You're here, so you already know that choosing a formula for your baby is overwhelming. Whole milk or nonfat milk as a base? What can I trust to be safe and free from heavy metals and contaminants? Which brands are actually closest to breast milk? And most standard US formulas rely heavily on skim milk and vegetable oils - far from the nutrient-dense composition of breast milk. That’s why many parents choose whole milk-based formulas, which are closer to breast milk's natural fat profile. We enlisted the help of Pediatric Dietitian Susan Okonkowski (RDN, MPH) to help us understand what actually matters when choosing a formula.

‍

Combining Okonkowski's expertise with hands-on testing by Motherful moms on staff, we evaluated the three leading organic whole milk infant formulas: Little Spoon Organic Whole Milk Infant Formula, Kendamil Organic Infant Formula, and Bobbie Organic Whole Milk Formula on: ingredients & formulation, safety & third-party testing, and consistency & scent. Read on to find out which wins!

Should I Use Formula?

Moms often wrestle with the decision to formula or combo feed.

‍

"Breastmilk is an incredible, complete source of nutrition for babies, but it's not always possible for every mother to breastfeed." says Okonkowski. Medical conditions, medication, milk supply, and lifestyle requirements are all reasons mothers choose formula.

‍

But that doesn’t make formula feeding a compromise. "With the right education, moms can choose a high-quality formula that resembles breast milk to help their baby get the nutrients they need.”

‍

The most important factors? A formula that resembles breast milk, is transparent about safety and testing results, and is affordable. How do our three brands compare?

Top Organic Whole Milk Formulas, Compared

Ingredients & Formulation: Little Spoon Wins With New Zealand Grass-Fed Whole Milk

According to Okonkowski, "parents should look for a formula that closely matches the profile and composition of breastmilk." That means:

• Protein ratio: "A 60:40 whey-to-casein ratio is ideal - it mirrors mature breastmilk and supports comfortable digestion."
• Carbohydrate source: "Look for 100% lactose, which helps with calcium absorption and promotes healthy gastrointestinal flora."
• DHA and ARA: Critical for brain and eye development.¹ "I recommend choosing a formula that meets EU standards of at least 20 mg DHA per 100 kcal, ideally paired with ARA."
• Whole milk base: Whole milk formulas preserve naturally-occurring milk fat globule membrane (MFGM), which has been studied for its role in brain development and immune health.² "Standard formulas that start with a nonfat milk base and add vegetable oils to reach the required fat content do not.”
• Prebiotics: Breast milk naturally contains prebiotics, but most formulas don't include them. Look for added prebiotics like fructo-oligosaccharides (FOS) or galacto-oligosaccharides (GOS), which aid digestion.

Here’s how each formula compares:

‍

🥇 Little Spoon Organic Whole Milk Infant Formula features the best combination of ingredients, sourcing, and nutrition: 

• Organic, grass-fed whole milk from New Zealand - where cows graze on open pasture under much stricter dairy standards than in the US or UK.³ "Milk from these cows contains a higher percentage of fat and protein when compared to US farm milk averages," says Okonkowski. "Grass-fed cow's milk also tends to be higher in omega-3 fatty acids, beta-carotene, and heart-healthy fatty acids.”⁴
• 60:40 whey-to-casein ratio modeled after mature breast milk for easy digestion.
• 100% lactose as the sole carbohydrate source - no corn syrup, glucose solids, or maltodextrin.
• Plant-based DHA and ARA aligned with rigorous EU standards for brain and eye development; ARA of 34 mg is within natural breast milk range.
• Omega-6 levels within the breast milk range.
• Prebiotic FOS to support gut and immune health.‍
• Nucleotides - all 5 types naturally found in breast milk - to support immune function and gut development. ‍
• L-Carnitine to help infants convert fat into energy - an EU-mandatory nutrient that some US formulas leave out.‍
• No palm oil or corn syrup

‍

🥈 Kendamil Organic Infant Formula comes in second with a formula that checks most boxes but blends whole milk and skim milk - meaning more fat from vegetable oils:

