Dr Dillard has interpreted our results as an attempt to show adverse effects of prolonged breast-feeding. In studying the less than 2-year-old vegetarians we found it necessary to note the effects of breast-feeding. The breastfed infants had reduced weight, but not length velocities. These velocities were compared to Harvard growth norms and a reduced weight velocity does not necessarily imply a health hazard.
What appears to be unique among this group is the extended breast-feeding and reduced weight gain velocity up to 2 years of age.
