Our Picks at a Glance
How To Choose The Best Baby Formula Closest To Breastmilk
Breastmilk changes over time to meet your baby’s needs, so the closest formula match is the one that mirrors its key nutrients and is gentle on digestion. You don’t need a degree in nutrition to read a label — you just need to know which ingredients matter most.
Lactose is the benchmark
The primary carbohydrate in breastmilk is lactose. When a formula lists lactose as its main sugar source rather than corn syrup, maltodextrin, or sucrose, it is structurally closer to what your baby would get from the breast. If your baby tolerates lactose well, this is the ingredient to look for first.
Prebiotics and probiotics for the gut
Prebiotics feed the good bacteria in your baby’s gut, while probiotics are the live beneficial bacteria themselves. Together they help support a digestive system that behaves more like a breastfed baby’s — which usually means softer, more regular poops and less gas.
Know your formula type
A standard milk-based formula suits most babies. A gentle version uses smaller, partially broken-down proteins and often reduced lactose for fussiness and gas. A hypoallergenic formula has proteins broken into tiny pieces for babies with cow’s milk allergies or colic. And organic means the milk comes from farms that meet strict standards — but organic is not the same as gentle.

In-Depth Reviews
1. Bubs Essential Infant Formula
Our pick — over 4.5★ from 400+ verified ratings; the strongest balance of quality and price.
The clean-ingredient Australian brand that colicky babies finally settle on.
Bubs Essential is the pick when you want whole cow’s milk goodness without a long list of additives. It is made in Australia with non-GMO milk and carries the Clean Label Project Award, so the ingredient list has been scrutinized for hidden junk — no GMOs, corn syrup, artificial colors, flavors, or preservatives. On top of that, it includes prebiotics and probiotics plus plant-based DHA and ARA, which together help support both tummy comfort and immune health during the first 12 months.
What wins people over is the digestive calm. Families dealing with reflux and colic report this is the only formula that helped, and babies who struggled with other brands take to it without gas or spit-up issues. Buyers who use it to supplement breastfeeding say their babies never had tummy troubles — the powder itself feels “thin,” but it packs all the nutrients needed at a price that is hard to argue with. Since it comes as a 20 oz can, it is a practical size for a daily bottle or two.
The honest caveat: opinions split on whether babies actually enjoy the taste, and a few owners note their babies spit up a bit more with it. If your little one is extremely picky about flavor, this may take some trial. But for the vast majority, the gentle digestion and clean sourcing make it the closest thing to breastmilk comfort on this list.
Clean-label calm: the whole-milk base and dual pre/probiotic support is the reason reflux-prone babies settle here.
Watch for: taste preference is genuinely mixed — some babies love it, others turn their nose up.
Reach for this if: you want the cleanest ingredients and a formula that is famously gentle on colicky, reflux-prone tummies.
Look elsewhere if: your baby is extremely sensitive to taste changes and needs a flavor they already know.
2. Similac Organic Infant Formula
The hospital-trusted brand that models its organic tub directly after breast milk.
Similac Organic is the option when you want a name you already trust from the hospital nursery, but in a USDA-certified organic form. It is explicitly “modeled after breast milk” and leaves out artificial growth hormones, palm olein oil, and corn syrup, staying non-GMO. The brain and eye development angle comes from DHA, lutein, and vitamin E — components also found in breastmilk — so you get that reassuring nutrient trio in every scoop.
The digestibility story here is strong. Buyers report babies who struggled with other Similac lines — like the 360 — improved noticeably once they switched, with better poop consistency and fewer tummy problems. A 20.6 oz tub makes it slightly larger than the Bobbie can while carrying that recognizable Abbott name. Buyers also love the practical detail that the scoop stores neatly inside the lid, keeping it cleaner and out of the powder.
The trade-off is that it is a smaller tub than some budget options while sitting at a similar price point, so the cost per bottle runs a bit higher. It is also not marketed as a “gentle” formula for gas or fussiness — it is standard organic nutrition. Choose it when your priority is trusted organic nutrition with easy digestion, not targeted relief for colic.
