Sudden unexplained and unexpected death in twins has not been well studied, particularly in relation to the common practice of sleeping twin infants together in the same cot (cobedding). Postal surveys of 109 mothers of twins were undertaken when the infants were 6 weeks, 4 months, and 8 months of age to determine the prevalence of cobedding, infant care practices related to sudden infant death syndrome (SIDS), and the mother's knowledge of SIDS risk factors. SIDS risk factor knowledge was similar to an earlier survey of singletons in 2005. At 6 weeks, 76% of infants usually slept on the back; this changed to 86% at 4 months and 73% at 8 months. At 6 weeks, 52% usually cobedded with their twin all or part of the time. At 4 and 8 months, this had reduced to 31% and 10%, respectively. Side-by-side cobedding configurations were predominant at 6 weeks, with feet-to-feet configurations increasing as the infants grew older. Breastfeeding was reported in 83%, 61% and 31% of infants at 6 weeks, 4 months and 8 months, respectively. Pacifier use was reported in 38%, 50% and 33% at the respective surveys. As the age of the twins increased, mothers were significantly more likely to be concerned about deformational plagiocephaly in Twin 1 than in Twin 2.
Despite a lack of evidence of the risks or benefits of cobedding, this practice was very popular, especially in the younger infants. More research is needed to establish the safety of cobedding in relation to the risk of SIDS.
双胞胎的突然不明原因和意外死亡尚未得到充分研究，尤其是与将双胞胎婴儿一起睡在同一张婴儿床（同床）的常见做法有关。当婴儿 6 周、4 个月和 8 个月大时，对 109 位双胞胎母亲进行了邮政调查，以确定同床的流行率、与婴儿猝死综合征（SIDS）相关的婴儿护理做法以及母亲对 SIDS 危险因素的了解。SIDS 危险因素知识与 2005 年对单身儿童的早期调查相似。在 6 周时，76%的婴儿通常仰卧睡觉；4 个月时变为 86%，8 个月时变为 73%。在 6 周时，52%的婴儿通常会与双胞胎同床共枕，全部或部分时间。4 个月和 8 个月时，这一比例分别降至 31%和 10%。在 6 周时，并排同床的配置占主导地位，随着婴儿的成长，脚对脚的配置增加。报告在 6 周、4 个月和 8 个月时，分别有 83%、61%和 31%的婴儿母乳喂养。在各自的调查中，报告使用奶嘴的比例分别为 38%、50%和 33%。随着双胞胎年龄的增长，母亲明显更担心双胞胎 1 出现变形性斜头畸形，而不是双胞胎 2。
尽管缺乏同床的风险或益处的证据，但这种做法非常流行，尤其是在较小的婴儿中。需要更多的研究来确定同床与 SIDS 风险相关的安全性。
