We have examined the growth charts for all 115 children (55 boys and 60 girls) who were born in 1978 and who, in January 1984, lived in the catchment area of a well-child clinic in Östersund, a small city in central Sweden. Seventeen children were formulafed (no breast-feeding recorded at age 2 months ± 10 days), 29 were mixed-fed (one breast meal or more at age 2 months ± 10 days; less than four breast meals at age 4 months ±2 weeks), 52 were breast-fed (four breast meals or more at age 4 months ±2 weeks; no formula before this age but "educational" portions of solids were permitted),
