Breast milk contains only low levels of vitamin K, and it may take weeks to months for the infant’s ‘sterile’ gut to become established and functional. Infants are therefore predisposed to having low vitamin K levels, resulting in low levels of vitamin K-dependent clotting factors, and an increased risk for bleeding, termed vitamin K deficiency bleeding.
