Best Baby Formula for Newborns: A Buyer's Guide

The best baby formula for newborns here is Similac 360 Total Care Ready-to-Feed, sold as a pack of 12 pre-mixed 2 fl oz bottles that skip every measuring step during a 3am feed. If you have moved past those first blurry weeks and want a container that lasts, the 20.6 oz Similac 360 Total Care powder is the better buy.

The 30-second shortlist for the best baby formula for newborns runs like this: the ready-to-feed Similac wins the first month, the 20.6 oz powder version wins from month two onward, and if a cow-milk protein does not settle well, Kabrita's 28 oz goat-milk tin is the alternate. The rest of this guide explains why the protein source matters more than the marketing.

Best baby formula for newborns at a glance

How I narrowed the field to five

Three cuts got the field to five. First, anything outside the 0-12 month indication was out, so toddler formulas and follow-on stages did not make the list even where the brands overlap. Second, anything without a clearly labelled protein source (cow milk, goat milk, organic cow milk) was out, because the protein is the single most useful thing a parent can compare across tins. Third, anything with fewer than two active sellers on the listing was dropped so you are not stuck if one seller runs dry.

What survived is a small, tight set: two cow-milk options from Similac (one liquid, one powder), one organic cow-milk powder from Earth's Best, and two goat-milk powders from Bubs and Kabrita. That covers the four routes a newborn parent actually chooses between: pre-mixed convenience, standard powder, organic, or a gentler protein.

• Cow-milk powder, entry: Bubs is a goat option in the entry position, no cow-milk entry powder survived
• Cow-milk powder, premium: Similac 360 Total Care
• Organic cow-milk powder: Earth's Best
• Goat-milk powder, entry: Bubs Whole Goat Milk
• Goat-milk powder, premium: Kabrita
• Ready-to-feed liquid: Similac 360 Total Care 2 fl oz bottles

Cow milk, goat milk or organic: what actually decides it?

Most newborn formula guides compare marketing claims. That is not what decides it. The protein source is.

Cow-milk formula is the default in the United States and what most pediatricians reach for first. Similac 360 Total Care and Earth's Best Organic both sit in that lane, one conventional and one certified organic. If your newborn tolerates cow-milk protein, either works and the choice comes down to whether organic sourcing matters to you.

Goat-milk formula is a different protein entirely. Kabrita's listing describes an A2 protein that "forms softer curds during digestion than cow milk proteins", and Bubs makes a similar claim on its tin. Those are the manufacturers' words, not a measured outcome, and neither replaces a pediatrician's advice on cow-milk protein allergy or sensitivity. But if a cow-milk formula has your baby spitting up or straining, the goat-milk route is the alternate the market has settled on.

Organic sits inside the cow-milk category. Earth's Best is the only certified organic pick in this set, and the listing states it contains no added corn syrup. That is a real point of differentiation, since corn syrup solids show up as the carbohydrate source in many standard formulas.

The keyword modifier here, "for newborns", deserves a note. Every product in this guide is labelled 0-12 months by the manufacturer, but Amazon's search does not verify that. If you are shopping outside this list, read the age range on the tin before anything else. Two of the pediatric-grade indications a parent might expect (a specific "stage 1" callout, a hypoallergenic label) are not on any of these listings, so if your pediatrician has specified either, look further.

Ready-to-feed versus powder for a newborn

Ready-to-feed bottles win the first two weeks. Powder wins everything after that. The tradeoff is not subtle.

Similac's ready-to-feed pack gives you 12 sterile 2 fl oz bottles, each one already at the right dilution. You uncap it, screw on a nipple, feed. There is no measuring, no water source to worry about, no bottle to wash beyond the nipple. For a 2am feed with a partner who has not slept in three days, that matters.

The catch is volume. Twelve 2 fl oz bottles is 24 fl oz total, and a newborn's daily intake climbs quickly past that in the first month. A single pack will not last a full day of exclusive feeding by week three or four. That is why the ready-to-feed pack is a starter pick, not a long-term one, and why the powder version of the same formula is the sensible transition.

