许多家长把婴儿夜间频繁醒来理解为“没睡好”或养育出了问题。CUNY 研究生中心 2026-11-04 报道一项发展心理生物学研究：逾 200 名五个月至一岁婴儿在新动作与语言技能出现前后约一周，睡眠更易紊乱；语言里程碑关联是该路径上的新发现。阅读时可留意 disruption、milestone、duration、reorganization 等词，以及 may、suggested、cannot yet prove 如何保留研究边界。

Many parents lose sleep when a baby wakes again and again through the night. A new report from the City University of New York Graduate Center may offer a calmer reading of those restless weeks. Lead author Mali Waugh, a psychology doctoral student, and Professor Sarah Berger studied how infant sleep changes around the arrival of new skills. Their paper, published this summer in Developmental Psychobiology, links sleep disruptions not only to motor milestones but also, for the first time in this line of work, to early language milestones.

许多家长会因为宝宝一夜又一夜醒来而睡不好。纽约市立大学研究生中心（CUNY Graduate Center）的一份新报道，或许能让人更平静地看待那些不安稳的几周。心理学博士生、第一作者 Mali Waugh 与 Sarah Berger 教授研究了婴儿睡眠如何随着新技能到来而变化。他们今年夏天发表在《Developmental Psychobiology》上的论文指出，睡眠紊乱不仅与动作里程碑有关，也在这一研究路径上首次与早期语言里程碑联系起来。

The team followed more than 200 babies between five months and one year old in two age cohorts. Sleep and skill data were collected remotely through an online app and a baby-monitor system, while parents reported when new abilities appeared. The clearest sleep changes clustered in a window from about one week before a new skill showed up to about one week after it. Disruptions lined up with first crawling steps, first walking steps, walking mastery, babbling, cooing, expressive jargon, new-word use and object labeling. Analyses suggested that many skills were tied more strongly to shorter sleep duration than to extra night wakings: babies often took longer to fall asleep, or stayed awake longer after waking, rather than simply waking more often.

研究团队跟踪了两个年龄队列中、年龄在五个月到一岁之间的逾 200 名婴儿。睡眠与技能数据通过在线应用和婴儿监护系统远程采集，家长则报告新能力何时出现。最明显的睡眠变化集中在新技能出现前约一周到出现后约一周。紊乱与首次爬行、首次迈步、步行掌握、咿呀学语、咕咕发声、表达性乱语、新词使用和物品指称相对应。分析显示，许多技能与睡眠时长变短的关系，比与夜间醒来次数增加的关系更强：宝宝常常更难入睡，或醒来后更久才再睡着，而不只是醒得更勤。

Earlier studies had already connected motor skill onsets with tougher nights. Waugh said language had been far less studied; few longitudinal projects had checked whether babbling or first words also travel with sleep changes. Berger, who directs the Child Development Lab at the College of Staten Island, pointed to a possible explanation drawn from other research. Learning a new skill may involve neural reorganization; that reorganization may happen during REM sleep; and REM sleep is more easily broken by awakenings than other sleep stages. Put together, night unrest around a milestone may reflect the brain work of building a skill, not only a bad day or a poor sleep setup.

更早的研究已经把动作技能出现与更艰难的夜晚联系起来。Waugh 说，语言方面研究少得多；很少有纵向项目检查咿呀学语或最初几个词是否也会伴随睡眠变化。在史坦顿岛学院（College of Staten Island）主持儿童发展实验室的 Berger，引用其他研究提出一种可能解释：学习新技能可能涉及神经重组；这种重组可能发生在快速眼动（REM）睡眠期间；而 REM 睡眠比其他睡眠阶段更容易被唤醒打断。综合来看，里程碑前后的夜间不安，可能反映的是大脑在构建技能，而不只是糟糕的一天或糟糕的睡眠环境。

The study cannot yet prove that brain reorganization causes every restless night, and the team wants future work that records neural activity during those disruptions. Skill dates also relied on parent reports, so timing may not be perfect. For now, Waugh’s message to tired parents is practical. A baby who sleeps less for a while may be practicing something new. Watch for changes in movement or sound, and remember that the pattern need not mean poor parenting.

这项研究尚不能证明神经重组导致每一个不安之夜，团队也希望未来能在这些紊乱发生时记录神经活动。技能日期还依赖家长报告，时间点未必完美。眼下，Waugh 给疲惫家长的提醒很实际：一段时间睡得少些的宝宝，可能正在练习新东西。留意动作或声音上的变化，并记住这种模式不一定意味着养育不当。
