Two tins of baby cereal can sit on the same shelf, from the same brand, with only one of them carrying a warning line underneath the nutrition panel. The line tracks a single number printed a few centimetres above it — the age statement on the front.
Take two products from Bellamy’s Organic. Organic Baby Rice with GOS, 125 g, is marked 4+ Months on the front. Below the nutrition panel, the page states: Not recommended for infants under the age of 4 months. Apple & Cinnamon Baby Porridge, marked 6+ Months, carries no such line anywhere on the page. Same brand, same category. One carries the warning and one doesn’t.
What the age statement is legally required to say
Look at the front of the pack first. The Code that governs this category is Standard 2.9.2, Food for infants, and it requires every pack to carry a statement indicating the minimum age, expressed in numbers, of the infants for whom the food is recommended (2.9.2, clause 7(3)(b)). That number is not decoration. The Code also sets a floor it enforces directly: a label must not include a recommendation, stated or implied, that the food is suitable for infants under the age of 4 months (2.9.2, clause 7(2)). Four months is as low as an Australian baby food label can go, so a lower number is not something you will find in the aisle.
Why does a 4-month claim carry a warning about 4 months?
Where a food is recommended for infants under 6 months, which covers any pack claiming 4 or 5 months the way the rice does, the Code requires the pack to carry, tied to that same age statement, the exact warning: Not recommended for infants under the age of 4 months (2.9.2, clause 7(3)(c)). A pack claiming 6 months or older never trips this clause at all, because the clause only reaches food recommended for infants under 6 months. So the rice carries the line because it claims 4 months. The porridge carries nothing because it claims 6.
The same number sets the compositional rules too
The age claim doesn’t only decide the warning. It decides which compositional rulebook the recipe has to satisfy. A cereal-based food that’s more than 70% cereal on a moisture-free basis, and promoted from 6 months, has to carry at least 20 mg of iron per 100 g on that same moisture-free basis (2.9.2, clause 4) — a fiftieth of a gram in a full 100 g, which is not a quantity anyone can see in a tin. A food promoted from 4 months instead sits under a different clause (2.9.2, clause 5), which allows added iron and vitamin C but sets no iron floor at all. Claim 6 months and the recipe has to clear a bar. Claim 4 and there’s no bar to clear. Which inverts what the warning line seems to say: the pack carrying the caution is the one with no iron floor beneath it, and the pack that says nothing is the one held to the higher compositional bar. What the front of the pack tells you stops there, though. Both Bellamy’s ingredient panels list Mineral (iron) and neither gives a quantity, so whether either one clears the 20 mg floor is not clear from the ingredient list alone. Peeka hasn’t worked either panel through moisture-free here.
A separate clause catches protein: push past 3 g of protein for every 100 kJ, which is about 24 kilocalories, and the pack needs a different warning again, Not suitable for infants under the age of 6 months (2.9.2, clause 8(1)(b)). Sugar has its own trigger too. The word sweetened becomes mandatory once added sugars, honey or native bee honey push past 4 g per 100 g, which is about a teaspoon of sugar by weight in every 100 g (2.9.2, clause 7(3)(d)). Neither Bellamy’s pack uses the word, and neither ingredient list names an added sugar or honey. And the age number reaches the texture as well: a food meant for infants under 6 months has to be formulated and manufactured to a consistency that minimises the risk of choking (2.9.2, clause 3(4)) — the second place in the standard where claiming a lower age adds an obligation rather than removing one.
What the standard never touches
Standard 2.9.2 only covers food the Code defines as food for infants, and Standard 1.1.2 fixes an infant as a person under the age of 12 months (1.1.2). Infant formula, formulated meal replacements and formulated supplementary foods sit outside 2.9.2 entirely, and so does unprocessed fruit and veg (2.9.2, clause 2). A punnet of blueberries on the next shelf carries no age statement and no warning line. The standard was never written to reach it. Nothing in this category, whatever age it claims, can be marketed as an infant’s sole source of nutrition either (2.9.2, clause 9(1)).
So when do you start solids?
None of that tells you when to start, only when a pack is legally allowed to say it belongs in your baby’s rotation at all. That answer sits with ASCIA, the Australasian Society of Clinical Immunology and Allergy, and it isn’t printed on any tin. ASCIA’s guidance is that solid food should start when a baby shows signs of readiness, usually around 6 months of age and not before 4 months. It also says the common allergy-causing foods should be introduced within the first year, starting soon after solids begin, not delayed. The 4-month figure on a cereal pack and the 4-month figure in ASCIA’s guidance land on the same number for a different reason. One is the legal floor beneath every age claim in the category. The other sits closer to the earliest edge of a readiness window, read against your own baby.
The warning-trigger mechanism is the firmer half: claim under 6 months and the pack must print the line, with no discretion built into it. Either the age statement trips clause 7(3)(c) or it doesn’t, and you can check that against any pack in the aisle. ASCIA’s readiness window is softer ground — expert guidance, updated in 2026 and written as a range rather than a rule with a printing requirement attached, and reading it against your own baby is the whole point of a window instead of a date.

You can run the same check yourself next time you’re standing in front of the shelf. Find the front-of-pack age first. If it reads 4 or 5 months, the warning has to be printed with it by law. If it reads 6 months or older, the pack was never required to carry the line, whatever else is in the tin. Both Bellamy’s products sit under the same version of that rule: Compilation No. 4 of Standard 2.9.2, in force since 13 September 2024.
