Head position preference in 15 low-risk pre-term infants studied in relation to conceptional age and nursing routines. A head position preference to the right is evident with respect to the head position imposed by the nurse. The observed spontaneous head position preference might be ascribed to the influence of the foregoing imposed head position, the influence of which diminishes with increasing observation time. After several spontaneous head turnings the low-risk pre-term infants show no head position preference anymore.
