Abstract

Twin studies are important for research on genetic and environmental influences on child development, but it is imperative to test whether findings can be generalised from twins to singletons. Since the first months of life are defined by the emergence of important sleep behaviours, we compared 451 (54.8% females) twins and 77 singletons (48.1% females) on a range of sleep, settle and crying behaviours at 5 months of age. No significant differences were found regarding duration of crying or time until settled. However, singletons were reported to wake up more frequently during nighttime than twins (F(1, 509) = 35.10, p < 0.001, ηp2 = 0.065), suggesting that, when reported in twin studies, this measure might be slightly underestimated at a mean level in relation to singletons. In conclusion, despite the unique challenges and additional caregiver load of infant twins, there seem to be few differences between twins and singletons regarding parent‐reported settle and crying behaviours in early infancy.

双胞胎研究对于研究遗传和环境对儿童发育的影响非常重要，但当务之急是检验研究结果能否从双胞胎推广到单胎。由于出生后的头几个月是重要睡眠行为出现的时期，因此我们对 451 对双胞胎（54.8% 为女性）和 77 对单胎（48.1% 为女性）在 5 个月大时的一系列睡眠、安顿和哭闹行为进行了比较。结果发现，双胞胎在哭闹持续时间或安顿时间方面没有明显差异。不过，据报道，单胎婴儿夜间醒来的次数比双胞胎婴儿多（F（1，509）= 35.10，p < 0.001，ηp2 = 0.065），这表明在双胞胎研究中，这一指标的平均水平可能会略微低估单胎婴儿。总之，尽管双胞胎婴儿面临着独特的挑战和额外的照顾负担，但在父母报告的婴儿早期定居和哭闹行为方面，双胞胎和单胎婴儿之间似乎没有什么差异。
