Can Babies Eat Salt?
Do not add salt before 12 months. Babies need a tiny amount of sodium and they already get it from milk and everyday food. Their kidneys cannot clear the excess yet. You do not need to hunt down every trace of salt, you just need to stop adding it and keep an eye on a handful of salty foods.
Salt is the one seasoning nearly everyone reaches for without thinking, which is exactly why it needs a mention when a baby starts solids. The issue is not that salt is poison. It is that a baby's daily allowance is genuinely tiny, milk and ordinary food already cover it, and their kidneys have no spare capacity to deal with the rest.
What is salt?
Table salt is sodium chloride. The sodium is the part that matters for health, and it makes up about 40 percent of salt by weight, which is why labels quote the two differently. Sea salt, rock salt, pink salt and flaky salt are all essentially the same thing for this purpose. None of them is a gentler option for a baby.
Once you stop adding salt you notice how much flavour food has on its own. Roasted carrots go sweet, and a spoon of yogurt stirred into a mash adds a tang that does the same job salt was doing.
How much salt is too much?
These are the upper limits by age, not amounts to aim for. Under one, the target is effectively zero added:
| Age | Maximum salt per day | As sodium |
|---|---|---|
| Up to 12 months | Less than 1 g | Less than 0.4 g |
| 1 to 3 years | 2 g | 0.8 g |
| 4 to 6 years | 3 g | 1.2 g |
| 7 to 10 years | 5 g | 2 g |
| 11 years and up | 6 g | 2.4 g |

When can babies have salt?
Salt is not a food you introduce on a date. It is one you keep low and let creep up slowly as they grow:
Cook without salt, or take out your baby's portion before you season the pan. Skip stock cubes, gravy and soy sauce entirely unless they are the low salt kind made for babies.
The limit doubles to about 2 g a day, which sounds generous until you count the bread and cheese. Keep cooking unsalted and let them eat the family meal.
Limits rise with age, but the habits set now tend to stick. A child raised on lightly salted food usually finds heavily salted food unpleasant, which is a useful thing to hand them.
Never use salt as a remedy: giving a child salt water to make them vomit is dangerous and can cause salt poisoning. If your baby has swallowed something they should not have, call poison control or emergency services and follow their instructions instead.
The salty foods that catch parents out
Most people know crisps are salty. These are the ones that slip past:
Go easy on these
Flavour without salt
- Garlic, onion and leek softened slowly until sweet
- Herbs like basil, oregano, thyme and dill
- Mild spices such as cumin, paprika and cinnamon
- A squeeze of lemon or a spoon of plain yogurt
- Roasting rather than boiling, which concentrates sweetness
- Low salt or no added salt stock, or just cooking water
Risks and safety
If your baby has eaten one salty meal at a family lunch, do not panic. Offer water, move on, and go back to normal at the next meal. The concern with salt is cumulative rather than sudden: kidneys working harder than they should over months, blood pressure nudged upward over years, and a palate that learns to expect salt in everything.
Very large amounts are a different matter. Salt poisoning is rare but serious, and it usually involves a child getting into a salt container or being given salt water deliberately. Signs include intense thirst, vomiting, irritability, confusion and drowsiness. That needs urgent medical attention. The World Health Organization recommends cutting salt across the whole population, and the first year is the easiest time to start.
Read the label: foods sold for babies and toddlers are not automatically low in salt. Check the sodium figure per 100 g rather than trusting the packaging. Anything over 0.6 g of sodium per 100 g counts as high.
Salt FAQ
Can babies eat salt?
Do not add salt to a baby's food before 12 months. Their kidneys are too immature to clear it. Babies under a year need less than 1 g of salt a day, which they already get from breast milk, formula and ordinary food, so anything you add is on top of a limit they have nearly reached.
How much salt can a baby have?
Under 12 months, less than 1 g of salt a day, which is about 0.4 g of sodium. From 1 to 3 years the limit is about 2 g of salt a day. These are upper limits rather than targets, and there is no need to add any salt at all in the first year.
What happens if a baby eats too much salt?
One salty meal is unlikely to do harm, though it may make your baby thirsty and unsettled. The real concern is a regular high salt diet, which strains developing kidneys, raises blood pressure over time and trains a child to prefer salty food. Very large amounts can cause serious salt poisoning.
Which foods are surprisingly salty for babies?
Bread, cheese, ham and bacon, sausages, stock cubes and gravy, jarred sauces, olives, soy sauce, yeast extract spreads and most crisps and savoury snacks. Bread is the sneaky one, because a slice is mild tasting but adds up quickly across a day.
