Data are median (interquartile range) or % (n). Data were missing on level of satisfaction with the husband's participation in childcare (n = 53), mother's frequency of playing with the child (n = 9), frequency of reading to the child (n = 7), frequency of taking the child out of the house (to somewhere other than the childcare facility) (n = 7), frequency of meeting other parents with the same-aged children (n = 8), frequency of talking about the child with husband (n = 13), availability of a caretaker other than the child's mother (n = 54), availability of those whom the mother can seek advice about childcare (n = 63), breastfeeding at 6 months after delivery (n = 46), breastfeeding at 1 year after delivery (n = 9), breastfeeding at 18 months after delivery (n = 20). Distribution normality was confirmed using the Shapiro–Wilk test. Calculated using the Mann–Whitney U test or Chi-squared test (2 × 2 groups).
