Cross-cultural studies suggest that children who sleep in the same room as their parents and who are breast-fed are less likely to use an attachment object. The present study examined childrearing practices that emphasize physical proximity of parent and child and use of an attachment object and thumbsucking at bedtime with 126 healthy U.S. infants. Four child-rearing practices were focused on: presence or absence of a caregiver when the child actually fell asleep; mode of feeding; location of the child's bed or sleeping place; whether or not the child slept with the parents during the night. Children who had an adult present as they fell asleep were less likely to use an attachment object or suck their thumbs. In contrast to cross-cultural research, the results of the present study suggest that where a child sleeps during the night or how the child is fed is not as important an influence on the bedtime use of an attachment object or thumbsucking as whether an adult is present as the child actually falls asleep.
跨文化研究表明，与父母同室睡觉且母乳喂养的孩子使用依恋物品的可能性较小。本研究对126名健康的美国婴儿进行了调查，考察了强调亲子身体亲近、依恋物品使用以及睡前吮拇指的育儿方式。研究重点关注了四种育儿方式：孩子实际入睡时照顾者是否在场；喂养方式；孩子床或睡觉地点的位置；孩子夜间是否与父母同睡。入睡时有成年人在场的孩子使用依恋物品或吮拇指的可能性较小。与跨文化研究不同，本研究结果表明，孩子夜间睡在哪里或如何喂养，对睡前使用依恋物品或吮拇指的影响，不如孩子实际入睡时是否有成年人在场那么重要。
