The Truth About Baby Cereal: What Your Baby Really Needs From First Foods

It’s only been in recent history that parents have been told that baby cereal is the natural place to start when introducing solids. Anyone from your Pediatricians to your own parents often recommend:

A little rice cereal mixed with breast milk or formula.
A spoonful before bed to help baby feel fuller.
Cereal because “that’s what babies eat.”

When we look at what a growing baby actually needs nutritionally, cereal falls short. It simply doesn’t provide the nutrient density babies need to support rapid growth and development.

First, if you’re a parent and you’ve given your baby cereal, oatmeal or other grains please know there is no judgment here. Our goal is to help parents make the next best choices for them and their babies! This isn't about judging the choices you've already made. You were likely following advice that has been passed down for generations.

In this article we’re going to dive into why cereal was recommended in the first place, and where to start instead.

Baby Cereal Is a Relatively Modern Tradition

It's easy to assume that commercial baby cereal has always been a staple of infant feeding, but it hasn't.

Parents have been feeding babies complementary foods for thousands of years, but the modern practice of relying on commercially manufactured, shelf-stable infant cereals as a standard “first food” is pretty new.

It’s honestly the same concept of adults eating cereal for breakfast. We think it’s a staple, but it actually started when big food coined the saying “breakfast is the most important meal of the day” in a marketing push to sell more cereal. Spoiler alert, it worked!

Traditional cultures used what was available to them: soft-cooked vegetables, fruits, meats, eggs, broths, porridges, fermented foods, and appropriately prepared family foods.

The idea that every baby needs a box of rice cereal as their introduction to food is much more closely tied to the modern packaged-food industry than to the way humans historically fed their babies.

Babies deserve real food rather than a special category of processed food.

The Rice Cereal Problem: Arsenic

One reason we're particularly cautious about rice cereal is arsenic.

Now, almost all foods contain this because arsenic is found in the soil. So, it’s not always a big concern. The problem is that rice has a unique ability to absorb inorganic arsenic from soil and water at higher levels than other foods. The FDA has found infant rice cereal has historically been a large source of dietary arsenic exposure for babies, which raises concerns about exposure and neurodevelopment. Especially if that’s a majority of what they’re eating.

Keep in mind This doesn't mean rice is “poison.”

It means that repeatedly feeding one food that naturally tends to accumulate more arsenic isn't the best way to nourish a baby.

The CDC now specifically recommends offering a variety of infant cereals, such as oat, barley, and multigrain, rather than relying exclusively on rice cereal to help reduce arsenic exposure.

A variety of foods in all of our diets matter!

But What About the Nutritional Value of Cereal?

Let’s put the arsenic point aside for a second. Even if that wasn’t a factor to consider, this is where I think we need to zoom out and ask, what actual nutrition are our babies getting from cereal?

Baby cereal is often promoted as a first food because it is fortified with iron. And to be fair, iron is absolutely an important nutrient for babies. As babies grow and begin eating solid foods, their need for iron increases, making iron-rich foods an important part of their diet.

But iron isn't exclusive to cereal.

As babies begin complementary foods around six months, they can get important nutrients from a wide variety of foods, including meat, eggs, fish, vegetables, fruits, dairy foods, legumes, and other appropriately prepared foods. The World Health Organization emphasizes that complementary foods should provide adequate energy, protein, and micronutrients and encourages increasing food variety as babies grow.

The bottom line is that real foods can get your baby the iron they need, in addition to other nutrients, much better than cereal.

Babies Need Nutrient-Dense Foods, Not Just Something That Fills Their Bellies

Babies have tiny stomachs. At the same time, you’ve probably noticed they grow so quickly! Their brains, nervous systems, bones, muscles, immune system, and blood supply are all developing. That means the quality of those early foods matters.

A spoonful of food shouldn't just be about filling the belly. It can also be an opportunity to provide:

Protein
Healthy fats
Iron
Zinc
Choline
Vitamin A
B vitamins
Essential fatty acids
Other naturally occurring vitamins and minerals

This is one reason we love the idea of pairing foods together like healthy fats and quality proteins rather than building a baby's diet around one processed grain:

Sweet potato + egg yolk
Avocado + chicken
Squash + beef
Full-fat yogurt + berries
Liver blended into a nourishing meal in an appropriate amount
Meat + vegetables + healthy fat

These foods don't just provide calories, they provide real nourishment.

Babies Need Healthy Fats

This is especially important because baby food conversations often become very carbohydrate-centric. Look at most of the shelves dedicated to baby food and you’ll notice they’re full of pouches, grains, and quick sugary options. Fat is not something we need to fear in a growing baby.

Instead of thinking that baby's first foods need to be low-fat, we can look for naturally nutrient-dense sources of fat that are appropriate for their age and development. Things like:

Avocado
Egg yolk
Full-fat plain yogurt or cottage cheese, when appropriate
Butter
Other whole-food sources of fat

While we love including healthy fats, babies can also benefit from carbohydrates. We just need to choose the right ones for optimal nutrition.

The goal is to stop thinking that carbohydrates, especially processed grain products, need to be the foundation of every meal. There are plenty of natural unprocessed carbohydrates that are a better whole food option.

Fresh fruit is a carbohydrate.

A sweet potato is a carbohydrate.

Squash is a carbohydrate.

Potatoes are carbohydrates.

Vegetables are a carbohydrate.

These foods also come packaged with water, fiber, vitamins, minerals, and naturally occurring plant compounds. That way better than making a highly processed powdered grain the centerpiece of a baby's diet.

“It Will Keep Baby Fuller Longer”

This is one of the biggest reasons parents are told to introduce cereal early. Maybe you've heard, “Give the baby some cereal before bed. They'll sleep longer.” Or, “Add cereal so they'll stay fuller.” Let’s be real, as a new parent a little time back while the baby is sleeping sounds like a gift! But the CDC specifically states that putting cereal or other solid foods into a baby's bottle will not make them sleep longer and can increase choking risk.

And while one randomized trial found that introducing solids earlier was associated with a small increase in infant sleep duration, that study looked at early introduction of a variety of foods, not simply adding cereal to a baby's diet, and current guidance still recommends introducing complementary foods around six months for most babies.

So if you're exhausted and someone tells you that cereal will finally get your baby to sleep through the night, I get why it sounds so tempting! You're tired. You're looking for something that works. But, feeding cereal isn't a sleep strategy and putting cereal in a bottle is not recommended.

Your Baby Deserves Real Food, Too

This is really what it comes down to for us. We don't believe babies need to eat perfectly. We don't believe every meal needs to be homemade, or even that you have to make every single puree from scratch. Obviously, we don't believe you're a bad parent if you've fed your baby cereal, either! Parenting is full of decisions, and most of us are simply doing the best we can with the information we have. We’ve come to this conclusion through our own learning journey as parents.

Just like you, your baby deserves food that nourishes them. If a large majority of your calories were coming from ultra processed grains, that would not be great for your overall health. We see the same standard should be kept for your little one, too. Because we can do better than simply filling a tiny belly.

So What Should You Feed Instead?

We wrote an article all about the first food to give a baby based on Weston A. Price nutrition principles which you can read here. A few wonderful choices for first foods included in that article are:

Sweet potato
Carrots
Squash
Avocado
Banana
Mango
Melon
Well-cooked vegetables
Puréed or finely shredded meats
Butter & Cream
Egg
Full-fat plain yogurt, if tolerated

Once your baby is developmentally ready for complementary foods, which tends to be around six months, the goal doesn't have to be finding the perfect “first food.” Think about gradually introducing foods from different food groups while continuing breast milk or formula as appropriate.
