title: Left-side preference for holding and carrying newborn infants. Parental holding and carrying during the first week of life.
abstract: Four groups of adults were studied: new mothers, new fathers, fathers with older children, and males without children of their own. Nearly 80 per cent of all newly delivered mothers and fathers held their newborn infant against a point to the left of the body midline. Handedness and parity did not influence this preference, nor did the sex of the infant. The present study also demonstrates that new fathers during the neonatal period, as well as fathers with older infants, display a significantly greater preference for holding the infant to the left than males without own children and with or without experience of other children. Individual mother-father pairs held the infant on the same side of the body in the majority of couples studied. The pattern of infant-carrying showed no significant in-between group differences. The possible significance of these observations and their relation to other parental behavior are discussed.
