Nature designed human milk especially for human babies, and it has several advantages over any substitute ever developed. Breast milk contains just the right balance of nutrients, and it contains them in a form most easily used by the human baby's immature body systems. Because it was developed for the human baby, breast milk is also the most gentle on your baby's systems.
Exclusively breast-fed infants should be supplemented with vitamin D within the first few days of life. Consult your infant's physician regarding supplementation.
