When infants are in their crawling stage, both mothers and infants experience difficulties while changing diapers. We evaluated the effects of pull-up type diaper on physical and psychological burden in comparison to the nappy-type diaper. Twenty-four mother-infant dyads participated in this study. According to the behavioral observation analysis, negative behaviors of mothers and infants while changing pull-up type diapers were significantly lesser than while changing the nappy-type. Pull-up type diapers took mothers 30% lesser time to change, while allowing infants more physical movements than the nappy-type. A spectral analysis of infants' heart rate variability showed that low-high frequency ratio and the change in normalized unit percentage (Nu%) were significantly lower when pull-up type diapers were changed. Negative emotion-related behaviors of both mothers and infants significantly correlated with change in Nu% of infants. Lower physical and psychological burden while changing diapers was associated with pull-up type diapers.
