Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Women are qualified to participate if they are over 10 years of age, having singleton pregnancy, and are exclusively breast feeding and intending to exclusively breast feed for at least 10 more weeks. Exclusion Criteria: * Exclusion criteria include diabetes, cardiovascular conditions and liver disease prior to and during pregnancy because these diseases affect metabolism of several nutrients and thus may lead to differences in the MVI intake and nutrient status relationship.