Powder tins scale. The Similac 360 Total Care powder is a 20.6 oz tin, Bubs is 20 oz, Earth's Best is 21 oz, and Kabrita is 28 oz. All four use the same basic method: level scoop per 2 fl oz of water, cap and shake. Kabrita's tin is the largest in the set at 28 oz and 1.76 lb, which is roughly a third more powder than Similac's 1.29 lb tin.

How long does one container last a newborn?

Volume matters because you will be reordering. A rough map of what each pick puts in front of you:

1. Similac Ready-to-Feed, 12 × 2 fl oz: 24 fl oz of prepared formula, or roughly one day for a newborn approaching a month old.
2. Bubs Goat Milk, 20 oz powder tin: a mid-size container that mixes into many more bottles than the ready-to-feed pack.
3. Similac 360 Total Care Powder, 20.6 oz tin: essentially the same yield as Bubs, in a 5 x 5.95 x 4.32 in canister.
4. Earth's Best Organic, 21 oz tin: marginally more powder than Similac's tin, in a similar 4.88 x 5.1 x 5.1 in canister.
5. Kabrita Goat Milk, 28 oz tin: the largest tin here at 1.76 lb, in a 6.25 x 5 x 5 in canister.

The listings do not publish a "bottles per tin" figure, and the exact yield depends on how many fluid ounces per feed your baby is taking. What the sizes do tell you is that Kabrita gives the most powder per tin, and that the ready-to-feed pack is a fundamentally different unit: pre-mixed liquid measured in fluid ounces, not powder measured by weight.

1. Similac 360 Total Care Ready-to-Feed Baby Formula — Best overall

The right pick for the first weeks home, when convenience beats every other consideration.

Best for: the first weeks home, night feeds, and travel Skip it if: you want a large container for daily bottle prep

This is the only ready-to-feed product in this set, and that alone earns it the top spot for newborns. The pack contains 12 individual 2 fl oz bottles, each weighing 2 oz, each pre-mixed and sterile. There is no water to measure, no scoop to level, no shaking. For a family in the first two weeks with a newborn, that is the single biggest time saver on the shelf.

The trade-off is exactly what you would expect. 24 fl oz total per pack does not sustain a baby who is climbing toward 24 to 32 fl oz per day, which is where a full-term newborn typically ends up by the end of the first month. You will burn through packs quickly. It is also the cheapest of the five picks in this set, which reflects the small format rather than the format being cheap to run day after day. That is why most families use it alongside a powder tin.

Pros:

• Pre-mixed, no water or scoop needed
• 12 sterile 2 fl oz bottles per pack
• Same Similac 360 Total Care formula as the powder version
• The cheapest pick here to try
• Only ready-to-feed option in this guide

Cons:

• 24 fl oz total does not last a full day of feeds in month one
• Smaller unit means more frequent reordering
• No listed dimensions on the pack for storage planning

2. Similac 360 Total Care Baby Formula Powder — Best for heavy use

The natural transition from the ready-to-feed pack once you settle into a routine.

Best for: families settling into a powder routine after the first weeks Skip it if: you need pre-mixed bottles ready in seconds

The 20.6 oz tin weighs 1.29 lb and measures 5 x 5.95 x 4.32 in, so it fits on a standard kitchen shelf next to a bottle warmer without eating into the space. It is the same 360 Total Care formulation as the ready-to-feed pack, which matters: if your newborn does well on the liquid, moving to the powder keeps the protein source and the additive profile consistent. Switching brands during the first weeks tends to unsettle a baby's digestion, and this is the cleanest way to avoid it.

The listing calls out an "exclusive 5 prebiotic blend" and states no rbGH or rbST, which are the manufacturer's claims about how the milk source is managed. What separates this pick from Bubs and Earth's Best in the set is not the tin size, which is roughly comparable, but the price position: this is the most expensive of the three mid-size tins, and you are paying for the Similac name and the shared formulation.

Pros:

• Same 360 Total Care formulation as the ready-to-feed pack
• 20.6 oz tin, 1.29 lb, easy to store
• Two active sellers on the listing
• Manufacturer states no rbGH or rbST
• Released 2023, current formulation

Cons:

• The most expensive of the three mid-size cow-milk tins here
• Requires water, sterile prep and mixing at every feed
• No published organic certification

3. Bubs Whole Goat Milk Infant Formula for 0-12 Months — Best for families

A goat-milk option that sits in the entry price band, not the premium one.

