Quick Answer
Once your baby is ready for solids, usually around 6 months, offer iron-rich foods such as tender meat, poultry, beans, lentils, tofu, and iron-fortified infant cereal. Fully cooked egg and suitable fish can contribute iron too, though the amount varies by food.
Serve foods in textures your baby can manage and include an iron source regularly as their meals develop. Pair plant-based iron sources with vitamin C foods, such as soft broccoli, mashed berries, or tomato, to help the body absorb the iron. Breast milk or infant formula remains the main drink during the first year.
Why Is Iron Important for Babies?
Iron supports healthy red blood cells, which carry oxygen around the body, and plays an important role in brain development. Babies are born with iron stores, but these become less able to meet their needs as they grow. Iron-rich complementary foods are especially important from around 6 months.
Premature babies and babies born with low birth weight may have different iron needs earlier in infancy. Feeding type, growth, and medical history also affect whether a baby needs an iron supplement. Food advice should not replace a prescribed supplementation plan.
Which Animal Foods Provide Iron?
Meat contains haem iron, which is generally absorbed more readily than the non-haem iron found in plant foods. You do not need large portions to begin introducing these foods.
- Beef and lamb: Cook thoroughly until tender, then purée, finely mince, or shred finely and moisten to suit your baby's skills.
- Poultry: Offer thoroughly cooked chicken or turkey in a moist, manageable texture. Dark meat generally contains more iron than breast meat.
- Fish: Choose lower-mercury options, such as salmon, cook thoroughly, and carefully remove every bone. Fish can contribute iron, but amounts vary.
- Egg: Offer fully cooked whole egg mashed or in soft, manageable pieces. Egg contributes iron alongside other nutrients, but should not be the only iron source.
Avoid tough meat chunks, bones, and salty processed meats as routine infant foods. Fish and egg are common allergens, so introduce each separately at first and follow any allergy guidance from your baby's healthcare professional.
Which Plant Foods Provide Iron?
- Lentils: Cook until very soft and mash or purée. A thick lentil purée can be offered on a spoon.
- Beans and chickpeas: Cook thoroughly and mash or flatten them appropriately. Do not offer firm, whole, round beans or chickpeas to a baby who cannot manage them safely.
- Tofu: Choose plain tofu and serve mashed or in soft pieces suited to your baby's feeding skills. Tofu is made from soy, a common allergen.
- Iron-fortified infant cereal: Check the label for added iron and prepare according to the instructions. Offer by spoon, not in a bottle unless specifically prescribed.
Plant foods contain non-haem iron, which is absorbed less readily than haem iron. They can still be useful sources when offered regularly, with vitamin C and a varied diet.
Leafy greens can contribute iron, but a small serving of spinach is not a substitute for a consistent mix of more substantial iron sources. For vegetarian or vegan babies, ask a paediatric dietitian or healthcare professional to review iron and other nutrient needs.
How Can I Pair Iron With Vitamin C?
Vitamin C helps the body absorb iron from plant foods when eaten in the same meal. Use soft foods rather than juice.
- Mashed lentils with soft, cooked broccoli.
- Iron-fortified infant oatmeal with mashed strawberries.
- Mashed beans with cooked tomato.
- Soft tofu with puréed or finely prepared cooked bell pepper.
Adjust every ingredient to your baby's developmental stage. Remove pits and hard seeds where needed, and avoid firm raw pieces that could cause choking.
How Do I Start Without Making Meals Complicated?
Begin with small amounts when your baby shows readiness for solids, including good head control, supported upright sitting, and the ability to swallow food. As meals become established, aim to include an iron-rich option at each meal rather than saving it for an occasional serving.
You might start with a few spoonfuls of lentil purée, moist meat purée, or iron-fortified cereal. Gradually offer more variety and texture as your baby's skills develop. Let their hunger and fullness cues guide how much they eat; do not force them to finish.
If you use infant cereal, vary the grains rather than relying only on rice cereal. Plain oats are not automatically iron-fortified, so check the product label.
Does My Baby Still Need Milk Feeds?
Yes. Continue breastfeeding or offering infant formula while solids gradually increase. Iron-fortified formula contributes iron, but formula-fed babies also benefit from varied iron-rich foods when they are ready.
Do not replace breast milk or infant formula with cow's milk as the main drink before 12 months. Small amounts of cow's milk can be used in food preparation once solids begin, if appropriate for your baby, but it is not an iron-rich replacement for their usual feeds.
Does My Baby Need an Iron Supplement?
Some babies do. Breastfed babies may need supplemental iron before they are eating enough iron-rich foods, and premature or low-birth-weight babies often need an individualized plan. Babies receiving enough iron-fortified formula may not need extra iron, but your healthcare professional should assess their intake and circumstances.
Ask your baby's healthcare professional about supplementation rather than choosing a dose yourself. Iron products vary in concentration, and too much iron can be dangerous. Keep supplements locked away and follow the prescribed instructions exactly.
What Parents Can Try
- Choose one simple iron-rich option to include in each established meal.
- Keep small portions of cooked lentils, beans, or tender meat ready using safe food-storage practices.
- Pair plant sources with a vitamin C food your baby already tolerates.
- Rotate animal and plant sources if both fit your family's diet.
- Seat your baby upright and supervise throughout the meal.
- Keep offering a refused food on another day without pressure. Acceptance can take repeated opportunities.
When Should I Seek Help?
Speak with your GP or paediatrician if your baby was premature, has a very limited diet, struggles with solids, or is not growing as expected. Ask for dietitian support if you are planning a vegan diet or excluding several food groups.
Paleness, unusual tiredness, poor appetite, or reduced activity can have many causes, including iron deficiency. These symptoms need assessment rather than a diagnosis based on diet alone. Your healthcare professional can decide whether blood tests or treatment are appropriate.
If your baby may have swallowed too much iron supplement, contact your local poison service or emergency services immediately. Do not wait for symptoms.
Key Takeaway
Offer iron-rich foods regularly from the start of complementary feeding, using safe textures and a variety of sources. Meat, lentils, beans, tofu, and iron-fortified infant cereal are practical choices. Add vitamin C to plant-based meals, continue appropriate milk feeds, and ask your baby's healthcare professional whether supplements are needed.
