How to Cut Food for a Baby

Why shape matters more than hardness

The foods that block a small airway most effectively are the ones shaped like it: round, smooth and roughly the diameter of a windpipe. A grape and a slice of sausage are dangerous for the same reason, which is that they seal rather than lodge.

The NHS's summary of the principle is to think about the size, shape and texture of food, cut it into narrow batons, and avoid round shapes and firm foods. Everything below is that principle applied food by food.

The sizes each service publishes

The AAP asks you to cut food for infants and young children into pieces no larger than half an inch, roughly 13mm, and to teach children to chew well.

New Zealand's Ministry of Health is the only service that gives a precise measurement, in guidance written for early learning services. It asks for food to be chopped to an 8mm by 8mm size or smaller, and gives a memorable comparison: about half the width of a standard dinner fork. For children aged four to six years it also allows sticks of around 4 to 6cm long that can be picked up with one hand. Its definition of soft is equally practical: food that can be easily squashed between your thumb and forefinger.

The NHS and the HSE describe shape rather than millimetres. The HSE's finger food is a piece big enough for your baby to hold in their fist with a bit sticking out, roughly the size of your own finger, and soft, with skin, seeds, pits and bones removed.

Those are not in conflict. A finger-sized baton for holding and biting, or a piece under about 8mm for a baby using a pincer grip, are the two safe shapes.

Small round fruit

The NHS says to cut small round fruits like grapes, cherries, berries, strawberries and cherry tomatoes into quarters. HealthLink BC asks for grapes, cherry tomatoes and large berries, especially blueberries, to be cut lengthwise and into small pieces. New Zealand asks for grapes, large berries and cherry tomatoes to be quartered or finely chopped to 8mm by 8mm or smaller.

Quartered lengthways is the cut all three are describing. Halving a grape leaves a shape that is still round in cross-section; quartering it lengthways does not.

Hard pips and stones always come out first, and New Zealand asks for stones to be removed and the fruit chopped to 8mm or smaller.

Sausages, hot dogs and processed meat

The NHS's instruction is specific: cut sausages and hot dogs into short strips, cut them in half and then lengthways, or as thinly as possible, and peel the skin off, which makes them easier to swallow. It adds that it is a good idea to limit how often processed meat such as ham or sausages is given, though small amounts are fine.

HealthLink BC gives the same cut for hot dogs, lengthwise and into small pieces, and the AAP lists hot dogs, meat sticks and sausages among the foods to avoid or modify for young children.

Meat, fish and bones

The NHS asks you to remove all bones from meat or fish, cut meat into strips as thinly as possible, and remove skin and fat to make it easier to swallow. New Zealand's guidance treats cooked meat as a compressible food that can fit the shape of the airway and wedge tightly, and asks for meat to be cooked until very tender and then minced, shredded or chopped to 8mm pieces.

HealthLink BC asks for bones to be removed from chicken and fish before serving, and lists fish bones and small chicken bones among common causes of choking.

Firm raw vegetables and fruit

The NHS asks for vegetables like carrots, peppers, cucumber and celery to be cut into narrow batons, and for very young children to be given firm fruit and vegetables grated, mashed, steamed or simmered instead. Softening by steaming or simmering until soft, then cutting into slices or narrow batons, is its stated method. Larger and firmer fruit such as melon and apple go into slices rather than small chunks.

HealthLink BC asks for raw carrots and apples to be grated or finely chopped, and lists raw carrots, apples and celery among common choking foods. New Zealand offers grating raw apple or pear, slicing thinly with a peeler, or cooking until soft and cutting into strips.

Skins are worth removing. The NHS says removing the skin on fruit and vegetables makes them easier to swallow, and New Zealand notes that fruit skins are difficult to chew and can completely seal a child's airway.

Nuts, seeds and nut butters

The NHS says to chop or flake whole nuts, peanuts and seeds, and not to give whole nuts or popcorn to children under five years old. HealthLink BC's threshold is age four, and it groups whole peanuts, nuts, seeds, popcorn, marshmallows, olives with stones, dried fruit such as raisins, hard or gel sweets, chewing gum and chewable vitamins as foods not to offer until then. The AAP also works to age four or older, depending on the individual child's development and maturity.

That difference in age is real and worth knowing: five in the UK, four in Canada and the United States. Nobody permits whole nuts to a baby.

Nut butter has its own rule. The NHS says to use nut butters only as a spread or in cooking, for example in curries or swirled into porridge, and not to give peanut butter to babies and young children by itself. HealthLink BC explains why: a chunk of nut or seed butter can form a plug that blocks the airway.

Bread and dried fruit

The NHS makes a point about bread that most people have never heard: if it is not chewed properly, white bread can form a ball with a dough-like texture in the throat. Its suggestion is to lightly toast white bread or use brown bread instead, and to cut bread, chapatis, naan and other breads into narrow strips.

On dried fruit it is firm: do not give whole raisins or dried fruits to babies under the age of one, and always cut them into small pieces.

Two hazards that need a hospital rather than a cut

HealthLink BC flags that a child who has swallowed or choked on batteries, including button batteries, or on dried peas or beans, needs immediate medical attention even if they seem fine. Batteries contain chemicals that can burn, and dried peas and beans swell as they absorb water, causing a more complete blockage.

The rules around the food

Cutting is only half of it. The NHS asks you to use a high chair, with babies and young children alert and seated safely upright while eating; to supervise always; and to model chewing and swallowing properly rather than rushing. HealthLink BC adds that food should be offered in small amounts so a child does not put too much in at once, that children should be awake and alert, and that nothing should be eaten while walking, playing, or in a moving car, bus or buggy.

The HSE's version is short: never leave your baby alone while eating, and make sure they are sitting securely and supervised.

Knowing the difference from gagging

Gagging is loud and choking is quiet. That is the NHS's distinction, and it adds that a choking child's skin may begin to look blue, or, on brown and black skin, that their gums, the inside of the lips or the fingernails may look blue. Its instruction if a child cannot breathe properly is to shout for help, get them out of the high chair, support the chest and chin with one hand and give five sharp blows between the shoulder blades with the heel of the other. A paediatric first aid course is the single most useful preparation you can do.
