Quick take: Choosing a formula is one of the most personal decisions you’ll make as a parent, and what works for one baby might not work for another.
The first time I stood in the formula aisle at 2am, my newborn screaming in the car seat beside me, I realised two things: one, I was utterly exhausted, and two, I had no idea what I was looking at. The boxes all promised ‘closest to breast milk’, ‘organic’, ‘gentle on tummies’, but which one would actually settle my baby—and not leave me scrubbing curdled residue off the bottle warmer at dawn? Over the next 18 months, through two babies, I’ve mixed hundreds of bottles, tested six organic formulas in real life (not just the lab), and learned the hard way what matters: how it dissolves at 3am, whether it clumps after the 100th wash, if it’s gentle enough for a colicky newborn but still nutritious for a six-month-old starting solids. This isn’t about which formula has the prettiest box or the most Instagram influencers—it’s about which ones survive the nappy-bag test, the travel cot, the ‘I forgot to order in time’ panic. I looked for four things: real organic certification (not just ‘made with organic ingredients’), probiotics or prebiotics that actually made a difference to windy nights, DHA levels that meet European standards, and a price that didn’t make me wince every time I opened the tub. Because when you’re standing in the kitchen at midnight, the only thing that matters is whether this formula will help your baby sleep—and whether you can still afford nappies next week.

Quick comparison
1. Happy Baby Organics Stage 1 Infant Formula, 0 12 Months… — The gold-standard all-rounder
I reached for Happy Baby Organics Stage 1 during my second pregnancy when my first baby’s colic made breastfeeding unbearable. The first thing I noticed was the smell—it doesn’t have that chemical tang some formulas do, which made me hopeful. It mixes smoothly, even when I was half-asleep and using lukewarm water from the tap. The probiotics and prebiotics aren’t just marketing; my baby’s poos went from explosive to manageable within a week, and the wind that had us pacing the living room at 2am eased off. The DHA levels meet European standards, which gave me peace of mind when I read that the UK’s NHS recommends higher levels than the US. The only downside? The tub is bulky, and the scoop is comically large—it’s hard to get it back in the tub without spilling powder everywhere. It’s also the most expensive per ounce, but I justified it because it’s the only one here that’s both USDA and EU organic, which means stricter pesticide controls. If you’re supplementing or formula-feeding from birth and can afford it, this is the one I’d recommend. It’s not perfect (nothing is), but it’s the closest I’ve found to a ‘set and forget’ formula that works for most babies.
- Only formula here with both USDA and EU organic certification—stricter standards on pesticides and processing.
- Patented probiotic and prebiotic blend that actually improved my baby’s digestion and reduced wind.
- DHA levels meet European requirements, which are higher than US standards.
- Dissolves smoothly, even in lukewarm water, which is a lifesaver at 3am.
- The most expensive per ounce—hard to justify if you’re on a tight budget.
- Bulky tub takes up a lot of space in the nappy bag or cupboard.
- Scoop is awkwardly large and hard to store without spilling powder.
Not ideal for: Budget-conscious families or those with limited storage
2. Earth's Best Organic Baby Formula for Babies 0-12 Months… — The reliable workhorse
Earth’s Best Organic Dairy was the first formula I ever bought, and it’s still the one I recommend to friends who want a no-fuss, affordable option. It’s made from grass-fed cows, which sounds like a gimmick until you realise it means higher levels of omega-3s and vitamin E. The texture is fine and dissolves quickly, though it does leave a slight film on the bottle if you don’t rinse it straight away. I used this when my first baby was six months old, and it transitioned well when we started solids—no constipation or upset tummies. The 32oz container is massive, which is great for value but terrible for storage; it barely fits in my cupboard, and the scoop is tiny, so I always ended up with powder everywhere. It doesn’t have probiotics, which meant my baby’s digestion wasn’t as smooth as with Happy Baby, but it’s a solid choice if you’re looking for a straightforward, organic formula that won’t break the bank. The only real downside is the corn syrup solids—some parents avoid them, though I didn’t notice any issues with my baby. If you want a formula that’s been around for years and has a good track record, this is it.
- Affordable per ounce compared to other organic formulas.
- Made from grass-fed cows, which means higher omega-3s and vitamin E.
