... d the control group regarding the baby's weight gain before massage. Posttest will be conducted in both groups after the intervention is given. Results: The results of the normality test of the data with the Shapiro-Wilk test in the experimental group from each measurement and the increase showed that they were not normally distributed (p<0.05); while the control group whose data were normally distributed were on the 2nd Week, 3rd Week, and 4th Week measurements, while the others were not normally distributed. For comparison of the baby's weight from each measurement because the treatment group was not normally distributed, the statistical test used was a non-parametric test with the Mann-Whitney test. Conclusions The weight gain of infants aged 3 to 5 months in the intervention group who received massage was greater than in the control group who did not receive massage.
