A randomly selected community sample of 303 parents of 2- and 3-year-olds were interviewed about child sleep behaviors and completed the Child Behavior Checklist for Ages 2-3, a standardized rating scale for child problem behaviors. Most parents (55%) reported that the child slept in their bed at least occasionally and for at least part of the night, particularly during periods of minor stress or disruption of the family routine. The prevalence of cosleeping did not vary by the child's age or sex, but frequent cosleeping (more than once per week) was more common among nonwhite families and single-mother households. Cosleeping was not significantly related to child behavior problems, but frequent cosleepers were more likely to report sleep problems, including difficulty getting to sleep and night waking. Children who were still cosleeping frequently 1 year after the initial assessment maintained high levels of sleep problems, compared with those who stopped cosleeping and non-cosleepers. Cosleeping is common at this age and is not related to general maladjustment. However, frequent cosleeping is closely intertwined with child sleep problems.
对一个随机抽取的由303名2至3岁孩子的家长组成的社区样本，就孩子的睡眠行为进行了访谈，并让他们填写了《2至3岁儿童行为清单》，这是一份针对儿童问题行为的标准化评定量表。大多数家长（55%）报告称，孩子至少偶尔会和他们一起睡，且至少睡上半夜，尤其是在家庭日常出现轻微压力或被打乱的时候。同睡的比例在孩子的年龄或性别上没有差异，但频繁同睡（每周不止一次）在非白人家庭和单亲母亲家庭中更为常见。同睡与孩子的行为问题没有显著关联，但频繁同睡者更有可能报告睡眠问题，包括入睡困难和夜间醒来。与那些停止同睡的孩子以及不同睡的孩子相比，在初次评估一年后仍频繁同睡的孩子存在较高程度的睡眠问题。在这个年龄段，同睡很常见，且与总体适应不良无关。然而，频繁同睡与孩子的睡眠问题紧密相关。
