily need to switch to a totally different bottle brand later.Amazon+1Care/cleaning is fairly straightforward: It is dishwasher safe (top rack), safe to use in electric/microwave sterilizers or boiling water (as per manufacturer).Amazon+1What to consider / minor drawbacks:With all the parts (vent system + narrow glass bottle + screw top + nipple), there is a bit more assembly / cleaning than the simplest bottle on the market. If you prefer ultra‑minimal, this might be a bit more work.Glass, while great, is heavier than plastic — so during late‑night feedings or travel it’s something to keep in mind (less drop‑resistant as well, though the borosilicate helps).The “narrow” neck version is good for compatibility/flow, but some users may prefer the wide‑neck version for easier pouring, cleaning, or when using bottle brushes.The “slow flow” nipple (Level 1) is perfect for newborns, but if baby feeds faster / gets older you’ll need to upgrade to the next flow level; worth planning ahead.Price is a bit higher than basic bottles, especially for glass + anti‑colic system combined — but given the features, I think the premium is justifiable if you need the anti‑colic support.My verdict:If you’re looking for a bottle that goes beyond “just a bottle” and offers real anti‑colic technology + good materials + thoughtful design, this Dr. Brown’s Options+ Narrow Glass Bottle is a strong choice. For us it delivered what it promised: fewer feeding struggles, calmer baby, and a product that feels premium. I’d give it 4.5 out of 5 stars.
