The short answer

The AAP recommends 400 IU of vitamin D daily for all breastfed and partially breastfed babies starting from the first few days of life. If your baby refuses the drops, try putting them on your nipple before nursing, mixing into a small amount of expressed milk, or trying a different brand as flavors vary. Most formulas contain vitamin D, so formula-fed babies may not need additional supplementation.

What Parents Should Know

According to AAP, NIH guidelines, the AAP recommends 400 IU of vitamin D daily for all breastfed and partially breastfed babies starting from the first few days of life. If your baby refuses the drops, try putting them on your nipple before nursing, mixing into a small amount of expressed milk, or trying a different brand as flavors vary. Most formulas contain vitamin D, so formula-fed babies may not need additional supplementation. At 0-3 months, start vitamin D drops within the first few days of life for breastfed babies. Place the drop on your nipple or on a pacifier. A single drop is very small and most babies tolerate it well. If baby fusses, try giving it at the start of a feeding when they are calm and hungry. It is generally considered normal when baby makes a face at the drops but still swallows them. However, you should contact your pediatrician promptly if baby shows signs of vitamin D deficiency such as soft skull bones, bowed legs, or poor growth.

By Age

What to expect by age

0-3 months

Start vitamin D drops within the first few days of life for breastfed babies. Place the drop on your nipple or on a pacifier. A single drop is very small and most babies tolerate it well. If baby fusses, try giving it at the start of a feeding when they are calm and hungry.

4-6 months

Continue daily vitamin D drops. If baby has been refusing, try a different brand as taste varies. Some brands have a neutral oil taste while others have added flavors. You can place the drop on a finger and let baby suck it off.

6-9 months

Once baby starts solids, you can mix the vitamin D drop into a small spoonful of food. Make sure baby eats the entire spoonful. Do not mix into a full bottle as baby may not finish it.

9-12 months

Continue vitamin D supplementation unless baby is drinking at least 32 ounces of formula per day. Mixing drops into a small amount of food remains an effective strategy.

12-24 months

The recommended vitamin D intake increases to 600 IU daily at 12 months. Vitamin D-fortified milk provides 100 IU per 8 ounces. If your toddler drinks 16-20 ounces of milk and eats some vitamin D-containing foods, they may still need supplementation. Discuss with your pediatrician.

Does My Baby Need a Multivitamin?

Most babies who are breastfed need vitamin D supplementation, and those who are formula-fed typically get adequate vitamins through fortified formula. A full multivitamin is generally not necessary for babies eating a varied diet. Your pediatrician can help determine if your specific baby needs any supplements based on their diet, health, and risk factors.

My Baby Refuses Iron Supplements

Iron supplements can have a strong metallic taste that many babies dislike. Mixing the supplement with a small amount of vitamin C-rich juice or fruit puree can improve the taste and enhance iron absorption. Using a syringe to place drops at the back of the cheek can help bypass the taste buds. Iron supplements may stain teeth, so brush or wipe gums after giving them.

How Can My Baby Get Enough Calcium Without Dairy?

If your baby cannot have dairy due to allergy or intolerance, there are many other calcium sources. These include calcium-fortified foods, broccoli, kale, tofu made with calcium sulfate, beans, calcium-fortified plant milks (after 12 months), and sardines. Breast milk and formula provide adequate calcium before 12 months. If dairy-free after 12 months, planning is important.

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.

When Does My Baby Need Amino Acid Formula?

Amino acid-based formulas (also called elemental formulas) are prescribed for babies with severe cow's milk protein allergy, multiple food protein intolerances, or conditions like eosinophilic esophagitis who cannot tolerate standard or extensively hydrolyzed formulas. They are the most hypoallergenic formula available because the proteins are broken down into individual amino acids, making allergic reactions virtually impossible.
