Your baby is born with a supply of iron built up during pregnancy. By around 6 months, that supply starts to run low, right as weaning begins and you're trying to work out what on earth to put on the spoon. It's one of the nutritional topics that doesn't always come up in the standard advice. But it really is worth knowing about, because iron is such an important nutrient for your baby, and rapidly growing toddler. Iron deficiency is one of the most common nutrient deficiencies in children between 6-24 months.
We asked Lucy Upton, our resident Children's Dietitian and mum to a toddler herself, to walk us through what babies need from 9 months and how to get iron into daily meals without adding another complicated task to the list.
Why iron matters for growing toddlers
Iron plays a central role in brain development, energy production, and immune function. During pregnancy, babies build up iron reserves that carry them through the first months of milk feeding. From around 6 months, food needs to start contributing that iron instead.
The figures are worth knowing. NHS guidance on iron shares that babies aged 7 to 12 months need around 7.8mg of iron per day. After their first birthday, that figure drops slightly, but iron remains important throughout the toddler years with your toddler needing around the same amount of daily iron as a grown man. Low iron can affect concentration, sleep, growth, appetite, energy levels, and mood.
The window between 6 months and 2 years is particularly significant, because it overlaps with a period of rapid brain growth. Getting into good iron habits early matters. Most toddlers can meet their needs through food alone, which is reassuring, but it does require attention, consistency and an understanding of the right foods.
Best iron sources for 9-month-olds and beyond
Iron from food comes in two forms. Haem iron, found in meat and fish, which is absorbed far more readily by the body. Non-haem iron, found in plant foods, fortified cereals, and eggs, is absorbed less efficiently on its own. That doesn't mean plant sources aren't worth including, because they absolutely are, and there's a simple way to improve how much your little one actually absorbs (more on that below).
Good haem iron sources:
- Beef and lamb mince
- Chicken and turkey, especially the dark meat
- Oily fish, like salmon, sardines
Good non-haem iron sources:
- Iron-fortified breakfast cereals and porridge oats
- Lentils, chickpeas, red kidney beans
- Nuts and seeds (e.g. as butters, milled)
- Spinach, kale, broccoli
- Eggs and tofu
Lentils are particularly good value here. They're inexpensive, easy to cook down to a smooth or softly textured consistency for younger babies, and they deliver a solid iron hit for families eating less meat.
On portions: at 9 to 12 months, roughly 1 to 2 tablespoons of a protein source at one or two meals a day is a reasonable guide. From 1 to 3 years, this tends to increase to around 2 to 4 tablespoons, but this is simply a rough guide as every child’s intake will vary, and day to day too. Every little one is different, so the real goal is variety and regular exposure across the week rather than hitting a precise number at every sitting.
My First Pasta Bolognese is a reliable iron source: British beef mince in a vegetable and tomato sauce with wheat pasta, with a smooth texture that works well from 9 months. For fish, My First Fish Pie brings together mixed white and pink fish in a bechamel sauce with mashed potato and parsnip. It's great for babies and enjoyable well into the toddler years.
A quick note on self-feeding and finger foods: always supervise mealtimes closely when your little one is picking up food independently. Cut grapes, cherry tomatoes, and other round foods lengthways to reduce choking risk. Avoid whole nuts, popcorn, and large pieces of raw vegetable. The NHS Start for Life weaning guide covers foods to avoid and how to prepare them safely.
Boost iron absorption: The vitamin C strategy
Here's a simple tip to support your little one’s iron intake, and one that actually makes a practical difference. Pairing non-haem iron foods with a source of vitamin C helps your little one's body absorb significantly more of that iron. Vitamin C converts non-haem iron into a more absorbable form, so what else is on the plate matters alongside the iron source itself.
Some easy pairings to try:
- Iron-fortified porridge with mashed strawberries or blueberries on top
- Lentil dhal with steamed broccoli or a small squeeze of lemon juice
- Spinach pasta in tomato sauce (tomatoes bring a useful vitamin C boost)
- Beans on toast followed by soft orange or satsuma segments
My First Mild Chicken Korma brings together free range British chicken in a mild coconut curry sauce with white rice. Add a small portion of steamed peas or some soft roasted pepper alongside, and you have a colourful, well-rounded plate with both iron and vitamin C covered. On the evenings when vegetables feel like a losing battle, Cheesy Veg Bites pack hidden vegetables into easy-to-hold pieces. A little pot of tomato sauce for dipping adds extra vitamin C and tends to make them more tempting for suspicious tots.
One other thing worth knowing is that cow's milk (which should only be offered as a drink after 1 year of age) can reduce iron absorption. Offering milk at different times from iron-rich meals is a small, practical adjustment that adds up over the week, alongside being mindful of your toddlers overall milk intake.
Is my toddler getting enough? Signs and when to check
Only a blood test can truly confirm iron status, but there are some signs that can be associated with low iron in children, these include: unusual tiredness, pale skin, reduced appetite, restless legs overnight and seeming more irritable than usual. These symptoms overlap with many other things, so they're not definitive on their own. They are, however, worth raising with a professional.
The right first step is to speak to your GP or health visitor. A simple blood test can check iron levels directly. Your health visitor can also do an informal review of your little one's diet to see whether any straightforward adjustments might help. Routine iron screening isn't offered to all children in the UK, but your GP can arrange a test if there's a clinical reason, so do ask. More information is available on the NHS iron deficiency anaemia page.
Most toddlers can meet their iron needs through a varied diet that includes some meat, fish, or pulses on most days. If your little one follows a vegetarian or vegan diet, it may be worth discussing iron with a professional for more advice.
Making it work on a busy week
Weaning and feeding toddlers already has a lot of moving parts! Getting enough iron doesn't require a complicated meal plan on top of everything else. A few meals a week with mince, fish, or pulses, iron-fortified cereal at breakfast most mornings, and some fruit alongside lunch covers a good chunk of what your little one needs.
On busier evenings, having reliable frozen meals in the freezer means your tot still gets a nutritious, varied plate without everything having to come from scratch. Our Build Your Box lets you mix and match from the full range of dietitian-approved meals and snacks, made with real ingredients and suitable from 9 months. Good enough, often, is exactly enough.
