Human infants spend most of their time sleeping, but over the first few years of life their sleep becomes regulated to coincide more closely with adult sleep (Galland et al., 2012; Paavonen et al., 2020). Evidence shows that co-sleeping played a role in the evolution of infant sleep regulation, as it is part of an ancient behavioral complex representing the biopsychosocial microenvironment in which human infants co-evolved with their mothers through millions of years of human history (Ball, 2003; McKenna 1986, 1990). This paper is a conceptual, interdisciplinary, integration of the literature on mother-infant co-sleeping and other mother-infant co-regulatory processes from an evolutionary (biological) perspective, using complexity science. Viewing the mother-infant dyad as a "complex adaptive system" (CAS) shows how the CAS fits assumptions of regulatory processes and reveals the role of the CAS in the ontogeny of mother-infant co-regulation of physiological (thermoregulation, breathing, circadian rhythm coordination, nighttime synchrony, and heart rate variability) and socioemotional (attachment and cortisol activity) development.
人类婴儿大部分时间都在睡觉，但在生命的头几年，他们的睡眠会逐渐变得更规律，与成人的睡眠更为接近（Galland 等人，2012；Paavonen 等人，2020）。有证据表明，同睡在婴儿睡眠调节的进化中发挥了作用，因为它是一个古老的行为综合体的一部分，代表了人类婴儿在数百万年的人类历史中与母亲共同进化的生物社会心理微观环境（Ball，2003；McKenna，1986，1990）。本文从进化（生物）的角度，以复杂性科学为工具，对母婴同睡和其他母婴共同调节过程的文献进行了概念性、跨学科的综合。将母婴对子视为“复杂适应系统”（CAS），可以显示出 CAS 如何符合调节过程的假设，并揭示 CAS 在母婴对生理（体温调节、呼吸、昼夜节律协调、夜间同步和心率变异性）和社会情感（依恋和皮质醇活动）发展的共同调节的个体发生中的作用。