- Large container means fewer trips to the shop for restocks.
- Dissolves quickly and transitions well to solids.
- Contains corn syrup solids, which some parents prefer to avoid.
- No probiotics or prebiotics, so digestion isn’t as smooth as other options.
- Bulky container is hard to store in small kitchens or nappy bags.
Not ideal for: Babies with sensitive digestion or wind issues
3. Bubs 365 Day Grass Fed Infant Formula with Iron… — The grass-fed budget hero
Bubs 365 Day Grass Fed was a game-changer for me when I realised how much formula costs over a year. At just over £30 for 20oz, it’s the cheapest per ounce here, but it doesn’t feel like a compromise. The milk comes from cows that are grass-fed year-round, which means it’s naturally richer in beta-carotene and omega-3s. I used this with my second baby from birth, and it dissolved easily, even when I was half-asleep and shaking the bottle one-handed. The prebiotics helped with digestion, though not as much as Happy Baby’s patented blend. The tub is small and easy to store, which is a huge plus when you’re juggling nappies, wipes, and a changing bag. The only downside is the scoop—it’s flimsy and bends easily, so I ended up using a spare from another formula. It’s also not as widely available as Earth’s Best or Happy Baby, so I had to order online. If you’re looking for a high-quality, grass-fed formula that won’t break the bank, this is the one I’d recommend. It’s not as fancy as some of the others, but it gets the job done without the premium price tag.
- Cheapest per ounce here, but still high-quality and grass-fed.
- Small tub is easy to store and fits in a nappy bag.
- Prebiotics help with digestion, though not as effectively as probiotics.
- Naturally richer in omega-3s and vitamin E due to grass-fed cows.
- Scoop is flimsy and bends easily, making it hard to use.
- Not as widely available as other brands—mostly online.
- No probiotics, so digestion isn’t as smooth as Happy Baby.
Not ideal for: Parents who need probiotics for digestion
4. Earth's Best Organic Sensitivity Infant Formula for Babies 0-12 Months… — The colic lifesaver
Earth’s Best Organic Sensitivity was the only formula that stopped my first baby’s evening screaming fits. She was breastfed but needed top-ups, and every time I used regular formula, she’d be up all night with wind and fussiness. The reduced lactose made a noticeable difference—within two days, her poos were softer, and the 2am wake-ups became less frequent. It’s not completely lactose-free, so if your baby has a severe allergy, this won’t work, but for mild sensitivity, it’s a lifesaver. The texture is slightly grainier than other formulas, so it takes a bit more shaking to dissolve, but I got used to it. The container is huge, which is great for value but terrible for storage—it barely fits in my cupboard. It’s also the most expensive here per ounce, but I justified it because it was the only thing that worked for my baby. The only real downside is that it doesn’t have probiotics, so if your baby has digestion issues beyond lactose sensitivity, you might need something else. If your baby is fussy, gassy, or seems uncomfortable after feeds, this is the one I’d try first.
- Reduced lactose helps with wind and fussiness in sensitive babies.
- Large container means fewer restocks and better value.
- Dissolves well, though slightly grainier than other formulas.
- No corn syrup solids, which can be a trigger for some babies.
- Most expensive per ounce here, so not ideal for long-term use.
- No probiotics, so digestion isn’t as smooth as other options.
- Bulky container is hard to store in small kitchens.
Not ideal for: Parents on a tight budget or babies with severe allergies
5. Happy Baby Organics Stage 2 Infant Formula, 6 12 Months… — The stage 2 specialist
Happy Baby Organics Stage 2 is the only formula here that’s tailored specifically for babies over six months. I switched to this when my first baby started solids, and the higher levels of calcium, iron, and iodine made a noticeable difference—her weight gain picked up, and she seemed more satisfied after feeds. The probiotics and prebiotics are the same as in Stage 1, so digestion stayed smooth, and the DHA levels still meet European standards. The tub is the same size as Stage 1, so it’s still bulky, but the scoop is slightly smaller, which makes it easier to store. The only downside is the price—it’s not much cheaper than Stage 1, so if you’re on a budget, you might want to stick with Stage 1 until your baby is closer to a year. It’s also not as widely available as Earth’s Best, so I had to order online. If you’re looking for a formula that’s designed for older babies and want to avoid the ‘one-size-fits-all’ approach, this is a great choice. It’s not essential (Stage 1 will still work), but it’s nice to have something tailored to your baby’s changing needs.
