Everybody knows that when you have a baby, you are in for many sleepless nights. This is especially the case when your baby is a newborn. Don't expect your newborn to sleep through the night, as they need to be fed frequently, even when most people would be sleeping. Two or three hours is probably the longest stretch of time your newborn will go without waking up and crying to be fed (per What to Expect).

众所周知，当你有了一个孩子，你会有很多不眠之夜。尤其是当您的宝宝是新生儿时。不要指望你的新生儿整夜都在睡觉，因为他们需要经常喂食，即使大多数人都在睡觉的时候。两三个小时可能是你的新生儿不醒、不哭着要喂食的最长时间。

Between 2 and 3 months, your baby will be able to sleep for up to 6 hours at a time. At around 4 months, your baby should be able to sleep for up to 8 hours at a time, but may still expect a night-time feeding despite not technically needing one. According to What to Expect, it isn't until 5 or 6 months that you can reasonably expect your baby to sleep through the night. So what if yours isn't doing so?

在2到3个月大的时候，您的宝宝一次最多可以睡6个小时。在大约4个月大的时候，你的宝宝应该可以一次睡8个小时，但是尽管严格来说不需要，但你可能仍然需要晚上喂食。直到5个月或6个月大，你才可以合理地期望你的宝宝睡上个整夜觉。那么，如果你的孩子没有这样做呢?

If your baby isn't sleeping through the night after they reach the six-month mark, it is probably normal. In fact, a 2018 study published in Pediatrics found that 57% of 6-month-olds don't sleep a full 8 hours, and neither do 43% of 12-month-olds.

如果你的宝宝在六个月大的时候没有睡整夜觉，也可能是正常的。事实上，2018年发表在《儿科学》上的一项研究发现，57%的6个月大的孩子睡不到8个小时，43%的12个月大的孩子也睡不到。

While it is normal for babies (and even adults) to wake up a few times during the night, they should generally be able to self-soothe and go back to sleep. If your baby cannot, What to Expect recommends looking into sleep training. Other potential reasons your baby may wake up in the middle of the night include teething, growth spurts, and illness. Your baby may also be experiencing a phase of sleep regression, which is normal and temporary. Meanwhile, if your baby is currently learning a new skill such as crawling, they may be too excited to sleep.

虽然婴儿(甚至成年人)在夜间醒来几次是正常的，但他们通常应该能够自我安慰并重新入睡。如果你的宝宝不能，那么建议你进行睡眠训练。你的孩子可能在半夜醒来的其他潜在原因包括出牙、成长和疾病。您的宝宝也可能正在经历睡眠衰退阶段，这是正常和暂时的。同时，如果你的宝宝正在学习一项新技能，比如爬行，他们可能会兴奋得睡不着觉。

Ideally, your 4-12 month-old should sleep for 12 to 16 hours per day, including naps. According to What to Expect, you can promote restful sleep by keeping your baby in a quiet, dark, comfortable environment with a temperature between 68 and 72 degrees Fahrenheit. Healthline recommends maintaining a consistent bedtime routine to get your baby into the habit of sleeping at a certain time.

理想情况下，你4-12个月大的孩子应该每天睡12到16个小时，包括小睡。你可以让你的宝宝保持在一个安静、黑暗、舒适的环境中，温度在68到72华氏度之间，从而促进宝宝的睡眠。Healthline建议保持一贯的就寝时间，让宝宝养成在特定时间睡觉的习惯。
