Grantham-McGregor, S. M., and Back, E. H. (1970). Archives of Disease in Childhood, 45, 404. Breast feeding in Kingston, Jamaica. A longitudinal study was carried out on 300 Kingston infants born at the University Hospital of the West Indies. The method of milk feeding and the reasons given by the mothers for beginning bottle feeding were recorded. Other factors influencing the incidence of breast feeding were examined. Complementing in hospital, maternal employment, improving socio-economic status, advertising, and general misinformation were considered important. A higher incidence of gastro-enteritis was found in the first 4 months of life among partly or wholly bottle-fed babies than among breast-fed babies. Weight increments were calculated for the first 3 months of life. A higher proportion of infants with increments in the lowest 25% were bottle fed than those infants with increments in the remaining 75%o.

SUMMARY Some items of gross motor and language development behaviour were evaluated in 300 Kingston, Jamaica, infants of predominantly Negro extraction throughout the first year of life. They were found to be accelerated over the normal white child of the Gesell Developmental Schedules. Children of low birthweight were significantly slower than the remaining children in attaining several items but were equal to the normal white child of the Gesell Schedules. Sex and socio‐economic class made no difference to the age of walking, although high weight at 12 months had a beneficial effect.