Best for: parents drawn to a goat-milk option without a premium price position Skip it if: your pediatrician has told you to stay on a standard cow-milk formula

Bubs is the second-cheapest pick here and the only entry-priced goat-milk option in the set. The 20 oz tin weighs 1.25 lb, which is the lightest powder tin in this guide by a small margin. The listing states the formula is made in Australia with whole goat milk, and lists DHA/ARA, omega-3 and omega-6 as included nutrients. Bubs says the product is non-GMO with no corn syrup, artificial colours, flavours or preservatives.

Preparation is the standard scoop-per-2-fl-oz method. Where Bubs earns its place in this set is the combination of the goat-milk protein source and the price position: Kabrita is the premium goat-milk option, so if you want to try goat without committing to the top of the range, Bubs is the alternate. It sells faster than Earth's Best and Kabrita in this set, which suggests families are finding it.

Pros:

• Whole goat-milk protein source
• Second-cheapest of the five picks
• 20 oz tin, 1.25 lb, lightest powder here
• Listing states no corn syrup or GMOs
• Manufacturer states DHA/ARA and omega-3/6 included

Cons:

• Fewer listed dimensions than Similac or Kabrita
• Not certified organic on the listing
• Goat milk still contains lactose, so not for confirmed lactose intolerance

4. Earth's Best Organic Baby Formula — Most versatile

The only certified organic pick in this set, spanning the full 0-12 month window.

Best for: parents who want an organic cow-milk formula across the full 0-12 month window Skip it if: you specifically want a goat-milk protein source

Earth's Best is the versatile pick because it does the most jobs at once: cow-milk protein (the default for most pediatricians), certified organic sourcing, and an age range covering 0-12 months. The tin is 21 oz, weighs 1.31 lb, and measures 4.88 x 5.1 x 5.1 in, which is a near-cube that stacks well. The listing states the formula is made with organic milk from grass and grain-fed cows, contains lutein, prebiotics, DHA and ARA, and includes no added corn syrup.

Two honest caveats sit on this pick. The listing carries a 2008 release date, which is the oldest in the set by more than a decade. Formulations do get updated without a new release date, but the paper trail here is thinner than for Similac's 2023 date or Kabrita's 2024 date. And it is the slowest seller of the five in this set, which means less turnover per shelf. Between those two facts, check the tin's expiry date carefully when it arrives.

Pros:

• Only certified organic pick in this guide
• 21 oz tin, marginally more powder than Similac
• Listing states no added corn syrup
• Manufacturer states DHA, ARA, iron and prebiotics
• Mid-price band, between the goat options

Cons:

• Oldest release date in the set (2008)
• Slowest seller of the five here
• No stated no-rbGH or A2-protein claim

5. Kabrita Goat Milk Infant Formula Powder — Best premium

The largest tin in the set and the pick for newborns who struggle with cow-milk curds.

Best for: newborns who spit up on cow-milk formula and need a gentler curd Skip it if: you are not ready for the highest price position in this set

Kabrita is the most expensive pick here and the largest tin: 28 oz of powder, 1.76 lb, in a 6.25 x 5 x 5 in canister. That is roughly a third more powder per tin than Similac's or Bubs's containers, which offsets some of the price gap when you are working out how far a tin goes. The formulation is European, made in the Netherlands with goat milk from Dutch farms according to the listing, and Kabrita says the product is non-GMO with no corn syrup, antibiotics or growth hormones.

The manufacturer's case for goat milk is on the tin: "Goat milk proteins form softer curds during digestion than cow milk proteins", and the A2 protein claim on the front. Kabrita also states the formula includes DHA, ARA, iron, vitamin D, prebiotics, beta-palmitate and lactose. Against Bubs, the differences are the larger tin, the European sourcing and the higher price position. Against Similac, the difference is the protein source itself.

Pros:

• Largest tin in the set at 28 oz
• Goat-milk protein with an A2 claim on the listing
• Manufacturer states three Clean Label Project certifications
• Made in the Netherlands to European standards per the listing
• Released 2024, most recent in the set

Cons:

• Highest price position of the five picks
• Second-slowest seller of the five here
• No published organic certification on the listing

What the listings do not tell you about newborn feeding

Three things you will not find on any tin.

