摘要：Approximately 20%–30% of infants cry excessively and exhibit sleep difficulties for no apparent reason, causing parental stress and even triggering impulsive child maltreatment in a small number of cases.1, 2, 3, 4, 5, 6, 7, 8 While several sleep training methods or parental education programs may provide long-term improvement of infant cry and sleep problems, there is yet to be a conclusive recommendation for on-site behavioral interventions.9, 10, 11, 12, 13 Previously we have reported that brief carrying of infants transiently reduces infant cry via the transport response, a coordinated set of vagal activation and behavioral calming conserved in altricial mammals.14, 15, 16, 17, 18 In this study, we disentangled complex infant responses to maternal holding and transport by combining subsecond-scale, event-locked physiological analyses with dynamic mother-infant interactions. Infant cry was attenuated either by maternal carrying or by reciprocal motion provided by a moving cot, but not by maternal holding. Five-minute carrying promoted sleep for crying infants even in the daytime when these infants were usually awake, but not for non-crying infants. Maternal laydown of sleeping infants into a cot exerted bimodal effects, either interrupting or deepening the infants’ sleep. During laydown, sleeping infants were alerted most consistently by the initiation of maternal detachment, then calmed after the completion of maternal detachment in a successful laydown. Finally, the sleep outcome after laydown was associated with the sleep duration before the laydown onset. These data propose a “5-min carrying, 5- to 8- min sitting” scheme for attending to infant cry and sleep difficulties, which should be further substantiated in future studies.

如何让哭泣的婴儿停下来往往让父母们头疼不已。近日，一项发表在《当代生物学》上的研究发现了人类婴儿身上的一种“运输反应”，相比于仅抱着婴儿，抱着他们走动会更容易使他们安静下来。这为操心的父母给出了简单的解决方案：抱着婴儿走5分钟。



科学家用摄像机和心电仪记录下了当哭泣、平静清醒、熟睡的婴儿被母亲抱着静坐或行走、或在车中被推着走时的心率变化，发现婴儿对母亲的动作非常敏感，心率也会随之变化。当被抱着行走五分钟后，所有哭泣的婴儿都冷静了下来，心率降低，并有半数进入熟睡；而被抱着静坐的婴儿则继续大哭。不过，终于熟睡的婴儿被放下时也有时会突然醒来。基于心率数据，科学家建议先稳定地抱着哭泣的婴儿行走五分钟，再静坐八分钟，等他们进入稳定的睡眠状态后再放下来。
