The holding of 465 Japanese infants by their mothers was longitudinally observed at 4 and9 months with several checkups and questionnaires of physical and psychological development and child-care attitude in a larger longitudinal study of mother–child relationships. Aleft side bias in holding was significant for the 4-month-old infants. The infants’ increasedautonomy in their ability to adopt a posture at 9 months weakened the holding bias. Themothers’ handedness was related to different right/left hand contact patterns, but it wassignificant only for holding on the left side. The infants’ reflexes relating to posture did notcorrelate with the holding bias at 4 months. The meaning and possible determinants ofholding laterality are discussed.
