When can babies have salt?
Salt is one to actively limit, not a milestone to hit. In the first year, babies should have no added salt, because their kidneys are still developing and cannot handle much sodium.
How much is too much
The amounts are genuinely small:
- Under 12 months: less than 1g of salt a day (around 0.4g sodium).
- 1 to 3 years: up to 2g of salt a day (around 0.8g sodium).
You will not be measuring this at the table. The practical version is simpler: do not add salt to your baby's food, and go easy on the packaged and restaurant foods that are already salty.
Why babies need so little
A baby's kidneys are still maturing and are not built to clear a lot of sodium. Beyond the physical strain, early exposure nudges the palate toward salty flavors, so keeping things low now genuinely shapes later preferences.
The sneaky-salty foods
Most of a baby's salt does not come from the shaker, it comes from foods that are already salted. Keep an eye on:
- Bread and many breakfast cereals
- Cheese (choose lower-salt options and small amounts)
- Cured and deli meats: bacon, ham, sausages
- Stock cubes, gravy, and jarred sauces (soy sauce, ketchup)
- Canned foods in brine, and most takeout or restaurant meals
Flavor without salt
Food for babies does not have to be bland. Reach for herbs, mild spices, garlic, onion, and a squeeze of lemon to build flavor. A good habit for the whole family is to season your own plate rather than the pot, so you can dish up the baby's portion first. See spices and herbs for babies for ideas.

Frequently asked questions
When can babies have salt?
Babies should not have added salt in the first year. Their kidneys cannot handle much sodium, so under 12 months keep to less than 1 gram of salt a day (about 0.4 grams of sodium), which means not adding salt to food and limiting salty processed foods. Toddlers 1 to 3 can have up to 2 grams a day.
Why is salt bad for babies?
A baby’s kidneys are still developing and cannot process much sodium. Too much salt can strain them and, over time, sets up a taste preference for salty food. There is no need for added salt in a baby’s diet at all in the first year.
What foods are surprisingly high in salt?
Watch bread, cheese, cured and deli meats like bacon and ham, stock cubes and gravy, sauces such as soy and ketchup, canned foods packed in brine, and most restaurant and takeout meals. Adult ready meals and packaged snacks are often high in salt too.
Can I share my food with my baby if it has salt in it?
It is best to season your own portion at the table rather than the pot, so you can serve the baby before adding salt. When cooking for the whole family, use herbs, spices, garlic, and lemon for flavor instead of salt, then let adults add their own.
