Somewhere between the baby-cereal aisle and the tenth article about iron, "doing solids right" can start to feel like an exam. It isn't. You don't need a perfect plan — mostly a little iron, most days, alongside the milk your baby already loves.

Why iron matters from around 6 months

Babies are born with a store of iron that, together with the iron in breastmilk and formula, carries them through roughly the first 6 months. After that, those stores naturally start to run down — and a growing baby's body, especially their fast-developing brain, needs more iron than milk alone now provides.

That's a big part of why solids start around the middle of the first year. The WHO, the AAP and Australia's Raising Children Network all point to around 6 months as the window to begin, once your baby shows they're ready: good head control, sitting with support, and showing interest in food.

Iron isn't about cramming in huge amounts. It's about offering iron-containing foods every day as part of normal meals.

Iron-rich first foods

You have lots of options, and both purees and soft finger foods count. Good sources of iron include:

  • Iron-fortified baby cereal — often suggested as an easy daily starting point
  • Meat and poultry — beef, lamb, chicken, well cooked and soft or pureed
  • Fish — soft, boneless, well cooked
  • Eggs — cooked through
  • Legumes — lentils, chickpeas, beans, well cooked and mashed
  • Tofu — soft and well mashed or in finger-sized pieces
Food type Easy ways to serve Texture tip
Iron-fortified cereal Mixed with breastmilk or formula Start runny, thicken over time
Meat / chicken Pureed, finely minced, soft strips Moist, never stringy
Legumes Mashed lentils, smooth hummus Soft enough to squash on the gum
Egg Scrambled soft, mashed hard-boiled Cooked all the way through

Pair iron with vitamin C

A simple trick that genuinely helps: serve iron-rich foods alongside vitamin C foods, which help the body absorb the iron — particularly the iron from plant foods like legumes and fortified cereal.

Vitamin C foods that suit babies include soft cooked or mashed broccoli, capsicum, tomato, kiwi, strawberry and citrus (offered safely as soft pieces or puree). So lentils with a little mashed tomato, or fortified cereal with mashed kiwi, are quietly doing more than they look.

A gentle guide — follow your baby's appetite, not the clock
StageAmount
~6 monthsOnce a day, building up1-2 tsp
7-9 monthsAround 2-3 meals a day2-3 tbsp
9-12 months3 meals plus snacksApprox 1/4-1/2 cup

These amounts are a starting picture, not a target to hit. Some days they'll eat heartily; some days barely a taste. Both are normal.

Milk keeps going

Starting solids does not mean winding milk down. Across the entire first year, breastmilk or formula stays your baby's main source of nutrition — solids are added around it, not instead of it. Offer milk feeds as usual and let food be the extra, exploratory part of the day.

A few safety notes worth keeping

A note on vitamin D and supplements: guidance varies by region and by whether your baby is breastfed, formula-fed, and how much sun exposure they get. The AAP recommends a daily vitamin D supplement for breastfed babies, while Australian advice depends on individual risk factors. Iron supplements are sometimes recommended too — but only on advice. Don't start any supplement on your own.

If you're worried about iron, a fussy eater, growth, or your baby seems pale or unusually tired, that's a conversation for your GP or child-health nurse — they can check in properly.

You're doing the right thing just by thinking about this. Offer iron most days, keep the milk flowing, and let the rest unfold gently.
