Although gender equality is commonly found globally, many countries in Asia still show stereotypical gender roles within family relationships between fathers and mothers. In those countries, most stay-at-home mothers are mainly responsible for childcare and housework while fathers work so that some stay-at-home mothers are highly stressed by single childcare. To relieve their parenting stress, emotional support from their spouse is an important factor. However, working parents in single-income families tend to underestimate the childcare difficulties of their spouses. In this work, we propose Bodeum, a proof-of-concept mobile system to facilitate spousal communication by sharing stay-at-home parent's stress level, their childcare activities, and their baby's status with working parents to encourage emotional support for stay-at-home parents. A 2-week feasibility study with nine families in South Korea suggests that Bodeum enhanced spousal communication about parenting stress and showed potential for parenting mothers to lower their perceived parenting stress.
