Studies of the differing means of definition problems of parturition and neonatal dependence, the extent of human variability underlying them, and the possibilities for enrichment of experience in early human interaction call into question such standard practices as isolation of the newborn, separation of mother and infant immediately after birth, and division of the family unit at the very time when it is symbolically and in reality becoming a family unit.
关于分娩和新生儿依赖定义问题的不同方式、其背后人类差异的程度以及早期人际互动中丰富经验可能性的研究，对诸如新生儿隔离、出生后立即将母婴分离以及在家庭单位在象征意义和实际意义上刚刚成为一个家庭单位之时就将其拆散等标准做法提出了质疑。
