The sucking rhythms of infants with a benign perinatal course are compared to those of infants with a history of perinatal distress. The ontogenesis of sucking rhythms, and the sucking patterns of children with major congenital malformations of the brain and various metabolic disorders are described. The analysis of rhythms of non-nutritive sucking discriminates to a statistically significant degree between normal infants and infants with a history of perinatal distress who have no gross neurological signs.
