Daytime sleep and wake periods of ten swaddled infants were periodically recorded by their mothers. The babies were swaddled above the waist for the first four days of the second, third and fourth months of life. During the next four days of the same months, the same infants were monitored with no swaddling. Comparison of the two sleep situations (swaddled and unswaddled) demonstrated that the increase in the total daytime sleep was statistically significant when the baby was loosely swaddled above the waist.
十位母亲定期记录了十名襁褓中的婴儿白天的睡眠和清醒时段。这些婴儿在出生后的第二个月、第三个月和第四个月的头四天里，腰部以上被包裹起来。在同一月份接下来的四天里，对相同的婴儿进行监测，不进行包裹。对两种睡眠情况（包裹和未包裹）的比较表明，当婴儿腰部以上被宽松包裹时，白天总睡眠时间的增加具有统计学意义。
