How to promote ‘discipline without tough love’ during pregnancy: a randomized controlled trial

Background: In Japan, the effect of education using the leaflet ‘Discipline Without Tough Love’ on mothers during caring for their infants have been reported. We examined the effect of this education on pregnant Japanese women. Methods: : The present study was a prospective investigation of all Japanese women with singleton pregnancies who visited our hospital for a perinatal visit at 20-23 weeks’ gestation between November 2017 and March 2018 and gave birth at ≥ 37 weeks’ gestation at our hospital. We examined the maternal feelings (bonding situation) to babies of women who received the leaflet in comparison with that in women who did not receive it during the health check-up performed routinely at one month after delivery using the Japanese version of the Mother-to-Infant Bonding Scale. Results: : There were no significant differences in maternal feelings for their babies between the two groups of women. Conclusions: : We did not identify any effect of health consultations cased on ‘Discipline Without Tough Love’ during pregnancy on maternal feelings toward babies at one month after delivery. A further study to enlighten pregnant women about parenting without corporal punishment will be needed in Japan.
