The purpose of this study was to determine the differences between baby spas and baby massages for infants aged 6-12 months. This study used an experimental method with a sample of 20 babies consisting of 10 babies in the baby spa group and 10 in the baby massage group. Growth measurements are based on body weight and length while monitoring progress using the Pre Development Screening Questionnaire (KPSP). The results showed that the average difference in body weight after a baby massage was 9,020 grams and after the baby spa 10,580 grams were obtained with a p value of 0.002, while the average difference in body length after a baby massage was 74.90 cm and after the baby spa was 78.80 grams with a p value of 0.017 and the average development in the baby massage group was 8.95 lower than the baby spa group of 12.05, a p value of 0.121. The results of this study are expected to increase the knowledge of mothers about the importance of the Baby Spa to increase the growth (weight and length of the baby), while for the development of the baby can stimulate baby massage and baby spa.
