What is Vitamin D and why does my baby need it?
Vitamin D is needed to support healthy bone development, among other important benefits. When the body does not have enough vitamin D, bones can become weak and deformed, a condition called rickets. Vitamin D deficiency rickets among breastmilk fed infants is rare, but it can occur if an infant does not receive additional vitamin D from foods, exposure to sunlight, or a vitamin D supplement. Breastmilk is the only food babies need for the first 6 months of life, but because most adults in North America have low vitamin D levels, breastmilk often does not contain enough vitamin D for babies.
How do I make sure my baby gets enough Vitamin D?
One way to get more vitamin D is through direct sun exposure. However, because we are concerned about sun burns and increased risk for skin cancer, we believe it is safer to keep your baby covered from the sun with a hat and clothing. For babies who are being fed all or mostly breastmilk, a daily vitamin D supplement starting shortly after birth is recommended.
How can I give my baby Vitamin D supplements?
-
Vitamin D Supplements for Baby: If you choose to give your baby vitamin D directly, it is recommended to give 400IU (International Units) once each day. Vitamin D supplements are in a liquid form and can be purchased in the baby aisle of most grocery stores or pharmacies.
-
Concentrated drop – Each drop of a concentrated vitamin D contains the necessary 400IU, making it a convenient way to get your baby the vitamin D they need. You can put one drop on your clean finger, on the nipple before latching, or on a pacifier before putting it into your baby’s mouth.
-
1mL droppers – These vitamin D supplement bottles come with a dropper that holds 1mL to provide the daily recommended 400IU. You can squirt a whole dropper full into your baby’s mouth once per day. They may not like it at first, but they will get used to it in a few days.
-
Maternal Vitamin D Supplements: You can increase your own levels of vitamin D, so that your baby will get an adequate amount through your breastmilk. The dose of vitamin D recommended for breastfeeding parents is 6400IU daily to provide sufficient levels to baby. We recommend discussing your own individual needs with your health care provider.
When can I stop giving Vitamin D supplements?
You may stop the Vitamin D supplements for your baby once they start drinking cow’s milk or other Vitamin D-containing milk at 12 months old. If your baby takes more formula than breastmilk, they do not need Vitamin D supplements. In some situations, continuing to provide Vitamin D supplements is recommended into toddlerhood and beyond.
