If You’re Wondering Why Your Baby Doesn’t Sleep Through The Night, Read This
如果你想知道为什么你的宝宝一夜不睡，阅读这篇文章吧
1. Babies have shorter sleep cycles
婴儿有更短的睡眠周期
While adult sleep cycles last an average of 90 minutes, infant sleep cycles are shorter, lasting from 50 to 60 minutes. This is why they experience periods of night waking every hour or so.
而成人睡眠周期平均持续90分钟，婴儿睡眠周期更短，持续50至60分钟。这就是为什么他们在夜间每隔一小时左右就醒来的原因。
2. Babies wake up at night to get your attention
宝宝半夜醒来想得到您的关注
Babies may sleep better during the day because at night, they will get more attention from their two primary caregivers. During this period, there are fewer disturbances or interruptions to taking care of your child.
婴儿或许在白天睡得更好，因为到了晚上，他们想要从他们的两个主要照顾者身上获得更多的关注。在此期间，照顾你的孩子有较少的干扰或中断。
3. Babies don’t sleep as deeply as adults
宝宝没成人睡得那么沉
Not only do babies require a longer time to sleep and have more frequent waking periods during the night, they are lighter sleepers than adults.
婴儿不仅需要较长的睡觉时间，在夜间也会更频繁的醒着，他们比成人睡得更轻。
4. A newborn’s body clock is not set
新生儿的身体还没调好生物钟
Another reason why babies don’t sleep at night is that their body clocks are not set yet. We sleep at night and wake up in the morning because we have circadian rhythms; these cycles of rest and activity get synchronized to light and darkness. Although a baby’s internal clock is fully formed before he is born, his brain doesn’t respond to it until he is 2-5 months old.
宝宝晚上不睡觉另一个原因是他们的身体生物钟尚未调好。我们在晚上睡觉，早晨醒来，因为我们有昼夜节律;休息和活动的这些周期与白天和黑夜同步。虽然婴儿的内部时钟在他出生之前就已经完全形成，他的大脑在他2-5个月时才会对此作出回应。
5. They are adjusting to developmental milestones
他们正在调整发展里程碑
As your baby learns to walk, pull up, roll, crawl, talk, etc., their sleep can become disrupted (naps too). It is important that they get appropriate naps during the day to help them get plenty of sleep, even when their new skills keep waking them up.
随着宝宝学会走路，拉，滚，爬，说话等，他们的睡眠会被打乱（小睡也是如此）。白天得到适当午睡是很重要的，这可以帮助他们获得充足的睡眠，甚至保持他们学到的新技能。
6. Their desire to eat
他们想吃东西
This one may seem obvious, yet when a 5-month-old baby is waking at night for a feeding or two, it could become a cause for concern. It is important to read about night feedings and when to night wean so you can understand how to deal with this.
这一条似乎是显而易见的，然而，当一个5个月大的宝宝晚上醒来，喂食一两次，这可能会引起人们的关注。了解夜间喂奶和什么时候断奶是很重要的，所以你会知道如何处理。
