Numeric rating scales will be used to measure the effect of the possible mediating variables, i.e., pain and stress. Potential confounding variables will be controlled by stratified randomization and exclusion criteria or monitored during the study period. Treatment expectation and satisfaction toward AT will be assessed in order to examine their relationship with therapy outcomes. Main components of study feasibility, i.e., recruitment, retention, and acceptance, will be evaluated. Participants also will be contacted to acquire their one and three-month breastfeeding practice status.
