A Balanced Guide to Choosing Baby Formula

One thing we aren’t going to do is lose sleep over baby formula. There is no such thing as a perfect formula, because we don’t live in a perfect world. 

The reality is that infant formula is designed to nourish babies when breastfeeding is not possible or not preferred. Breastmilk is considered the biological standard, but formula exists to safely meet nutritional needs when needed. And what a wonderful thing that is!

Instead of chasing perfection, it’s more helpful to understand what ingredients are doing and decide what matters most to you. Give yourself permission and grace to make the best choice you can and let the rest go.

Whole Milk vs Nonfat Milk

Infant formulas can be made using either whole milk or nonfat (skim) milk with added fats. The difference isn’t about whether one is more “complete” than the other, but rather how the fat portion of the formula is built.

With nonfat milk formulas, manufacturers start with a kind of “blank slate” when it comes to fats. Since the natural milk fat has been removed, they build the entire fat profile using a blend of oils. This allows for a high level of control over the types and amounts of fatty acids, and helps ensure consistency from batch to batch.

With whole milk formulas, manufacturers take a different approach. They start with natural milk fat already present, which includes a mix of fatty acids along with components like cholesterol and milk fat globule membrane (MFGM). From there, they add specific oils as needed to round out the fat profile and meet infant nutrition requirements. So while oils are still used, the formula is built on a foundation of milk fat + added oils, rather than oils alone.

There are reasons a manufacturer might choose either approach. Starting with a blank slate can offer flexibility in designing the fat profile, while starting with whole milk allows the formula to retain naturally occurring dairy fat components that some brands and families value.

Whole milk formulas may feel more “food-based” to some parents, while nonfat formulas offer a more fully customized fat blend. At the end of the day, it’s simply two different formulation strategies to achieve the same goal: providing the fats babies need for growth and development. Both are precisely formulated and regulated to support infants.

Organic vs. Grass-Fed vs. “Conventional”

The terms organic and grass-fed are often used together, but they refer to different aspects of how dairy is produced. Organic refers to farming practices. Cows are fed non-GMO feed, antibiotics and growth hormones aren’t allowed, pesticide use is restricted, and cows must have some pasture access. However, organic does not mean the cows are exclusively grass-fed.

Grass-fed refers to the cow’s diet. 100% grass-fed cows eat primarily grass and forage instead of grain, which can slightly increase omega-3 levels. However, grass-fed is not the same as organic, and unless certified organic, cows may still be exposed to pesticides or antibiotics depending on farming practices.

Many are both grass-fed AND organic

Conventional dairy (non-organic, non-grass-fed) comes from cows raised under standard farming practices, often including grain-based feed.

Choosing between these options comes down to personal priorities and budget. Some parents prefer organic to limit pesticide exposure; others choose grass-fed for the diet differences (and most times you can get both in one). While many might opt for conventional due to affordability and access. While sourcing and farming methods differ, all formula must meet strict safety and nutritional standards and provide complete nutrition for infants.

Carbohydrates

Lactose is the primary carbohydrate in breastmilk. It’s made up of glucose and galactose and supports beneficial gut bacteria and calcium absorption.

Formulas that use lactose as the main carbohydrate are closest to breastmilk. However, some babies cannot tolerate standard lactose levels. In those cases, formulas use alternative carbohydrate sources.

This is where the confusion often happens.

High fructose corn syrup is NOT used in infant formula.

High fructose corn syrup is made up of a mix of glucose and fructose (typically around 55% fructose and 45% glucose), meaning more than half of it is fructose - a sugar that is not a primary component of breastmilk.

Infant formulas are designed to more closely reflect the carbohydrate profile of breastmilk. For that reason, high fructose corn syrup is NOT used in standard infant formulas.

I think what’s happening is people are confusing high fructose corn syrup and corn syrup solids/glucose syrup. They are NOT the same thing.

What some formulas do use instead are corn syrup solids or glucose syrup, which are made up of glucose (often in the form of glucose chains that are easily broken down in the body). Glucose is a simple sugar and the body’s primary fuel source.

These ingredients are used for specific functional reasons. In certain situations, like when lactose needs to be reduced or removed for lactose intolerances or conditions such as galactosemia where galactose cannot be properly metabolized, glucose-based carbohydrates like corn syrup solids are used because they provide readily usable energy without relying on lactose or fructose.

So while, yes, corn syrup solids may be more processed than lactose, they serve a targeted nutritional purpose and are not the same thing as high fructose corn syrup.

Seed Oils

This is one of the most misunderstood topics when it comes to baby formula.

All infant formulas use a blend of fats, often including oils like sunflower, safflower, coconut, palm, or canola oil. Breastmilk naturally contains a complex mix of fatty acids, including palmitic acid, oleic acid, linoleic acid, and alpha-linolenic acid. Because no single fat source can replicate that profile, formulas use a combination of oils to more closely match the fats found in breastmilk.

Without them, formulas would not be able to provide the fatty acids infants need. While the specific oil blends can vary between brands, the goal is the same: to deliver a nutritionally complete and balanced fat profile.

Palm oil is one many parents feel hesitant about, largely because of how it’s discussed online. Some studies suggest that a specific form (palm olein) can bind to calcium in the gut, which may lead to slightly firmer stools for some babies and a small reduction in calcium absorption.

Some formulas use structured fats like beta-palmitate (or high sn-2 palmitate/palmitic acid) to more closely mimic breastmilk and support softer stools, but both approaches are considered safe and nutritionally adequate.

Goat Milk Formula

Goat milk formula can be a helpful option for some babies who struggle with standard cow’s milk formula, as it forms a softer, looser curd that may be easier to digest.

It also has a slightly different protein structure, with more A2-type casein and less A1, which some families feel is gentler on digestion. It naturally contains certain prebiotic oligosaccharides and well-absorbed minerals, as well. 

Because of this, some babies may do better with mild issues like gas or fussiness. However, goat milk is still dairy and contains similar proteins and lactose, so it’s not appropriate for babies with cow’s milk protein allergy or those needing a lactose-free formula.

This is not an exclusive list, but a few options I  looked into when my kids were babies. 

Lactose-Free Formula: Do You Really Need It?

True lactose intolerance in infants is extremely rare and is typically genetic. Babies with this condition usually show symptoms very early on, including poor growth and signs of malabsorption. More commonly, what parents may encounter is temporary or secondary lactose intolerance, which can occur after gut irritation or inflammation.

In these situations, lactose-free or reduced-lactose formulas can sometimes help improve symptoms. However, it’s important to understand that these formulas are not “lacking” carbohydrates, they simply use alternative sources (typically glucose-based), instead of lactose. These formulations are designed for specific circumstances where lactose isn’t well tolerated, rather than as a default or superior option.

For babies with cow’s milk protein allergy (CMPA), suspected sensitivities, or more complex feeding concerns, it’s best to work with your pediatrician to choose the right formula.

Final Thoughts

At the end of the day, you have to do what you feel most comfortable with. Infant formula is highly researched and designed to safely nourish babies.

If formula is part of your journey, try not to lose sleep over choosing the “perfect” one. Choose what works best for your family, your baby, and your budget, and let that be enough.

Your energy is better spent bonding with your baby and showing up as a present. The internet can be loud, but it does NOT get to decide your worth as a parent!!
