One of the most common questions parents ask me is:

“We are starting solids soon...what is the best first food?”

Here’s the great news: you can start with almost ANY real food.

There is no evidence that starting with fruit makes babies “prefer sweet foods.” Breastmilk and formula are naturally sweet, so your baby is already familiar with that taste.

But if there’s one thing I encourage parents to prioritize when starting solids, it’s this:

Iron-rich foods.

Around 6 months of age, your baby’s natural iron stores begin to drop, and iron becomes one of the most important nutrients to focus on for brain development, growth, and healthy blood.

In this guide, I’ll walk you through:

• Why iron matters so much

• The best high-iron foods for babies

• Easy iron-rich puree ideas

• How to improve iron absorption

• Whether cereal or supplements are necessary

Why iron is so important for babies & toddlers

So, what exactly is iron, and why are high-iron foods important for your baby?

Iron is a mineral that plays a crucial role in maintaining healthy blood.

It is essential for making hemoglobin, a protein found in red blood cells that transports oxygen from the lungs throughout the body. This is pretty necessary stuff, right?

But why is it so important for babies?

Well, apart from carrying oxygen from the lungs to other parts of the body, iron is also vital for proper brain or neurological development in infants and children.

As babies experience rapid growth, their bodies will demand more iron to support their development.

Babies acquire iron through three main sources:

• Circulating Iron Stores from Mom: Babies inherit some iron stores from their mothers that typically last for about four months.

• Breast Milk: While breastfed babies receive a small amount of iron from breast milk, it's often not sufficient to meet their growing needs.

• Formula: Formula-fed babies get iron from the formula they consume, but incorporating iron-rich foods into your baby's diet becomes important as they start solids.

• Iron fortified foods: Many foods marketed toward babies contain added iron, especially baby cereals. 

It's worth noting that babies, especially those who are exclusively breastfed, are more likely to develop anemia, a condition where the body doesn't have enough healthy red blood cells. 

How much iron do babies & toddlers need?

According to pediatric guidelines:

• Babies 0-6 months: 0.27 mg per day (met through stores + milk)

• Babies 7-12 months: 11 mg per day

• Toddlers 1-3 years: 7 mg per day

That 7-12 month window is when iron needs jump significantly, which is why iron-rich solid foods become so important around 6 months of age.

This does not mean every bite needs to be high in iron. But offering at least one iron-rich food per day is a smart strategy.

Signs of low iron in babies

Iron deficiency can lead to anemia. Symptoms may include:

• Pale skin

• Increased fussiness

• Fatigue or sleepiness

• Poor feeding

• Slower growth

Most pediatric providers screen at 9 or 12 months using either a finger poke or taking blood from your baby's vein. It is usually not obvious when a baby is anemic.

But prevention is easier than treatment. 

Types of iron in baby foods

There are two types:

Heme Iron (Best Absorbed)

Found in animal products:

• Beef

• Lamb

• Dark meat turkey

• Chicken thighs

• Sardines

• Egg yolks

Non-Heme Iron (Plant-Based)

Found in:

• Lentils

• Beans

• Tofu

• Spinach

• Quinoa

• Fortified cereals

Non-heme iron is absorbed less efficiently.

So here’s the trick:

Pair with Vitamin C

Vitamin C dramatically increases iron absorption.

Great vitamin C pairings:

• Strawberries

• Oranges

• Mango

• Sweet potato

• Bell peppers

• Broccoli

• Tomatoes

When creating high iron baby puree recipes, combining iron + vitamin C is ideal.

Is bone marrow a good source of iron for babies and toddlers & is it safe?

Bone marrow has become more popular in the last few years, especially among families interested in nutrient-dense, whole foods.

I see so many videos of babies eating bone marrow and they get a lot of comments and engagement!

So, Can babies eat bone marrow?

The short answer:
Yes, when prepared safely and offered in an age-appropriate way.

Why do parents consider bone marrow?

Bone marrow contains:

• High in fat (which is good for brain development)

• Fat-soluble vitamins

• Some iron

• Collagen and other nutrients

It is soft, spreadable, and easy to mash, which makes it texture-friendly for babies learning to eat.

However, it is important to understand something clearly:

There are better sources of iron out there.

While it contains some iron, it does not provide nearly as much as red meat, lentils, or fortified cereals. If your goal is preventing iron deficiency, bone marrow should not replace iron-rich muscle meats like beef or lamb.

Think of bone marrow as a nutrient-dense fat source, not as the best option for iron.

What store bought food is high in iron for babies and toddlers?

The best piece of advice I can give is to learn to read the nutritional label to see if it is an iron-rich food for your baby.

Look for baby food with ANY iron content, but be cautious not to rely solely on marketing claims of being "high in iron." It may not be as high as you'd imagine.

