Someone at the hospital mentioned vitamin D drops, or maybe nobody did and you just read about them at 3 a.m. Now you’re wondering if your baby needs them, how much to give, and whether you’ve missed something. Here’s a clear answer on vitamin D drops for baby, based on AAP, CDC and NHS guidance, with a simple table by feeding type and a quick label check.
Quick answer: does my baby need vitamin D drops?
- Breastfed or partly breastfed babies: the AAP and CDC advise 400 IU of vitamin D every day, starting in the first few days of life.
- Formula-fed babies: the CDC says a supplement isn’t needed if your baby drinks 32 ounces or more of infant formula a day, because formula is fortified with vitamin D.
- Why: the CDC says vitamin D helps children build strong bones, and breast milk usually doesn’t provide all the vitamin D a baby needs.
- From 12 months: the AAP and CDC say toddlers need 600 IU a day. Ask your pediatrician whether your child still needs drops or gets enough from food and milk.
- Check the label: products differ in how much vitamin D is in one drop or one dropper. Give only the dose on your product’s label, using the dropper that comes with it.
- In the UK: the NHS advises a daily supplement of 8.5 to 10 micrograms for breastfed babies from birth to 1 year.
Who needs vitamin D drops? A table by feeding type
| How your baby is fed | What US guidance says | Source |
|---|---|---|
| Breast milk only | 400 IU vitamin D every day, starting in the first few days of life | AAP, CDC |
| Breast milk and formula | 400 IU every day, unless your baby drinks 32 ounces or more of formula a day | AAP, CDC |
| Formula only, 32 oz or more a day | No supplement needed: formula is fortified with vitamin D | CDC |
| Formula only, less than 32 oz a day | The AAP advises a supplement for babies who drink less than 32 ounces of fortified formula a day. Ask your pediatrician how much. | AAP |
| 12 months and older | 600 IU a day from all sources. Ask your pediatrician about drops versus food and milk. | AAP, CDC |

Why breastfed babies need extra vitamin D
Needing drops doesn’t mean anything is wrong with your milk. The CDC simply notes that breast milk usually doesn’t provide all the vitamin D a baby needs. The NHS says its advice applies whether or not you take a vitamin D supplement yourself.
What about sunlight? The AAP advises keeping babies younger than 6 months out of direct sunlight, so sunshine isn’t a practical way to get vitamin D for young babies. Our guide to sunscreen for babies explains sun safety by age.
The 3-step label check before the first dose
Vitamin D drops for babies are not all the same strength. The AAP notes that some liquid products give 400 IU in a single drop. Others measure the dose with a dropper. Before you start:
- 1. Find the amount per dose. Look for “400 IU” (10 micrograms) and check whether that’s per drop or per dropper.
- 2. Use the dropper that came with the product. Don’t swap droppers between brands, because they may not measure the same amount.
- 3. Give it once a day, as the label says. Follow the instructions on your product for how to give it. If anything on the label is unclear, ask your pediatrician or pharmacist.
Tip: give the drops at the same time every day, for example at the first feed of the morning, so it becomes part of your routine. A simple log, like our Feeding & Diaper Log, can help you remember.
How long do babies need vitamin D drops?
The AAP and CDC give amounts by age rather than a fixed stop date. Babies under 12 months need 400 IU a day, and toddlers need 600 IU a day. After 12 months, the CDC notes that plain whole cow’s milk is a good source of vitamin D. Whether your child still needs drops depends on what they eat and drink, so ask your pediatrician at the 12-month check-up.
In the UK, the NHS recommends a daily supplement of 10 micrograms of vitamin D for children aged 1 to 4.
If you missed days or only just found out
Many parents only hear about vitamin D drops weeks after birth. If that’s you, you’re not alone. Talk to your pediatrician about starting or restarting the drops. Don’t give extra to make up for missed days.
When to talk to your doctor
- Before you start drops, if your baby was born early, has a health condition or takes other medicines or supplements.
- If you’re not sure which product or dose to use, or how much formula counts as enough.
- If your baby may have had more than one dose in a day. In the US, you can call Poison Control at 1-800-222-1222.
- If your baby has signs the FDA links to too much vitamin D, such as vomiting, loss of appetite, increased thirst, frequent urination or not growing well.
- If your baby vomits often, feeds poorly or has fewer wet diapers than usual, whatever the cause.

Frequently asked questions
Do formula-fed babies need vitamin D drops?
Not if they drink 32 ounces or more of infant formula a day, according to the CDC. If your baby drinks less, or gets both breast milk and formula, the AAP advises a 400 IU supplement. Read more in our guide to moving from breast milk to formula.
If I take vitamin D, does my breastfed baby still need drops?
The NHS says breastfed babies should have a daily vitamin D supplement whether or not you take one yourself. If you have questions about your own supplements, ask your doctor or your baby’s pediatrician.
Is 400 IU the same as 10 micrograms?
Yes. US labels usually show IU and UK labels usually show micrograms. 400 IU of vitamin D equals 10 micrograms.
Can I just give my baby a multivitamin instead?
Check with your pediatrician first. Many infant multivitamins contain other vitamins too, and the dose of vitamin D can differ. The AAP and CDC guidance is about getting 400 IU of vitamin D a day.
Do babies on solid foods still need drops?
Usually, yes, until 12 months, if they’re breastfed or drink less than 32 ounces of formula a day. Food can add some vitamin D. The AAP lists fortified foods such as cereal and yogurt. See our nutrient-rich foods for babies guide.