• Blend of whole and skim milk, sourced from grass-fed cows in the UK - where cows are typically housed indoors part-time.⁵
• 60:40 whey-to-casein ratio
• GOS prebiotics
• DHA and ARA that meet EU levels - but ARA comes in around 12 mg, well below the 30-60 mg breast milk range
• Nucleotides for immune function and gut development
• No added L-Carnitine 
• No palm oil or corn syrup

❌ Bobbie Organic Whole Milk Formula is last with no added prebiotics and no nucleotides:

• Sourced from grass-fed cows in the US, where no national grass-fed standard exists and grazing requirements vary by farm.
• Organic whole milk base
• 60:40 whey-to-casein ratio
• DHA and ARA at EU requirement levels
• No prebiotics
• No nucleotides
• L-Carnitine to help infants convert fat into energy
• No palm oil or corn syrup

Safety & Third-Party Testing: Little Spoon Wins with the Most Comprehensive and Transparent Testing

Heavy metal contaminants like lead, arsenic, cadmium, and mercury have been found in baby formulas during third-party testing, and are a “critical safety concern,” says Okonkowski. These are known neurotoxins, and even small exposure can impact infant brain development. That’s why we reviewed USDA Organic and Clean Label Project certifications, and third-party safety data.

‍

🥇 Little Spoon Organic Whole Milk Infant Formula is the most transparent option of the brands we tested. It’s the only brand that publishes exact batch-level heavy metal test results - all well below strict EU and US thresholds.⁶ Little Spoon is USDA Organic and EU Organic certified, and holds the Clean Label Project Purity Award and First 1,000 Day Promise award. "Dual certification reflects stricter sourcing, further reduction of contaminant exposure, " says Okonkowski.

‍

Each batch of Little Spoon undergoes rigorous testing:

• Screening for 500+ potential toxins
• 2,000+ safety checks
• SRC testing - an indicator of hygiene controls for spore-forming bacteria - at limits 10× stricter than international guidelines.

✔️ Bobbie Organic Whole Milk Formula is USDA Organic certified and holds the Clean Label Project Purity Award. It does not publish batch-level heavy metal testing, and does not hold the more stringent EU Organic certification or the First 1,000 Day Promise award.

‍

Each batch of Bobbie undergoes the following testing:

• 2,000+ safety checks
• SRC testing

‍

❌ Kendamil Organic Infant Formula is both USDA Organic and EU Organic certified and is Clean Label Project certified. It does not publish batch-level heavy metal data or specific safety test information, and it does not hold the First 1,000 Day Promise award.

‍

Kendamil does not publish any information on the number of toxin screenings or safety checks, and conducts no SRC screening.

‍

In February 2026, two batches of Kendamil were recalled due to the presence of cereulide toxin, which causes vomiting and gastrointestinal upset.⁷

Consistency and Scent: Little Spoon & Bobbie Tie

Clumpy or foamy formula can make bottles harder to prepare and less appealing for babies. Our editor tested all three with her 3-month-old Liam - here's how they compared:

‍

🥇 Little Spoon & Bobbie both mix evenly with no clumping and minimal foam, and were accepted by Liam without fuss. Little Spoon mixes to a creamy, smooth consistency with a mild, buttery scent. Bobbie is equally smooth with a lightly sweet scent.

❌ Kendamil Organic Infant Formula is a coarser powder that clumps and sticks to the sides of a bottle, making feeding preparation more difficult. Our editor noted an off-putting metallic scent.

Our Verdict: Little Spoon is the Best Organic Whole Milk Infant Formula

Little Spoon Organic Whole Milk Infant Formula is our Pediatric Dietitian's #1 choice.

‍

With the best ingredients, including 100% grass-fed organic whole milk from New Zealand, comprehensive and transparent safety testing, and a winning mixability, it's the clear winner on ingredients, safety standards, and consistency.

‍

Pediatric Dietitian Susan Okonkowski agrees: "I recommend Little Spoon for growing babies. It meets a high standard across both sourcing quality and safety verification."
