The American Academy of Pediatrics (AAP) recommends infants be fed breast milk (also known as human milk) exclusively for the first 6 months after birth. Human milk contains a natural balance of vitamins, especially C, E and the B vitamins. So, if you and your baby are both healthy, and you are well nourished, your child may not require any supplements of these vitamins. However most infants need vitamin D supplements.

What is vitamin D?

• A vitamin important for many aspects of your child’s health, such as:
  • building strong bones.
  • having a strong immune system to fight infections.  
  • good mental health.
  • It might play a role in preventing cardiovascular disease.

Where does vitamin D come from?

• 400IU of vitamin D are recommended for babies up until 1 year of age.  
• Breastmilk is not a good source of vitamin D. This means that all breastfed infants should be given vitamin D supplements.  
• All formula-fed infants who take less than 1000ml (approximately 33 ounces per day) should also be given vitamin D supplements.  
• Vitamin D supplements are available over the counter and should be given once daily.
• There are 2 main types of vitamin D drops available for babies.  
  • Some preparations of vitamin D contain the recommended amount of vitamin D (400IU) in just one drop.  
  • Other preparations require you to give the entire dropper. Make sure to use the dropper that came with the bottle.  
  • Be sure to check the packaging of the vitamin D supplement you have to be sure you are giving the correct amount.

When to call your primary care provider?

• You have other questions or concerns.