Trusted Organic Nutrition
- USDA-certified organic and non-GMO with no corn syrup
- DHA, lutein, and vitamin E for brain and eye development
- Scoop stores in the lid to stay clean
Know Before You Buy
- Standard nutrition, not a targeted gas or fussiness formula
- Smaller tub than several budget rivals at a similar cost
Best for: families who want a hospital-familiar brand in certified organic form with easy digestion.
Not for: babies with severe gas or colic who need a specialized gentle or hypoallergenic blend.
3. Bobbie Organic Gentle Baby Formula
The gassy-baby fix with 100% lactose — just like actual breast milk.
Bobbie Gentle stands out because its carbohydrate source is 100% lactose, matching the primary sugar in breastmilk, while skipping corn syrup, maltodextrin, and sucrose entirely. It uses smaller, broken-down milk proteins to support digestion, which is exactly what a fussy, gassy baby needs. The certification list is serious too: USDA organic, EU organic, and Clean Label Project certified, with every batch passing more than 2,000 quality checks.
Owners mention this is the formula that resolved months of severe gas after switching from brands like Similac Total Comfort, with babies burping easier and passing gas more freely. It is a favorite for combo feeding — families giving one formula bottle a day alongside breastmilk love that it sits so gently on tiny tummies. The honest notes: the scent draws mixed reactions, and some parents find the scoop hard to retrieve from the can. At 14.1 oz it is also a smaller container, so it runs out faster than bigger budget tins.
Compared to Bubs above, Bobbie is more explicit about its breastmilk-matching carbohydrate profile, while Bubs leans on its whole-milk farm story. If your baby’s main issue is gas and you want that lactose-first design, Bobbie is the sharper match — just budget for the smaller tin.
Breastmilk-Matched Sugar
- 100% lactose as the carbohydrate, no corn syrup or maltodextrin
- Smaller proteins to ease gas, fussiness, and tears
- USDA + EU organic and Clean Label Project certified
Small Quirks
- Scent is polarizing — some parents find it unpleasant
- Scoop can be hard to fish out; 14.1 oz tin is small
Choose it for: a gassy, fussy baby who needs a lactose-first, low-corn-syrup formula that mirrors breastmilk’s sugar profile.
Think twice if: you need the largest possible tin per dollar, since this is one of the smaller cans here.
4. HAPPY BABY Stage 1 A2 Organic Infant Formula
The only USDA organic formula that tailors its nutrients as your baby grows — made in Europe.
The real-world feedback is about spit-up and tummy relief. Babies who puked everything up with other brands kept it down here, and owners describe dramatically reduced spit-up along with less gas — often saying no gas drops were needed after the switch. It is also a good alternative for lactose-intolerant babies. The A2 protein structure is gentler, and the European manufacturing standard is a selling point for parents who prefer EU-style formula regulation.
Value for money is where opinions split — some parents find it pricey for the tub, while others say keeping the bottle down is worth every extra dollar. At 22.9 oz it is one of the larger organic cans in this lineup, which helps soften the per-feed cost. If your baby’s issue is spit-up and you want European-made organic with a strong gut-health story, this is the standout.
Gut-first design: the patented pre/probiotic blend is the reason babies get softer poops and less spit-up.
Price check: the main debate among owners is whether the premium is worth it — most say yes once the bottle stays down.
Reach for this if: your baby’s main struggles are spit-up and tummy discomfort and you want European-made, EU-certified organic.
Look elsewhere if: you need the lowest cost per ounce, since this sits at the premium end of the organic options.
5. Mama Bear Advantage Premium Baby Formula Powder
Amazon’s answer to name brands — double the HMOs at a fraction of the cost.
Mama Bear Advantage is the budget-savvy pick that doesn’t skimp on the breastmilk-closeness science. It is enhanced with dual HMOs — 2′-FL and LNnT — which are immune-supporting prebiotics commonly found in breastmilk, and it’s crafted to be closer to breastmilk than the brand’s previous formula. The makers say it compares to the nutrition of Similac Pro-Advance, and it brings DHA, lutein, vitamin E, and choline for brain and eye development. It is non-GMO with no artificial growth hormones or palm olein oil.