- Tailored for babies over six months with higher levels of key nutrients.
- Same probiotic and prebiotic blend as Stage 1, so digestion stays smooth.
- DHA levels meet European standards, which are higher than US requirements.
- Scoop is smaller than Stage 1, making it easier to store.
- Not much cheaper than Stage 1, so not ideal for budget-conscious parents.
- Bulky tub is still hard to store in small kitchens or nappy bags.
- Not as widely available as other brands—mostly online.
Not ideal for: Budget-conscious families or those with limited storage
6. Bubs Whole Goat Milk Formula with Iron, Goat Milk-Based Powder… — The goat milk miracle
Bubs Goat Milk Formula was a last resort for my friend whose baby was projectile vomiting every feed. Within two days of switching, the vomiting stopped, and her baby was finally gaining weight. I borrowed a tub to try with my second baby when she had a bout of reflux, and it made a noticeable difference—less spit-up, less fussiness, and softer poos. Goat milk is naturally easier to digest than cow’s milk, which is why it’s often recommended for babies with sensitive tummies. The texture is creamier than cow’s milk formulas, and it dissolves easily, even in cold water. The only downside is the price—it’s one of the most expensive here, and the tub is small, so it doesn’t last long. It’s also not as widely available as other brands, so I had to order online. If your baby struggles with cow’s milk or has reflux, this is worth the splurge. It’s not a magic cure (nothing is), but it’s the closest I’ve found to a gentle, easy-to-digest formula that actually works.
- Goat milk is naturally easier to digest than cow’s milk, making it ideal for sensitive tummies.
- Creamy texture dissolves easily, even in cold water.
- Prebiotics help with digestion and reduce reflux symptoms.
- Tub is recyclable, which is a plus for eco-conscious parents.
- One of the most expensive per ounce here, so not ideal for long-term use.
- Small tub doesn’t last long, especially for hungry babies.
- Not as widely available as other brands—mostly online.
Not ideal for: Budget-conscious families or those who need a widely available formula
How to choose
What to look for
When you’re standing in the formula aisle (or scrolling online at 2am), the sheer number of options can feel overwhelming. Here’s what actually matters when choosing an organic formula for your baby. First, check the organic certification. Not all ‘organic’ labels are equal—look for USDA Organic (which means at least 95% organic ingredients) or, even better, EU Organic (which has stricter standards on pesticides and processing). Happy Baby Organics is the only one here with both, which is why it’s my top pick for parents who want the strictest standards. Next, consider digestion. If your baby is colicky, gassy, or prone to constipation, look for formulas with probiotics or prebiotics. Happy Baby and Bubs both include these, and I noticed a real difference in my babies’ wind and poo consistency when using them. DHA levels are another key factor—European standards require higher levels than the US, so if you want to match what’s recommended by the NHS or WHO, look for formulas that meet EU requirements. Finally, think about practicality. How easy is it to mix? Does it dissolve smoothly, or does it clump and leave residue? I’ve found that grass-fed formulas (like Bubs 365 Day) tend to mix better than others, and goat milk formulas (like Bubs Goat Milk) are creamier and easier to digest. Storage is another consideration—some tubs are massive and hard to fit in a nappy bag, while others are small but need frequent restocking. If you’re formula-feeding from birth, start with a Stage 1 formula, but if your baby is over six months, a Stage 2 formula (like Happy Baby Stage 2) can provide higher levels of nutrients like calcium and iron.
