Sodium is a naturally occurring mineral found in foods like eggs, milk (including breast milk and formula), meat, and vegetables.1 It’s an essential nutrient our bodies need in small amounts to regulate fluids in our blood and to power our neurological system but too much is not healthy.
When combined with chloride, sodium make salt, a pervasive ingredient in processed foods and staple in every kitchen. But is sodium safe for babies and toddlers? Here’s what you need to know.

When Can Babies Have Salt/Sodium?
Babies can have salt in moderation. Sodium helps regulate water balance in cells and stimulate immune function, muscle contraction, nerve function, and more.
That said, too much salt too soon is not healthy. Early and excessive exposure to sodium can prime your baby’s palate for salty foods, increase the risk of obesity, and put your child at greater risk of developing hypertension, which can lead to heart disease and stroke later in life.2
Is salt dangerous for babies?
It can be. Salt can be dangerous if consumed in excessive amounts.3 Most often, excessive salt or sodium in the diet is problematic from a long-term health perspective, though there have been cases of salt poisoning (both deliberate and unintentional) but this is extremely rare.4
The most likely risk associated with excessive salt or sodium consumption in infancy is that it may set the stage for sustained increased sodium consumption which can increase their risk of obesity and hypertension later on in life, which can ultimately lead to heart disease and stroke.5
How much sodium can a baby have each day?
It depends on your child’s age. For infants 6 months and younger, the recommended amount of sodium per day is 110 milligrams and, for babies 7 to 12 months of age, it increases to 370 milligrams.6 Keep in mind that breast milk and formula also contain sodium.
In the United States, the Food and Nutrition Board of the Institute of Medicine at the National Academy of Sciences issues nutrient recommendations called Dietary Reference Intakes or Adequate Intakes (AI). Due to insufficient data for babies, an AI for sodium has been established based on sodium levels in breast milk and the recommendations are below: Note: The milligrams of sodium listed here are not strict rules but rather guidelines.
- For infants under 6 months of age, the AI for sodium is 110 milligrams per day.7
- Babies between the ages of 7 and 12 months have an AI of 370 milligrams per day.8 9
- Children between 1 and 3 years of age have an AI of 800 milligrams per day.
Studies show that almost 80% of toddlers in the United States consume more than the maximum intake of 1,500 milligrams per day, with an average daily consumption of 2,000 milligrams in toddlers aged 1 to 3 years old.10 11
For babies and young eaters, adding salt to food is unnecessary and has not been established as safe.12 If your baby shows interest in a developmentally appropriate food that you’re eating that contains salt, before offering a portion consider how it was prepared. Is it a frozen, prepackaged, canned, or fast food/restaurant food item? If so, consider just a small portion, or better yet just skip! Is it something that was prepared at home in which a small amount of salt was used? If so, likely okay! However, it’s worth considering decreasing your own sodium intake if you regularly share food with your baby or toddler.
When can I add salt to my baby’s food?
Salt can be added to food in moderation after your baby’s first birthday. Whole, fresh foods contain less sodium than packaged and processed foods. If your baby is mostly consuming whole foods prepared at home, a pinch of salt to season a larger dish for the entire family should be fine. However, refrain from adding salt directly to your child’s food and aim to season meals with fresh herbs and spices instead. Read labels when using condiments to flavor foods as they often contain lots of sodium.
When can babies have condiments like ketchup and soy sauce?
It depends on the condiment. Ketchup may be served in moderation once your baby is 12 months old, but it would be wise to consider brands with lower salt and sugar levels. On average, commercial ketchup contains about 150 milligrams of sodium per tablespoon.
Consider avoiding fish sauce and soy sauce because they contain a substantial amount of sodium — 1,000 milligrams or more per serving. If a homemade family dish calls for soy or fish sauce, consider replacements like coconut aminos if there is no coconut allergy. While still high in sodium, coconut aminos contain roughly half the sodium compared to soy sauce per tablespoon.
Lastly, many condiments contain additives and preservatives that are inappropriate for babies and contain hidden allergens like anchovy, sesame, soy, and wheat. Read labels carefully and, when in doubt, skip the condiments. If time permits, consider homemade condiments to control amounts of salt and sugar and tailor to your family’s taste preferences.

Bottom Line on Salt for Babies & Toddlers
Sodium is an essential nutrient our bodies need but too much is not healthy.
Early and excessive exposure to sodium can prime your baby’s palate for salty foods, increase the risk of obesity, and put your child at greater risk of developing hypertension later on in life, which can ultimately lead to heart disease and stroke.13
Salt can be added to food in moderation after your baby’s first birthday, though studies show that the vast majority of toddlers are consuming too much sodium.
When shopping for foods for your baby and family, prioritize whole, fresh foods, which contain less sodium than packaged and processed foods and read labels closely when using condiments to flavor foods.
Remember: What you feed your child today lays the foundation for taste preferences for tomorrow.
