Can babies have cheese?

The verdict

Yes, from around 6 months, provided it is pasteurised, full-fat and not one of the excluded types.

The NHS states it directly: cheese can form part of a healthy, balanced diet for babies and young children and provides calcium, protein and vitamins, and babies can eat pasteurised full-fat cheese from 6 months old, including hard cheeses such as mild cheddar, cottage cheese and cream cheese. Ireland's HSE uses almost identical wording, naming cheddar, cottage cheese and cream cheese from 6 months.

The cheeses to leave out

The NHS says babies and young children should not eat mould-ripened soft cheeses such as brie or camembert, ripened goats' milk cheese, or soft blue-veined cheese such as roquefort, because there is a higher risk that these cheeses carry listeria. It adds that many cheeses are made from unpasteurised milk and it is better to avoid these for the same reason, and that labels can be checked.

The HSE lists the same exclusions: brie, camembert, ripened goats' milk cheese such as chevre, soft blue-veined cheese such as roquefort, and any cheese made from unpasteurised milk.

The reason these particular cheeses are singled out is chemistry rather than reputation. Listeria monocytogenes is unusual among food pathogens in that it multiplies at refrigerator temperatures, and it does best in moist, low-acid, high-salt conditions. Mould-ripened and soft blue cheeses become less acidic as they ripen, which is exactly the condition listeria likes. Hard cheeses are drier and more acidic and do not support it in the same way.

Cooking changes the answer

Both the NHS and the HSE make the same exception: these cheeses can be used as part of a cooked recipe, because listeria is killed by cooking. The NHS gives baked brie as the example of a safer option. Cheese melted through a pasta sauce or baked into a dish is a different proposition from cheese eaten cold off a board.

How to serve cheese safely

Cheese is a genuine choking hazard in the wrong shape, and this is not a minor point. The AAP's choking prevention list includes chunks of cheese and string cheese among the foods to avoid or modify for young children, and its general rule is to keep high-risk foods from children until 4 years of age or older, while noting that round, firm foods can be served if completely chopped into tiny pieces.

The NHS gives the practical instruction for cheese in one line: either grate cheese or cut it into short, narrow strips. HealthLink BC lists grated hard cheese among safe finger foods, and the Canadian Paediatric Society names full-fat grated or cubed pasteurized cheeses among milk products for babies after 6 months.

What that rules out is a cube of cheddar the size of a die, a chunk pulled off a block, and a stick of string cheese eaten whole. All three are firm, compressible and close to airway width, which is the combination that causes complete blockage rather than a cough. Grated cheese carries none of that risk, melts readily into other food, and is easy for a baby to pick up in a pincer grip.

Salt, which is the quiet problem

Cheese is one of the saltier things in a baby's diet, and the limits at this age are strict. The NHS states that children under 1 year old should have less than 1g of salt a day, rising to no more than 2g a day for ages 1 to 3, because babies' kidneys are not fully developed and cannot process it.

That figure is easier to reach than people expect. Hard cheeses, halloumi, feta and processed cheese slices are all significant salt sources, and processed cheese is usually the saltiest of the group. Mild cheddar is the type both the NHS and HSE name for a reason.

The practical approach is to treat cheese as a flavour and a calcium source rather than a filler: a sprinkle of grated cheese over vegetables, or a small amount melted into a sauce, rather than cheese as the main component of two meals a day. If cheese is in a meal, that is usually the meal not to add any other salty ingredient to.

Full-fat, not reduced-fat

The NHS recommends full-fat cheeses and dairy products up to the age of 2, because young children need fat and energy to grow, and says lower-fat dairy can be introduced gradually once a child is 2 and eating and growing well. Australia's Raising Children Network sets the same boundary, advising against reduced-fat dairy until 2 years.

Reduced-fat cheddar and light cream cheese are not unsafe. They are simply the wrong product for a child under 2, whose energy needs relative to their stomach size are higher than an adult's.

Cheese as an allergen

Cheese is a cows' milk product, so it introduces cows' milk protein, one of the common allergens. Current guidance is not to delay it. HealthLink BC's instruction is to introduce common food allergens, including milk products, when a baby starts solid foods at about 6 months, and to keep offering them regularly once tolerated, because that may help prevent a food allergy developing.

As with any allergen, introduce it on its own rather than alongside two other new foods, so a reaction can be traced. If your baby has a diagnosed cows' milk protein allergy, cheese is not a workaround: it contains the same proteins. The NHS advises against cutting out a major food group without talking to a health visitor or GP, who may refer you to a registered dietitian.

Where guidance differs

The UK and Ireland word this almost identically, down to naming cheddar, cottage cheese and cream cheese from 6 months and excluding brie, camembert, chevre, roquefort and unpasteurised cheese.

North America emphasises the choking shape more than the listeria list. The AAP explicitly names chunks of cheese and string cheese as choking hazards; Canadian guidance defaults to grated or cubed pasteurized cheese. Australian guidance from ASCIA simply lists cheese among the dairy foods to include in the first year.

Follow both halves and you satisfy everyone: pasteurised, full-fat, not mould-ripened or blue, and grated or in narrow strips rather than chunks.