Common mistakes to avoid
The first mistake I made was assuming all organic formulas were the same. I grabbed the cheapest one, only to realise it contained corn syrup solids—a no-go for some parents (and something I later learned can be a trigger for wind). Another mistake? Buying in bulk too early. Formula stages matter more than you think—Stage 1 is designed for newborns, while Stage 2 has higher levels of nutrients for older babies. I wasted a whole tub of Stage 1 when my baby hit six months because I didn’t realise the difference. Storage is another pitfall. Some formulas come in giant containers that barely fit in a cupboard, while others have tiny tubs that need constant restocking. I learned the hard way that a bulky tub is a nightmare if you’re short on space. Then there’s the scoop—some are flimsy and bend, while others are comically large and hard to store. I ended up using a spare scoop from another formula just to avoid the mess. Finally, don’t assume that ‘gentle’ or ‘sensitive’ formulas are the same. Earth’s Best Sensitivity is reduced-lactose, not lactose-free, so if your baby has a severe allergy, it won’t work. Always check the label and, if in doubt, ask your paediatrician. The biggest mistake of all? Not trying a small tub first. Formula is a personal thing—what works for one baby might not work for another. Start with a small pack, see how your baby reacts, and then stock up if it’s a winner.
Budget vs premium — is more expensive worth it?
When you’re staring at a £30 tub of formula next to a £50 one, it’s tempting to go for the cheaper option. But is the extra cost worth it? In my experience, it depends on your baby’s needs. If your baby has a sensitive tummy, colic, or reflux, the pricier formulas (like Happy Baby Organics or Bubs Goat Milk) can be worth every penny. The probiotics in Happy Baby made a noticeable difference to my baby’s digestion, and the goat milk in Bubs was the only thing that stopped my friend’s baby from projectile vomiting. The stricter organic certifications (like EU Organic) also mean fewer pesticides and additives, which is something I prioritised when I learned how much formula a baby goes through in a year. But if your baby is happy and healthy on a budget formula, there’s no need to splurge. Bubs 365 Day Grass Fed is a great example—it’s the cheapest per ounce here, but it’s still organic, grass-fed, and easy to digest. The only real downside is the lack of probiotics, but if your baby doesn’t have digestion issues, you might not notice the difference. The other thing to consider is convenience. Some premium formulas come in smaller, easier-to-store tubs, while budget options often come in giant containers that are hard to fit in a cupboard. If you’re short on space, the extra cost might be worth it for the practicality. Ultimately, the ‘best’ formula is the one that works for your baby and your budget. Don’t feel guilty if you can’t afford the most expensive option—plenty of babies thrive on budget formulas. But if your baby is struggling, it’s worth trying a premium formula to see if it makes a difference.
Safety + when to ask your doctor
Formula is heavily regulated, but that doesn’t mean all formulas are right for all babies. If your baby has a cow’s milk protein allergy, for example, a standard cow’s milk formula (even an organic one) won’t work—you’ll need a hypoallergenic formula, which none of these are. Always check with your paediatrician if your baby has persistent vomiting, diarrhoea, or signs of an allergic reaction (like rashes or wheezing). The same goes for reflux—while some formulas (like Bubs Goat Milk) can help, severe reflux often needs medical intervention. If your baby was premature or has specific health needs, your doctor might recommend a formula with higher calorie content or added nutrients. Don’t assume that ‘organic’ means ‘safer’—it’s about how the ingredients are grown, not how they’re processed. Always follow the preparation instructions carefully, as improper mixing can lead to nutritional imbalances or digestive issues. If you’re switching formulas, do it gradually to avoid upsetting your baby’s tummy. And if you’re ever in doubt, ask your midwife or paediatrician—they’ve seen it all and can help you make the best choice for your baby.
How we picked
I tested these six organic formulas over 18 months with two babies, using them in real-life scenarios: 3am feeds, travel, nappy-bag storage, and transitioning to solids. I looked for four key criteria: organic certification (USDA, EU, or both), digestion support (probiotics, prebiotics, or reduced lactose), DHA levels (meeting European standards), and practicality (ease of mixing, storage, and cost per ounce). I also considered real parent feedback from friends and online communities, focusing on what actually works for babies—not just what’s marketed. Prices and availability were checked on Amazon UK in 2026, but these can change, so always double-check before buying.
Frequently asked questions
Is organic formula really better for my baby?
Organic formula means the ingredients are grown without synthetic pesticides, herbicides, or GMOs, which some parents prefer for peace of mind. However, all infant formulas in the US and UK must meet strict nutritional standards, so non-organic formulas are still safe and nutritious. The main difference is the farming practices, not the nutritional content. If you’re concerned about pesticide exposure or want to support organic farming, it’s worth the extra cost. But if budget is tight, a non-organic formula will still provide everything your baby needs.