Families love this as a genuine alternative to big-name brands, with babies taking to it without colic, gas, or constipation issues — many made the switch from Similac in the first few weeks with zero digestive drama. At 34 oz it is a big, value-sized tub that feeds a baby for a long stretch, and it is even SNAP eligible. The recurring gripe is foaming: several customers note the powder creates a lot of foam when mixed, so you may need to let the bottle settle before feeding.
Unlike Bobbie or Happy Baby above, this is not organic and not a gentle formula — it is standard milk-based nutrition with a breastmilk-inspired HMO boost. If you want the closest-to-breastmilk prebiotic science without paying a premium, this delivers the best value per bottle in the whole lineup.
Breastmilk Science, Fair Price
- Dual HMOs (2′-FL and LNnT) for immune and digestive support
- 34 oz tub is one of the biggest values here
- Babies switch over smoothly from Similac
The Foam Factor
- Creates noticeable foam when mixing — needs settling time
- Not organic and not a targeted gentle formula
Best for: budget-focused families who want breastmilk-inspired HMO prebiotics in a big, affordable tub.
Not ideal if: you need organic certification or a formula specifically for gas and fussiness.
6. Bobbie Organic Combo Feeding Kit
The starter kit for parents splitting feedings between breast and bottle.
If you’re combining breastmilk and formula, Bobbie’s Combo Feeding Kit covers both. It pairs a 14.1 oz can of Organic Original Infant Formula with Organic Vitamin D Drops (0.3 fl oz), so your exclusively breastfed baby can still get the daily 400 IU of vitamin D that the American Association of Pediatrics recommends for infants under one year. The formula is designed to mimic breastmilk, with high levels of DHA (an omega-3 fatty acid for brain development) and iron, plus choline and vitamin D.
The catch is value — this kit runs fuller in price than a single formula tin, and families using it as a baby’s full diet find it adds up fast. It is designed as a supplement or top-up, not a bulk-feeding solution. If you are breastfeeding most of the time and just want a trusted organic bottle plus the vitamin D your pediatrician wants, this two-in-one kit removes the guesswork.
Two-in-one simplicity: the 400 IU vitamin D drops plus organic formula cover both halves of combo feeding in one box.
Cost reality: this is a supplement kit, not a full-diet economy — use it for top-ups, not bulk feeds.
Reach for this if: you are breastfeeding and formula feeding and want organic formula plus the pediatrician-recommended 400 IU of vitamin D.
Look elsewhere if: formula is your baby’s main food source — the 14.1 oz tin runs out quickly.
7. Mama Bear Gentle Premium Baby Formula Powder
A gentler, budget-friendly twin to Enfamil NeuroPro Gentlease.
Mama Bear Gentle is the budget pick for parents of fussy, gassy babies who want relief without the name-brand price tag. It targets fussiness, crying, and gas with partially hydrolyzed whey protein — these are smaller, broken-down proteins that are gentler on a baby’s stomach — and it cuts lactose down to just 20 percent of what’s in a standard full-lactose formula. You also get DHA for brain support and the Immune Blend 6, a mix that includes 2′-FL HMO (a prebiotic that supports gut health), vitamin C, vitamin E, and selenium.
Reviewers point out that switching from brands like Similac is smooth — babies accept it right away with no digestive changes. The gentle formula cuts down gas and fussiness, mixes easily, and the 33.2 oz can is a big-value size that lasts. The makers say it matches the nutrition of Enfamil NeuroPro Gentlease, and reviewers agree — several parents who switched noticed little difference except in their wallet.
The honest notes: it is not organic, and sensitivity and gas tolerance get mixed feedback across owners, so results vary baby to baby. Some parents also wish it were sold in stores rather than online-only. If you want gentle-formula science — reduced lactose, broken-down proteins, HMO immune support — without the premium tag, this is the pick.
Gentle Science, Fair Price
- Partially hydrolyzed whey protein for easy digestion
- Reduced lactose at 20% of routine formula
- 33.2 oz value size; babies switch over smoothly
Mixed Results
- Gas tolerance varies — not every baby gets full relief
- Not organic; online-only availability in some regions
Choose it for: a fussy, gassy baby when you want gentle-formula features — reduced lactose, hydrolyzed protein — at a budget-friendly price.
