During the transition from hospital to home and up to the first four months from due date, premature infants spend less time awake, and when they are awake, they are less alert and may be more fussy. When they sleep, they sleep for shorter periods of time (shorter sleep-wake cycles) and awaken to fuss before they go back to sleep at night.
从医院过渡到家中，直至预产期后的头四个月，早产儿清醒的时间较少，而且当他们清醒时，警觉性较低，可能更容易烦躁不安。他们睡觉时，睡眠时间较短（睡眠-清醒周期较短），夜间在重新入睡之前会醒来烦躁一阵。
