How To Choose The Right Feeding Bottle For Your Newborn

Choosing the right feeding bottle for your newborn comes down to three things: a small capacity matched to a newborn’s tiny stomach, a slow-flow teat, and a body-safe material such as PPSU, polypropylene (PP), or glass. Most parents start with a 120 to 180 ml wide-neck bottle and a slow-flow teat, then size up as their baby grows.

Quick Answer

For the first weeks, pick a 120 to 180 ml (4 to 6 oz) bottle with a wide-neck opening, a slow-flow or newborn-stage teat, and a BPA-free material. Wide-neck bottles are easier to fill and clean, and a slow flow keeps feeding paced and comfortable. As your baby grows, the size, flow, and even the material you choose will need to change with them.

How Much Milk Does A Newborn Need?

In the first few days of life, most babies take in only 1.5 to 3 ounces, or 45 to 90 millilitres, every 2 to 3 hours, a smaller amount than many first-time parents expect. That volume rises gradually to about 120 to 150 ml (4 to 5 oz) by around two months. Because most newborns feed 8 to 12 times in a 24-hour period, a 120 to 180 ml bottle is usually the right starting size.

A wide neck opening also makes scooping formula and cleaning the bottle easier, which is why it is standard on most nursing bottle ranges for newborns.

What Teat Flow Rate Does A Newborn Need?

The teat decides how quickly milk reaches your baby. Too fast causes gulping and coughing; too slow leaves a hungry baby frustrated. As a general rule, babies fed by both breast and bottle may benefit from a slower-flowing teat that better matches the flow rate of human milk, which helps avoid a strong bottle preference over the breast. 

This matters more than most parents realise, since flow is one of the few feeding variables you can actually control.

Flow labels are also not standardised across brands. Controlled testing of bottle nipples found flow rates ranging from 2 ml to 85 ml per minute across different stages, with marked variations even among nipples marketed under the same ‘slow’ category from different manufacturers. As a result, a slow-flow nipple from one brand may flow noticeably faster than one from another.

See our guide on choosing the right bottle teat for how shapes and stages differ.

What Is An Anti-Colic Bottle?

An anti-colic bottle is a bottle with a built-in venting system that vents air out of the bottle instead of letting your baby swallow it, which reduces gas, fussiness, and spit-up after a feed. If your baby seems uncomfortable after bottle feeds, this feature is worth prioritising. We cover this in more depth in What Is an Anti-Colic Bottle.

Bottle Material: PPSU, PP, Or Glass?

PPSU is lightweight and shatter-resistant with strong heat tolerance for sterilising; PP is similarly light and budget-friendly; glass is heavier but never scratches or clouds. 

All three sold today are BPA-free and comply with global standards, including the US FDA 2012 ban and Malaysia’s Ministry of Health prohibition on BPA in infant feeding bottles under the Food Regulations 1985. The right choice ultimately comes down to how you sterilise day-to-day rather than any one material being objectively superior.

For help matching material to your sterilising method, see our FAQ on choosing a bottle material.

How Do You Bottle Feed A Newborn Safely?

Hold your baby close and avoid propping or leaving the bottle in their mouth unattended, as this increases the risk of choking and ear infections. Do not pressure a baby to finish a bottle once they show signs of fullness. Malaysia’s own Ministry of Health nutrition guidance advises against feeding a baby lying flat on their back, since this raises choking risk, and recommends always burping a baby after a feed, alongside avoiding BPA exposure in milk bottles altogether.

Frequently Asked Questions

What size bottle is best for a newborn?

A 120 to 180 ml (4 to 6 oz) bottle suits most newborns, who typically drink only 45 to 90 ml (1.5 to 3 oz) per feed in the first weeks.

Do newborns need a slow-flow teat?

Yes. A slow or newborn-stage flow matches how gently a newborn feeds and helps babies who are combination-fed maintain a preference for breastfeeding.

Is PPSU or glass better for a newborn bottle?

Neither is objectively better, since both are BPA-free. PPSU is lighter and travel-friendly; glass is heavier but resists scratching and odour over time.

How do I know if my baby needs an anti-colic bottle?

If your baby is fussy after feeds, spits up often, or seems gassy, an anti-colic bottle with a venting system is worth trying.

How many bottles do I need for a newborn?

Six to eight bottles is practical for a fully bottle-fed newborn feeding every 2 to 3 hours, allowing time for washing and sterilising between uses.

Six Decades Of Feeding Research Behind Every Pigeon Bottle

Pigeon was founded in Japan in 1957 on direct research into infant sucking behaviour, and went on to introduce Japan’s first wide neck nursing bottle design, a hygiene improvement still standard today. That research foundation is why Pigeon is recognised as a market leader in mother-and-baby care products across the region. It shapes the SofTouch™ wide neck bottle range now, offered in PPSU, PP, and glass, with a built-in anti-colic system, a clinically tested Latch-On Line, and BPA- and BPS-free construction in 160 ml and 240 ml sizes matched to compatible teat stages, so the bottle you start with can grow with your baby.