Think twice if: your baby needs organic ingredients or has a sensitivity that demands a hypoallergenic formula.
8. Enfamil NeuroPro Gentlease Baby Formula
The pediatrician-favorite that eases fussiness, gas, and spit-up in 24 hours.
Enfamil NeuroPro Gentlease makes a bold, specific promise: designed to reduce fussiness, crying, gas, and spit-up in just 24 hours. It uses smaller, broken-down proteins for sensitive tummies, a patented prebiotic blend of PDX and GOS to support softer, more regular stools, and the NeuroPro nutrition of DHA and choline for brain support. It rounds out with HuMO6, a gentle and immune blend of essential vitamins and minerals.
The results are fast and visible for many families. Parents of babies born small — under 5 pounds — found it the easiest on tiny bellies, and within a day it cut gas issues to the point where babies stopped crying in discomfort. The spit-up feedback is especially strong: babies who were spitting up constantly with the standard Enfamil yellow can settled down noticeably after the switch. The 35.2 oz size is a solid value, and buying it in bulk saves money for families who know it works.
One notable caveat: if you use a Baby Brezza baby formula machine, owners warn this powder can cake up inside the machine pretty significantly. It is also not organic. Compared to Mama Bear Gentle above, Enfamil is the trusted pediatrician-backed name with faster, more proven relief — you pay more for that certainty. If spit-up and gas are your baby’s main battles and you want a brand pediatricians know, this is the heavy hitter.
24-Hour Relief
- Designed to reduce fussiness, gas, and spit-up within 24 hours
- PDX & GOS prebiotics for softer, more regular stools
- DHA and choline for brain development
Before You Buy
- Can cake up inside a Baby Brezza formula machine
- Not organic; premium price point
Best for: families fighting visible gas, reflux, and spit-up who want pediatrician-trusted relief in about a day.
Not for: parents who require organic certification or use a Baby Brezza machine heavily.
9. Similac Alimentum with 2′-FL HMO
The allergy-specific formula that starts calming colic within 24 hours.
Similac Alimentum is the medical-grade answer for babies with cow’s milk protein allergy (CMPA) or colic tied to protein sensitivity. Its milk protein is broken down into tiny pieces to virtually eliminate allergic reactions in most babies allergic to cow’s milk protein, and it is designed to start reducing colic symptoms within 24 hours. It is the first and only hypoallergenic formula with 2′-FL HMO, an immune-nourishing ingredient.
For families dealing with CMPA (cow’s milk protein allergy), this is described as a lifesaver — it’s very gentle on sensitive stomachs, and babies tolerate it well even when they struggle with other formulas. It gives you confidence that your baby gets proper nutrients while allergens are handled. This 19.8-oz value can comes as a pack of 4, totaling 79.2 oz — the most formula on this list by far, ideal for families who know this is the one.
Allergy powerhouse: the tiny broken-down proteins plus 2′-FL HMO make it the pick for CMPA and protein-sensitivity colic.
Honest costs: strong smell, polarizing taste, and the highest price tag — you accept these for the allergy relief.
Reach for this if: your baby has a diagnosed cow’s milk protein allergy, severe colic, or lactose sensitivity that standard formulas can’t handle.
Look elsewhere if: your baby doesn’t have an allergy — the strong taste and premium price aren’t worth it for routine feeding.
Understanding the Specs
Lactose vs. Corn Syrup
Lactose is the primary carbohydrate in breastmilk, so formulas that use it as the main sugar are structurally closer to the real thing. When you see corn syrup, maltodextrin, or sucrose on the label instead, the formula is further from breastmilk’s natural sugar profile. This matters most for babies who tolerate lactose well.
Prebiotics, Probiotics, and HMOs
Prebiotics feed the good bacteria in a baby’s gut, and probiotics are the live beneficial bacteria themselves. HMOs — human milk oligosaccharides — are prebiotics naturally found in breastmilk that support immune health. A formula with these ingredients tends to produce softer, more regular poops and a digestive system that behaves more like a breastfed baby’s.
