Iron-rich foods for babies

How much iron does a baby need?

Babies aged 7 to 12 months need 11 milligrams of iron a day, according to the Recommended Dietary Allowances set by the U.S. National Academies.¹ That’s more than a toddler needs — the figure drops to 7 mg between 1 and 3 years.

In real food, 2 tablespoons of dry iron-fortified infant oat cereal carry about 4 mg — over a third of the day — before you’ve added a single other food.⁶ A spoonful of mashed lentils and some minced beef at dinner add more.

The tiny figure for the first 6 months isn’t a typo. It reflects the average iron a healthy breastfed baby takes in, because full-term babies are born with iron stores that carry them through the early months.¹

Why iron runs low around 6 months

Full-term babies usually have enough stored iron for about the first 4 to 6 months. After that, the NIH notes they’re at risk of iron deficiency at 6 to 9 months unless they get enough iron-rich solid foods or iron-fortified formula.¹

Breast milk contains iron that’s absorbed well, but not enough to meet a baby’s needs beyond 4 to 6 months.¹ USDA reference data put it at roughly 0.2 mg in 24 oz of breast milk.⁶ Standard infant formulas are fortified with 12 mg of iron per liter, which the CDC says will meet a baby’s needs through the first year.¹²

The NIH estimates that about 18% of US babies aged 6 to 12 months don’t get enough iron.¹ That matters because iron is critical for early brain development, and low iron has been linked to delays in learning and attention.³ For the older-child picture, see how much iron a toddler needs.

Iron-rich foods for babies: what a portion delivers

Baby portions are small, so these figures are for a baby-sized serving, scaled from the NIH and USDA food tables.¹⁶ Two or three across a day, alongside breast milk or formula, add up quickly.

Infant cereals vary by brand, so check the label. The USDA’s reference infant oatmeal works out to about 2 mg per dry tablespoon.⁶

Iron from meat, poultry and fish is absorbed best — but iron-fortified cereal, beans and tofu still do a lot of the work.

There are two kinds of iron. Heme iron, in meat, poultry, seafood and eggs, is absorbed more easily. Non-heme iron, in iron-fortified infant cereals, tofu, beans, lentils and dark leafy greens, is absorbed less easily, so a plant-heavy diet takes more planning.² Some plant foods, such as spinach, contain compounds that limit how much iron is absorbed.¹

Iron-rich purées and finger foods

Both work. For purées, mix fortified infant cereal with breast milk or formula, blend cooked lentils or beans until smooth, or purée well-cooked meat with a little cooking water. For baby-led weaning, try soft shredded or finely minced meat, flaked boneless fish, strips of well-cooked egg and mashed beans spread on toast strips.

Self-feeding babies can end up eating mostly fruit and vegetables, so offer an iron-rich food at every meal — our guide to purées vs baby-led weaning covers the research, and our 6-month-old food ideas turn first foods into simple meals. Whichever way you go, whole beans and chunks of meat are choking hazards: mash beans and mince or shred meat.¹¹

Pair it with vitamin C

Serving vitamin C-rich foods alongside non-heme iron helps your baby absorb more of it.² The CDC suggests oranges, broccoli, cabbage, berries, papaya, tomatoes and sweet potatoes.² Some easy pairings:

• Fortified oat cereal stirred with mashed strawberries or blueberries
• Lentils mashed with a little tomato
• Tofu with soft-cooked broccoli
• Beef with mashed sweet potato

Meat also helps the body absorb plant iron, so a little minced meat in a bean or vegetable dish gives a double boost.¹

A note on rice cereal and arsenic

Iron-fortified rice cereal is fine as part of the mix, but the CDC advises offering a variety of fortified infant cereals — such as oat, barley and multigrain — rather than only rice, because rice-only feeding can increase a baby’s exposure to arsenic.⁷

In 2020 the FDA set an action level of 100 parts per billion for inorganic arsenic in infant rice cereal, and noted that oat, barley and multigrain cereals can be a first or early cereal too.⁸ Through its Closer to Zero program, the FDA is still developing arsenic limits for other foods made for babies and young children.⁹

Do babies need iron supplements?

Some do, and that’s your pediatrician’s decision. In June 2026 the American Academy of Pediatrics updated its guidance: prevention now includes iron supplementation for exclusively breastfed babies by 6 months of age and early supplementation for babies born preterm.⁴⁵ Standard iron-fortified formula covers formula-fed babies’ needs.² The 2025–2030 Dietary Guidelines say simply that some infants require iron supplementation, and to talk with your health care professional.¹⁰

Ask your pediatrician whether your baby needs iron drops, which product, and how much. Never give an iron supplement on your own: accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6, so keep any supplements locked away.¹

The AAP now recommends screening every baby for low iron, timed by feeding — around 9 to 12 months for mostly breastfed babies and 15 to 18 months for mostly formula-fed babies.³ Cow’s milk shouldn’t be given as a drink before 12 months, because it can cause blood loss in the stool and lower iron absorption.³ For what low iron can look like, see signs of iron deficiency.