• Exact bottles per tin. Yield depends on how many fluid ounces per feed your baby takes, and that changes weekly in the first months.
• How well the formula agrees with your specific newborn. Every listing describes "gentle" digestion or "easy" prep. Only your baby tells you if the formula sits well, and the sign is not on the tin: it is spit-up, gas and sleep.
• Whether the tin ships with the seal intact. Two active sellers per listing is the minimum I used to screen, but it is not a guarantee. Inspect the foil seal before the first scoop.

One more thing worth naming: none of these products replaces pediatric advice on the best baby formula for newborns. If your baby has a diagnosed cow-milk protein allergy, galactosemia, or a metabolic condition, your pediatrician will point you to a specific hypoallergenic or amino-acid formula that is not in this set.

The verdict

The best baby formula for newborns in this set is Similac 360 Total Care Ready-to-Feed, and the reason is narrow and practical: it is the only pre-mixed liquid option here, and pre-mixed liquid is what a newborn parent needs at 3am in the first two weeks. Twelve 2 fl oz bottles, no water, no scoop, no shaking. The price position is entry, which is unusual for a ready-to-feed format, and that makes it a low-risk way to see if the 360 Total Care formulation works for your baby.

By week three or four, switch to the Similac 360 Total Care powder in the 20.6 oz tin. Same formulation, larger unit, dramatically better cost per feed once you factor in a newborn's rising intake. The cutoff is roughly the day your baby's daily intake crosses what a 24 fl oz pack delivers, which for most full-term newborns is somewhere in the second half of month one.

If cow-milk formula does not settle, Kabrita is the alternate. The goat-milk protein and the A2 claim on the listing give it a genuine reason to exist alongside Similac, not just a marketing angle. Bubs is the cheaper way to try goat milk if the price position on Kabrita is a stretch.

FAQ

What is the best baby formula for newborns overall?

The best baby formula for newborns in this comparison is Similac 360 Total Care Ready-to-Feed, sold as 12 pre-mixed 2 fl oz bottles. It wins the first weeks because there is no measuring, no water and no shaking involved in a feed. Move to the 20.6 oz Similac 360 Total Care powder tin once your baby's daily intake exceeds what a 24 fl oz pack delivers.

Is ready-to-feed formula worth it for a newborn?

Ready-to-feed formula is worth it for the first two to four weeks and for travel. Similac's pack gives you 12 sterile 2 fl oz bottles you cap and hand over. The catch is 24 fl oz total per pack, which does not sustain a baby approaching 24 to 32 fl oz per day. Most families pair it with a powder tin of the same formulation.

How does Similac 360 Total Care powder compare to Kabrita goat milk?

Similac 360 Total Care powder and Kabrita differ in one thing that matters: the protein. Similac uses cow milk in a 20.6 oz tin at 1.29 lb. Kabrita uses goat milk with an A2 protein claim in a 28 oz tin at 1.76 lb. Choose Similac if your newborn tolerates cow milk, and Kabrita if a cow-milk formula has caused spit-up or fussiness.

How long does a 20 oz tin of powder formula last a newborn?

How long a 20 oz tin lasts depends on your baby's daily intake, which climbs from a few fluid ounces per feed in week one to 24 to 32 fl oz per day by the end of month one. The listings do not publish a bottles-per-tin figure. As a planning rule, expect a 20 to 21 oz tin to cover a handful of days once a newborn is fully feeding.

What should I avoid when choosing the best baby formula for newborns?

Avoid formulas without a clearly stated age range: every product in this guide is labelled 0-12 months on the manufacturer's listing. Avoid switching brands repeatedly in the first month, because that is when digestion is most sensitive. And avoid buying only ready-to-feed, or only powder, in the first month: the two formats solve different problems and most families need both.

Start with a single pack of the ready-to-feed Similac 360 Total Care to get through the first ten days without the mixing routine, then order the powder tin in the same formulation for month two onward. If cow-milk formula unsettles your baby, Kabrita is the alternate worth trying next, with Bubs as the entry-priced way to test the goat-milk protein before committing to the larger 28 oz tin. Read the age range on any tin before you buy, check the expiry date when it arrives, and take everything on this page as a shortlist to bring to your pediatrician, not a substitute for one.
