Supplement breastfed infants with 400 IU vitamin D daily
Provide 400 IU of vitamin D daily from birth for breastfed or partially breastfed infants; reassess after 12 months when the target increases to 600 IU.
📚 Based on Official Guidelines:
Recommended
- Start vitamin D drops soon after birth for exclusively or partially breastfed infants
- Review dosing at well-child visits once the child reaches 12 months
- Demonstrate proper administration (onto nipple or inside cheek)
Avoid
- Do not exceed recommended doses without clinician guidance
- Do not assume formula-fed infants need supplementation if intake already provides 400 IU
Why it matters: Vitamin D supports bone and immune health; breast milk alone does not meet the requirement.
