Starting solids, properly

Few parenting topics carry as much contradictory advice. This is the sequence as WHO and current national guidelines actually set it out: when to begin, what the first mouthful should be, what order to follow, and which old rules have been reversed.

When to start: read the signals, not just the calendar

Six months is the consistent recommendation from WHO and national dietary guidelines, but the real test is four physical signals present together. They matter more than the date — a baby who cannot yet sit steadily at six months is at genuine risk of choking if pushed.

In specific circumstances solids may start earlier, but never before 17 weeks, and only on medical advice. Starting before four months is associated with higher rates of allergy, obesity and gastrointestinal problems.

  1. 01Sits with support without toppling
  2. 02Holds their head steady unaided
  3. 03Tongue-thrust reflex is gone — a spoon is no longer pushed back out
  4. 04Watches you eat, reaches for food and opens their mouth

The first food is about iron, not cereal

The standard answer is iron-fortified infant cereal. Most people remember the cereal and forget the iron, which is the part that matters.

The iron a baby accumulates in late pregnancy runs out at around six months. Breast milk is low in iron (roughly 0.3mg/L) and cannot make up the gap. Six to twelve months is the first peak period for iron-deficiency anaemia, and the effects of iron deficiency on neurological development are not fully reversible.

So the real question behind the first mouthful is how iron gets replaced. Fortified cereal is the convenient answer. Pureed meat and liver are the more efficient ones. Home-made plain rice porridge or rice water contains no added iron and almost no nutritional density — using it as a first food wastes the window.

  1. 01Week one: iron-fortified cereal mixed with milk or warm water, thick enough to cling to the spoon but still move
  2. 02Start with 1-2 spoonfuls, in the morning, so you have the day to watch for reactions
  3. 03Build to a small half-bowl over the week, keeping milk feeds unchanged
  4. 04From week two, introduce pureed meat — a far better iron source than vegetables

Order: one food at a time, three days each

Three days on each new food before moving on is the basic allergy-watching protocol. It is not superstition: it is what lets you identify the culprit when a rash, vomiting or diarrhoea appears.

On vegetables before fruit, there is no strong evidence that a fixed order shapes later taste preferences. In practice, starting with vegetables is still a sensible choice, since sweetness needs no encouragement.

The one sequence that genuinely must be respected is texture. Puree, thick puree, minced, small lumps, finger food — this has to keep moving. Children kept on smooth puree are considerably more likely to reject lumpy food after their first birthday, and the oral muscle development that feeds into chewing and speech is affected too.

Allergenic foods now go in early

This is the guidance that has changed most in the last fifteen years. The old rule was egg after one year, peanut after three, shellfish later still. Current advice is the reverse.

The LEAP trial (2015) and the evidence that followed showed that early, regular introduction of peanut between 4 and 11 months reduced peanut allergy in high-risk infants by roughly 80%. Egg shows a similar pattern. Delaying introduction raises risk rather than lowering it.

So the approach now is to introduce the common allergens across the 6-12 month window, and then to keep them in the diet regularly — a few times a week — rather than trying once and stopping. Children with moderate-to-severe eczema or a known food allergy are high risk and should be assessed before the first exposure.

  1. 01Egg: yolk first, then the white once tolerated, always fully cooked
  2. 02Peanut: smooth butter thinned down, or ground. Never a whole nut
  3. 03Wheat: noodles or bread are enough
  4. 04Fish and shellfish: bones removed, starting with a tiny amount
  5. 05Tree nuts: only ground or as butter. Whole nuts wait until age 4-5

The short list of absolute no's before age one

This list is short, and every item has a specific reason behind it.

Honey: botulism spores can germinate in an infant gut and produce toxin. Boiling does not destroy the spores.

Salt: infant kidneys handle sodium poorly. The more practical issue is taste — the preferences set in this year persist for a long time, and a child fed salted food now will want strongly flavoured food later.

Sugar: beyond decay and empty calories, it occupies stomach capacity that is already limited.

Cow milk as a main food: the protein and mineral profile is wrong for infants, and it can cause occult intestinal blood loss leading to iron deficiency. Yoghurt and cheese are fine, because the quantities are small and they are fermented.

Juice: not recommended at all before age one. It keeps the least valuable part of fruit — sugar and acid — and discards the most valuable part, the fibre.

How much is enough: change the metric

Between 6 and 12 months, milk is still the main source of nutrition. What solids do in this period is training: swallowing, chewing, accepting new tastes and textures, and learning to feed oneself.

So counting spoonfuls is a misleading measure. Better questions: will they sit in the chair, will they open their mouth for something new, is weight still tracking their own curve, are nappies normal.

Refusing new food is the default, not a problem. The figure from the research is that a new food takes 8 to 15 exposures on average before acceptance. Concluding after two attempts that your child does not eat broccoli is a sampling error.

Two habits to avoid from day one: chasing a child around with a bowl, and feeding in front of a screen. Between them they account for most later mealtime battles.
