How Long Should A Newborn Sleep?

Sleep is an essential component in the development of a newborn, playing a significant role in their growth and well-being. The amount of sleep a newborn requires can vary, but generally, they should sleep between 14 to 17 hours a day for the first three months. Sleep durations will often occur in intervals of 2 to 4 hours throughout the day and night. This is because newborns have small stomachs and need regular feedings, making uninterrupted long sleep stretches difficult. As they grow older and start to develop a more regular sleeping pattern, these intervals will change.

Understanding Newborn Sleep Patterns

Newborns don’t yet have a sense of night and day, which is something they’ll start to learn over the first few months of life. This lack of a circadian rhythm means that their sleep can be erratic. The sleep cycle of newborns is divided into active sleep, where they might twitch or grimace, and quiet sleep, which is more restful and deep.

Active Sleep vs. Quiet Sleep

Active sleep, or Rapid Eye Movement (REM) sleep, is a lighter form of sleep where dreams typically occur. Newborns spend a greater portion of their sleep in the REM stage than adults do, which is believed to be important for the incredible development happening in their brain.

Quiet sleep, also known as Non-Rapid Eye Movement (NREM) sleep, consists of deeper sleep stages. During these times, a newborn’s body is growing and repairing itself, which is why it’s also sometimes referred to as “restorative” sleep.

Feeding and Sleep

Due to their rapid growth and small stomach capacity, newborns need to be fed frequently — about every 2 to 3 hours. This need for frequent nourishment is one of the main reasons for their short bouts of sleep. Breastfed babies may need to feed more often than formula-fed babies because breast milk digests faster than formula, which means they might wake up more often during the night.

Breastfeeding and Sleep

It’s important to note that while breastfeeding can require more frequent awakenings at night for feeding, it might also help the baby (and the parent) return to sleep more quickly. This is due to the presence of hormones like prolactin and oxytocin, which promote relaxation and bonding during nursing.

Formula Feeding and Sleep

On the other hand, formula-fed babies might have slightly longer stretches of sleep simply because formula takes more time to digest. However, it’s not recommended to overfeed or thicken formula to try to extend a baby’s sleep, as this can lead to digestive discomfort and other issues.

Sleep and Development Milestones

Babies often sleep more when they are going through growth spurts or periods of rapid development. These can happen at various times but are particularly common at around 2 weeks, 6 weeks, 3 months, and 6 months of age.

Changes to Sleep Duration

Around the 3-month mark, many babies start sleeping for longer stretches at night, which might be as long as 4 to 6 hours. As they approach the 6-month milestone, some babies are capable of sleeping through the night, which is usually considered a stretch of about 6 to 9 hours.

Creating a Safe Sleep Environment

Ensuring a safe sleeping environment for your infant is critical. Sudden Infant Death Syndrome (SIDS) is a concern in infants under a year of age, and following guidelines for safe sleep can reduce the risk.

SIDS Prevention Measures

Here are some ways to create a safe sleep environment for your newborn:
– Always lay your baby down to sleep on their back.
– Use a firm mattress with a fitted sheet that’s appropriate for the baby’s age and the size of the crib or bassinet.
– Keep toys, loose bedding, bumpers, and pillows out of the crib.
– Share a room with your newborn, but not the same sleeping surface, ideally for the baby’s first year, but at least for the first six months.
– Avoid overheating by keeping the baby appropriately dressed for the room temperature, and don’t cover the baby’s head.

Helping Your Newborn Develop Healthy Sleep Habits

While newborns do not have predictable schedules, there are ways parents can begin to encourage good sleep habits:

Establishing a Bedtime Routine

Creating a relaxing bedtime routine can signal to your baby that it’s time to wind down. This routine might include a warm bath, a gentle massage, quiet singing, or soft music.

Making Daytime Different from Nighttime

To help your baby learn the difference between night and day, make sure there’s plenty of natural light and activity during the day, and keep nighttime feedings and interactions quiet and subdued.

When to Seek Help

While variability in sleep is normal for newborns, there are times when you might want to reach out for help. If your baby seems excessively sleepy or if you’re having trouble waking them for feedings, or if they’re sleeping significantly less than 14 hours a day, it’s important to contact your pediatrician.

Excessive Sleepiness or Alertness

Any significant change in a newborn’s sleep patterns or a marked difference in their level of alertness and responsiveness should be discussed with a healthcare provider to rule out any medical concerns.

Finishing Thoughts

The early weeks with a newborn are as exhausting as they are exhilarating. It’s crucial to remember that each baby is unique and that sleep patterns can vary widely. Rather than focusing too much on exact numbers, aim to provide a safe, nurturing environment that’s conducive to sleep, and contact a pediatrician if you ever have concerns about your baby’s sleep habits or health. As the weeks progress, parents will often begin to notice more predictable patterns, and the joy of a sleeping newborn will become one of the many heartwarming memories of early parenthood.
