Pregnancy is a period of significant physical and psychological changes. Pregnant women often struggle with poor sleep quality which can increase the risk of developing depression and anxiety. Additional factors can affect sleep quality and vice versa. We focused on an understudied topic: pregnant women`s expectations about how their infant will sleep. This study aims to describe the potential correlates and predictors of women`s sleep quality and their expectations about child sleep in a broader context. In total, 250 women participated in the research. Participants completed questionnaires PSQI, MEQ, DASS-21 and BISQ-R. To verify the set aims, we used Pearson’s correlation coefficient, t-test and general linear model (GLM), including methods for determining the effect size (Hedges’ g, r², ε2). The results showed that sleep quality is related to circadian preference, depression, anxiety and stress. Women with poor sleep quality were more evening type and scored higher on these variables. Anxiety, circadian preference and the week of pregnancy were the most significant predictors of sleep quality. Women with at least one child and women who did not prepare for childbirth and motherhood and had not encountered information about a child’s sleep scored higher in BISQ-R. A hypothesis can be put forward that sufficient information before childbirth and earlier maternal experiences can affect expectations about a child’s sleep. This hypothesis would need to be verified in future research.

怀孕是身体和心理发生重大变化的时期。孕妇经常面临睡眠质量差的问题，这会增加患抑郁和焦虑的风险。其他因素也会影响睡眠质量，反之亦然。我们重点研究了一个未被充分研究的话题：孕妇对婴儿睡眠方式的期望。这项研究旨在在更广泛的背景下描述女性睡眠质量的潜在相关性和预测因素以及她们对儿童睡眠的期望。总共有 250 名女性参与了这项研究。参与者完成了 PSQI、MEQ、DASS-21 和 BISQ-R 调查问卷。为了验证设定的目标，我们使用了 Pearson 相关系数、t 检验和一般线性模型 (GLM)，包括确定效应大小的方法（Hedges' g、r ²、ε2）。结果表明，睡眠质量与昼夜节律偏好、抑郁、焦虑和压力有关。睡眠质量差的女性更倾向于晚睡型，并且在这些变量上得分更高。焦虑、昼夜节律偏好和怀孕周数是睡眠质量最重要的预测因素。至少有一个孩子的女性以及没有准备分娩和成为母亲以及没有接触过有关孩子睡眠信息的女性在 BISQ-R 中得分较高。可以提出一个假设，即分娩前的充分信息和早期母亲经历会影响对孩子睡眠的期望。这一假设需要在未来的研究中得到验证。
