Is My Baby Getting Too Much Salt?
The short answer
Babies under 12 months should have less than 1 gram of salt (400mg sodium) per day, and toddlers 1-3 years should have no more than 2 grams of salt (800mg sodium) per day. Their immature kidneys cannot process excess sodium efficiently. While you should not add salt to baby food, do not stress if your baby occasionally eats a higher-sodium food.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Breast milk and formula naturally contain the right amount of sodium for babies. No additional salt or solid foods are needed.
When starting solids, do not add salt to any baby foods. Baby's taste buds do not need added salt, and their kidneys are still maturing. Plain fruits, vegetables, and grains are ideal first foods.
As your baby eats more table foods, be mindful of sodium in processed foods like canned vegetables, bread, and cheese. Choose low-sodium options when possible. Small amounts of naturally occurring sodium in foods are fine.
As baby joins family meals, you may need to set aside a portion before adding salt for the rest of the family. Read labels on packaged foods. Choose unsalted or low-sodium versions of crackers, cereals, and canned goods when possible.
Toddlers can handle slightly more sodium than babies, but processed foods can still contribute too much. Continue choosing low-sodium options when possible. It is fine for toddlers to eat family meals with moderate salt. Focus on a balanced diet overall rather than stressing about every milligram of sodium.
What Should You Do?
When to take action
- Baby occasionally eats a food that has some sodium such as cheese or bread
- You do not add salt to baby's food but baby eats family meals with mild seasoning
- Baby drinks plenty of breast milk, formula, or water alongside solid foods
- Baby regularly eats very salty processed foods like chips, deli meats, or canned soups
- Baby seems excessively thirsty all the time
- You are unsure how to prepare family meals that are appropriate for baby's sodium needs
- Baby has consumed a very large amount of salt and is showing symptoms like extreme thirst, vomiting, or lethargy
- Baby seems dehydrated despite adequate fluid intake

Related Feeding Concerns
Toddler Eating Too Much Salt or Sodium
Babies and toddlers need very little sodium in their diet, and their kidneys are less efficient at processing excess salt. Babies under 1 year should have less than 400mg of sodium per day (about 1g of salt), and toddlers ages 1-3 should have less than 800mg per day. Most salt in children's diets comes from processed foods, restaurant meals, bread, cheese, and deli meats - not from the salt shaker. You do not need to add salt to homemade baby food. While occasional salty snacks are not harmful, consistently high sodium intake can affect developing kidneys and establish unhealthy taste preferences.
What Are the Best First Foods for My Baby?
The best first foods for babies are iron-rich foods like iron-fortified infant cereal, pureed meats, and beans. There is no required order for introducing foods, but iron-rich options are prioritized because babies' iron stores from birth begin to deplete around 6 months. Single-ingredient fruits, vegetables, and grains are all appropriate early foods.
Heavy Metals in Baby Food
Trace amounts of heavy metals (arsenic, lead, cadmium, and mercury) have been found in many commercial baby foods, including rice-based products, fruit juices, root vegetables, and teething biscuits. These metals occur naturally in soil and water and can accumulate in food crops. While the levels found are generally low, chronic exposure during early development is a concern. You can reduce your baby's exposure by offering a varied diet, limiting rice-based products, and choosing a diversity of grains and produce.
When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
Could My Baby Be Aspirating During Feeding?
Aspiration occurs when food or liquid enters the airway instead of the esophagus. Signs include coughing or choking during every feed, a wet or gurgly voice after eating, recurrent chest infections, and breathing changes during meals. Silent aspiration can occur without obvious coughing. If you suspect aspiration, contact your pediatrician as a swallowing study can diagnose it.