Is iron-fortified cereal a good first food for babies?

You only have to serve baby cereal if you want to. There are some benefits and some drawbacks to consider.

Benefits:

• It is bland and usually well-accepted when it is mixed with either breast milk or formula.

• You can adjust the texture to make it thicker or thinner based on your baby's development.

• It is an easy way to get added nutrients like iron. You can easily add food with vitamin C like freshly squeezed orange juice so the body can absorb the iron even better.

Drawbacks:

• It is often made with rice, which can be constipating and has a higher level of heavy metals.

• For ways to avoid heavy metals in baby food, read more here 

• It does not encourage flavor variety when it is fed to babies daily.

• Grandparents often tell you to put it in your baby's bottle to help them sleep better - this is not true.

If you want to introduce baby cereal, choose one that is oatmeal or quinoa-based.

We use Earth's Best oatmeal cereal once every few days, which has protein and fiber!

Does my baby need an iron supplement?

Your pediatric provider will monitor your child’s iron levels at either the 9 or 12-month check-up. It may be necessary to supplement if your provider recommends it. 

Let’s be honest though - iron is NOT the tastiest and it can be really hard to get your baby to take it. Your pediatrician may also suggest pairing it with some orange juice to help the iron absorb better.

In my experience, babies may refuse iron supplements, but I see babies do well with novaferrum.

How do I know if my baby is getting enough iron?

It is recommended that all babies get bloodwork to check for anemia at either the 9 or 12-month well check. Some clinics check a hemoglobin level, while others do a complete blood count (CBC). This may be done through a finger-stick or through getting blood from a vein (also known as a venipuncture).

Reach out to your pediatric provider to see how they check.

Common mistakes parents make when focusing on iron

1. Waiting too long to introduce iron-rich foods
   After 6 months, babies’ iron stores begin to drop. Iron should be introduced early and offered regularly. It is up to you to decide what iron-rich foods you should offer, but it is important like offering allergens!

2. Relying only on fruit and vegetables
   While nutritious, most fruits and vegetables are not high in iron. It can be scary to offer meats, but they are a great source of iron for babies and toddlers. Meats can be ground into purees or you can offer them as finger foods.

3. Serving plant-based iron without vitamin C
   Your baby would need to eat a lot of spinach to Pairing matters for absorption. 

4. Offering excessive dairy in toddlers
   Too much milk (over 16–20 oz per day after 1 year) can interfere with iron absorption and increase anemia risk. If your baby loves dairy (milk, cheese, yogurt) you may consider asking your pediatric provider to test for iron deficiency anemia.

5. Assuming cereal is required
   Iron-fortified cereal is helpful, but not mandatory. It packs a punch and has a bland taste. It is easy to mix with breastmilk or formula if desired. Mix it with vitamin C-rich foods to help absorption!

Iron doesn’t need to feel stressful, but it does need to be prioritized.

Frequently Asked Questions about iron-rich foods for babies & toddlers

What are the best iron-rich foods for a 6 month old?

The best iron-rich foods for babies starting solids include:

• Ground beef

• Dark meat chicken or turkey

• Lentils

• Beans

• Tofu

• Sardines

• Egg yolks

• Iron-fortified oatmeal

Animal-based (heme) iron is absorbed best, but plant sources work well when paired with vitamin C.

Can I start solids with meat?

Yes. Meat is an excellent first food for babies.

It is:

• High in iron

• High in zinc

• Easy to puree or shred

• Developmentally appropriate at 6 months

There is no rule that says babies must start with cereal or vegetables.

Is baby cereal necessary for iron?

No.

Iron-fortified cereal can be helpful, but it is not required if your baby is regularly eating iron-rich foods like meat, beans, lentils, tofu, or fortified oatmeal.

Many families choose to use oatmeal-based cereal occasionally rather than daily.

What blocks iron absorption in babies?

A few things can reduce iron absorption:

• Calcium (large amounts at the same meal)

• Excess dairy in toddlers

• Not pairing iron with vitamin C

This doesn’t mean you need to micromanage every meal, just aim to include vitamin C regularly when serving plant-based iron foods.

What are early signs of iron deficiency in babies?

Early iron deficiency can be subtle. Signs may include:

• Pale skin

• Fatigue

• Irritability

• Poor feeding

• Slower growth

Most pediatricians screen between 9-12 months.

Can babies get too much iron?

It is rare for babies to get excess iron from food alone.

Iron supplementation should only be given if recommended by your pediatric provider.

There are numerous sources of iron to choose from when introducing solid foods to your baby.

Offering a wide variety of foods will help ensure they get the iron they need for healthy development. It does take some effort, but iron for babies is a crucial component for their well-being.

If you ever have concerns about your child's iron levels, don't hesitate to reach out to your pediatric provider for guidance and support.