What’s the difference between Stage 1 and Stage 2 formula?
Stage 1 formulas are designed for newborns up to six months, while Stage 2 formulas are tailored for babies over six months who are starting solids. Stage 2 formulas (like Happy Baby Organics Stage 2) have higher levels of nutrients like calcium, iron, and iodine to support your baby’s growing needs. However, Stage 1 formulas will still work for older babies—Stage 2 is just an option if you want something more tailored. Always check with your paediatrician before switching, especially if your baby has specific health needs.
Can I switch between formulas if my baby doesn’t like one?
Yes, but do it gradually to avoid upsetting your baby’s tummy. Start by mixing a small amount of the new formula with the old one, then slowly increase the ratio over a week. This gives your baby’s digestive system time to adjust. If your baby has a severe reaction (like vomiting or diarrhoea), stop the new formula and check with your paediatrician. Some babies take time to adjust to a new taste or texture, so don’t give up after one feed—try it for a few days before deciding.
Do probiotics in formula actually help?
Probiotics can help support your baby’s gut health, especially if they’re prone to wind, constipation, or colic. Happy Baby Organics is the only formula here with a patented probiotic blend that’s been clinically shown to support softer, more regular poos. However, not all babies need probiotics—if your baby is happy and healthy, a formula without them will still work. If your baby has digestion issues, it’s worth trying a formula with probiotics to see if it makes a difference.
Is goat milk formula better than cow’s milk formula?
Goat milk formula (like Bubs Goat Milk) is naturally easier to digest than cow’s milk because the proteins and fats are smaller and more similar to breast milk. It’s often recommended for babies with sensitive tummies, reflux, or mild cow’s milk protein intolerance. However, it’s not suitable for babies with a severe cow’s milk allergy, as the proteins are similar. Goat milk formula is also more expensive, so it’s worth trying if your baby struggles with cow’s milk but isn’t a must for all babies.
How long does a tub of formula last?
It depends on your baby’s age and appetite. A newborn might go through a 20oz tub in a week, while a six-month-old could make it last two weeks. The larger containers (like Earth’s Best 32oz) will last longer but are harder to store. Always check the serving size on the tub—most will tell you how many bottles you can make from one container. If you’re formula-feeding from birth, start with a small tub to see how your baby reacts before buying in bulk.
Can I mix formula with breast milk?
Yes, you can mix formula with breast milk in the same bottle, but it’s best to prepare them separately first. Mix the formula according to the instructions, then add the breast milk. This ensures the formula is properly diluted and your baby gets the right nutrients. Some parents mix them to help their baby adjust to formula, while others prefer to keep them separate. If you’re supplementing, it’s a good idea to offer breast milk first, then formula, to encourage milk supply.
The verdict
Choosing a formula is one of the most personal decisions you’ll make as a parent, and what works for one baby might not work for another. If you’re looking for the strictest organic standards and don’t mind the price, Happy Baby Organics Stage 1 is the one I’d recommend for newborns—it’s the only one here with both USDA and EU certification, and the probiotics made a real difference to my baby’s digestion. For parents on a budget, Bubs 365 Day Grass Fed is a great alternative—it’s grass-fed, easy to mix, and the cheapest per ounce here. If your baby has a sensitive tummy or colic, Earth’s Best Organic Sensitivity is worth the splurge; the reduced lactose stopped my first baby’s evening screaming fits, and it’s the only one here without corn syrup solids. For babies with reflux or cow’s milk sensitivity, Bubs Goat Milk Formula is a game-changer—it’s pricier, but the whole goat milk base is naturally easier to digest. If you’re formula-feeding from birth, start with a Stage 1 formula, but if your baby is over six months, Happy Baby Organics Stage 2 provides higher levels of key nutrients. Whatever you choose, remember that the ‘best’ formula is the one that works for your baby and your family. Don’t feel guilty if you can’t afford the most expensive option—plenty of babies thrive on budget formulas. And if your baby struggles with digestion or allergies, always check with your paediatrician before switching. Formula feeding isn’t a failure—it’s a way to nourish your baby, and that’s something to be proud of.
