The Comotomo Natural Feel bottle is the only mainstream baby bottle whose body is made entirely from medical-grade silicone — the same material as the nipple. This is meaningful because breastfed babies who reject other bottles are typically rejecting the hard plastic body, not just the nipple. When a baby grips a Comotomo, they feel the same soft, skin-like material they associate with nursing. BabyGearLab tested nipple acceptance rates across bottles and ranked Comotomo highest by a significant margin.
The ultra-wide neck is the second differentiator. It is physically large enough to insert an adult hand for thorough cleaning — something no narrow-neck bottle allows. This eliminates the residue buildup in bottle base corners that bottle brushes fail to reach in repeated washing. Both Mommyhood101 and BabyGearLab cited this cleaning feature as a genuine daily-use advantage.
The dual anti-colic vents handle most gas cases adequately. For the majority of parents — those without a baby with diagnosed severe colic — the Comotomo provides enough anti-colic performance alongside superior nipple acceptance and cleaning ease to earn the overall win. Mommyhood101 noted that it has 'slowly climbed into the top spot' over three years of testing as their top recommendation across multiple baby age groups.
What It Won't Do
The Comotomo has one functional weakness: it is harder to assemble a leak-free seal than narrow-neck bottles. The wide silicone gasket requires correct seating to prevent drips, which is a small learning curve that catches some parents off guard — particularly at 3 am. BabyGearLab flagged this as the bottle's main technical complaint. The translucent silicone also makes volume markings difficult to read. For parents under feeding plans from a pediatrician who require precise intake measurements, this is a genuine limitation. The soft body also warms more slowly in a bottle warmer due to the insulating properties of silicone versus plastic.
Dr. Brown's Natural Flow Options+ is the most clinically validated bottle in this review. Its patented two-piece internal vent system — consisting of a reservoir tube and vent insert — creates positive-pressure flow that eliminates the vacuum (negative pressure) that normally forms during feeding. Without that vacuum, babies don't need to suck harder to maintain flow, which means they ingest far less air. Pediatricians and lactation consultants specifically recommend Dr. Brown's for diagnosed colic and reflux.
The Options+ design adds meaningful flexibility: the vent system can be removed once a baby outgrows colic around 3-4 months, converting the bottle to a simpler design for daily use. Glass versions are available for parents who prefer no plastic in the milk path. At $5 per bottle in the 4-pack format, it's the best price-per-bottle among the reviewed picks.
For parents whose primary concern is gas and colic — not nipple transition or nipple confusion — Dr. Brown's anti-colic performance is unmatched.
What It Won't Do
The five-piece disassembly (bottle body, collar, reservoir, vent insert, nipple) is the Options+'s most-cited complaint. Reviewed.com and Mommyhood101 both flagged the extra parts as a significant daily-use burden when washing 8+ bottles per day in the newborn stage. The narrower nipple shape is the second real limitation. Breastfed babies who need to switch between breast and bottle regularly reject the Dr. Brown's nipple at higher rates than Comotomo or Tommee Tippee. For mixed-feeding families, the narrow nipple is a genuine incompatibility with the wide latch babies learn at the breast.
