The purpose of this study was to identify the effectiveness of sensory stimulation program administered by primipara on the physical growth and mother-infant feeding interaction for the first 6 months of infancy.

Data were collected from December 1, 2001 to June 30, 2003. A total of 35 mothers and their infants were assigned to a control(n=17) and an experimental(n=18) group. Mothers in the experimental group received education related to sensory stimulation program and administered to their infants twice a day for 6 months. Both groups were measured the weight, length, head circumference and chest circumference of infants at 6 weeks, 10 weeks, 14 weeks, 18 weeks, and 22 weeks and the mother-infant feeding interaction at 6 weeks, 10 weeks through the home visiting.

Compared to the control group, the experimental group had significantly larger increases in head circumference for intervention period. In addition to, the experimental group showed significantly higher score in mother-infant interaction than control group.

These data suggested that sensory stimulation program administered by primipara may improve the physical growth of full term infant and mother-infant feeding interaction.
