养儿育女在美国曾完全被当成母亲的职责。但近二十年来,心理学家与儿童发展专家逐渐发现,父亲分担育儿职责,对儿童的健康成长发育起着重要作用,某些作用甚至是母亲无法替代的。因此,父亲分担育儿职责因而成为一种时尚,在关心子女成长的中等收入家庭中尤为风行。 Child-raising in the United States has been completely as a mother’s responsibility. However, for nearly two decades, psychologists and children’s development experts have found that fathers share responsibility for childcare and play an important role in the healthy growth and development of children, and some can not even be replaced by their mothers. Thus, the sharing of parental responsibilities with fathers became a fashion and was particularly prevalent among middle-income families concerned with their children’s growth.
