Our Top Picks
Philips Avent Natural Baby Bottles, Medium Flow, 4-Pack
Philips Avent
- ✓Available in newborn and first-flow nipple options
- ✓Wide, breast-shaped nipple for latch-matching
- ✓AirFree anti-colic valve
- ✓3 parts per bottle for easy washing
- ✓Polypropylene, BPA-free
Pros
- Newborn-specific flow nipples slow things down enough for early sucking and swallowing coordination
- Wide nipple shape eases the transition for babies who will also be breastfed
- Fewest parts of any bottle here, a real time saver during frequent newborn feeds and washes
Cons
- AirFree valve only vents fully when held mostly vertical
- 9oz size is more bottle than a newborn needs, size down if buying newborn-specific bottles
- Nipple collapse reported occasionally once babies move to faster flows
Best overall for newborns. Widely available newborn-flow nipples and the easiest daily cleanup routine of any bottle here.
Dr. Brown's Options+ Narrow Glass Baby Bottles, 4oz/8oz 4-Pack
Dr. Brown's
- ✓4oz size included in this 4-pack, right-sized for early feeds
- ✓Internal vent system that routes air away from milk
- ✓Level 1 slow-flow nipple included
- ✓Borosilicate glass, BPA-free
- ✓Dishwasher-safe, top rack
Pros
- 4oz bottles in this pack match a newborn's actual intake far better than a 9oz bottle
- Vent system has the deepest anti-colic research history in this category, useful for gassier newborns
- Level 1 nipple is genuinely slow, appropriate for the first weeks
Cons
- Most parts per bottle of any major brand, a real burden during round-the-clock newborn feeds
- Vent system needs correct threading or it leaks at the collar
- Glass bottles are heavier to hold one-handed during long newborn feeding sessions
Best for newborns with noticeable gas or fussiness. The vent system's track record makes it worth the extra parts.
Comotomo Baby Bottle, Double Pack, 5oz
Comotomo
- ✓5oz size, right-sized for newborn feeds
- ✓100% medical-grade silicone body
- ✓Ships with a slow-flow nipple for 0 to 3 months
- ✓Dual anti-colic vents
- ✓Skin-like soft texture
Pros
- 5oz size and slow-flow nipple are appropriately scaled for a newborn's actual intake
- Silicone body's soft texture is the closest tactile match to skin, useful for babies also breastfeeding
- Wide opening lets tired parents wipe most of the bottle clean without a brush at 3am
Cons
- Among the pricier options per bottle, a real cost when buying enough for round-the-clock newborn feeds
- Wide barrel does not fit every bottle warmer
- Silicone shows fingerprints and grip marks faster than hard plastic
Best for newborns who will also breastfeed. The soft, breast-like nipple eases combo feeding in the early weeks.
Nanobebe Breastmilk and Silicone Baby Bottle Complete Set
Nanobebe
- ✓5oz size included, appropriate for newborn intake
- ✓Breast-shaped bowl design for fast, even warming
- ✓Slow-flow anti-colic vented nipple
- ✓Bundled with a pump adapter and pacifiers
- ✓BPA, PVC, lead, and phthalate-free
Pros
- 5oz size matches a newborn's early intake without needing to portion down from a larger bottle
- Fast, even warming helps during frequent newborn feeds when every minute of a fussy wait matters
- Complete set's pump adapter simplifies a newborn pumping and bottle-feeding routine from day one
Cons
- Smallest ratings volume of the brands compared here
- Priced as a full set rather than a simple starter bottle pack
- Wide bowl shape needs a specific bottle warmer insert to heat evenly
Best for parents establishing a pumping routine from birth. The fast warming and included pump adapter cover both ends of that workflow.
The first bottle a newborn ever takes sets the tone for weeks of feedings to come. Size and flow rate matter more here than almost any other stage.
A newborn's stomach holds 1 to 3 ounces in the first couple weeks, which makes a 4oz or 5oz bottle the right starting size, not the 9oz bottles marketed for older infants.
Philips Avent's newborn and first-flow nipples, paired with a simple 3-part bottle, make for the easiest early routine, especially for parents managing feeds at 3am with limited patience for reassembly.
Dr. Brown's Options+ 4oz bottles bring the category's most established anti-colic vent system for newborns showing real gas or fussiness, while Comotomo and Nanobebe cover soft-nipple and pumping-focused needs respectively.
The Best Newborn Bottles at a Glance

Best for combo feeding: Comotomo Double Pack. A soft, breast-like nipple that eases the switch between breast and bottle.
Best for a pumping routine: Nanobebe Complete Set. Fast, even warming plus a pump adapter, built for newborn pumping schedules.
What Actually Matters at This Stage
Size down, not up. A 4oz or 5oz bottle is genuinely the right size for a newborn. A 9oz bottle isn't dangerous, it's just harder to gauge intake against and adds unnecessary bulk for a tiny feed.
Start at the slowest flow, always. Every brand in this list offers a newborn or first-flow nipple. Skipping straight to a medium flow because it "seems faster" risks gulping, choking, and more swallowed air, not less.
Buy more bottles than you think you need. Newborn feeding happens 8 to 12 times a day. 6 to 8 bottles gives enough buffer between wash cycles without running out mid-day.
