Is it Ever a Good Idea to Wake a Sleeping Baby?

The arrival of a new baby most often leads to a huge amount of discussion among parents about sleep. While the demands of caring for a newborn can be overwhelming, one of the most perplexing dilemmas for new parents is whether or not it’s okay to wake a sleeping baby. Understanding infant sleep, circadian rhythms, and the guidelines provided by organisations like the NHS can be helpful in making informed decisions about your baby’s sleep.

In this post, I will explore the various aspects of waking a sleeping baby, offering guidance for new parents to ensure their baby gets the right amount of sleep while fostering healthy sleep habits in their children both in the early days and in the future.

Understanding Infant Sleep Patterns

Before delving into the question of whether it’s okay to wake a sleeping baby, it’s important to comprehend the intricate world of infant sleep patterns. Newborn babies spend the majority of their time sleeping, often up to 16 to 17 hours per day, during the first few weeks of life. The sleep patterns of infants, however, are markedly different from those of older children and adults.

Infant sleep is characterized by shorter sleep cycles, a greater percentage of deep sleep, and a higher frequency of waking throughout the night. These differences are not only normal but also essential for the baby’s well-being, helping to support essential functions such as growth, digestion, and cognitive development.

Circadian Rhythms and the Newborn

Understanding your baby’s circadian rhythm (the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment) is important in determining when to wake or not to wake a sleeping baby. Newborn babies are born without a circadian rhythm, which means their bodies are not yet trained to fall asleep regularly like adults. They usually sleep whenever they feel tired, as part of their body’s self-regulating or homeostatic response. This is why newborn and infant sleep patterns seem very erratic when compared to those of adults. This is also why waking a newborn to feed or change them will be unlikely to affect their ability to sleep well.

While newborns do not have a well-developed circadian rhythm in the early weeks of life, it begins to emerge around 2-3 months of age. This is when you can start implementing a more structured sleep schedule and encouraging the differentiation between day and night sleep. This is also the stage at which it’s not such a good idea to wake a baby during the night, unless absolutely necessary.

During the first few months, your baby may have long periods of deep sleep during the day and night. It’s essential to provide a consistent sleep environment and adhere to a bedtime routine to help establish a strong circadian rhythm, which will eventually lead to more prolonged nighttime sleep and less daytime sleep.

NHS Recommendations

The NHS provides guidelines for infant sleep and emphasizes the importance of sleep safety. These recommendations should be strictly adhered to and should also be the foundation for any decisions related to your baby’s sleep:

1. place your baby on their back to sleep, in the same room as you, for the first 6 months
2. keep your baby’s head uncovered – their blanket should be tucked in no higher than their shoulders
3. if wearing your baby in a sling or carrier, do not cover their head with the sling material or with a muslin
4. place your baby in the “feet to foot” position, with their feet at the end of the cot or Moses basket
5. do not let your baby get too hot or cold
6. never sleep with your baby on a sofa or armchair
7. do not smoke when you’re pregnant or around your baby after they’re born, and do not let anyone smoke in the same room as your baby

Is it a Good Idea to Wake a Sleeping Baby?

Now, let’s address the main question: Should you wake a sleeping baby? The answer largely depends on your baby’s age and specific circumstances. Here are some general guidelines to help you make the right choice:

1. Newborns (0-3 months): In the early days, waking a sleeping baby for feeding is generally recommended. Newborns need to feed every 2-3 hours, even if it means waking them from a deep sleep. This is crucial for their growth, birth weight, and weight gain. It is rare for such small babies to sleep for long stretches during the night, and if they do, then it is up to you to decide whether it is necessary to wake them up to feed them. If the baby is eating well in the day and gaining plenty of weight, you may decide you don’t need to.
2. Young Infants (3-6 months): As your baby grows, they may start to sleep for longer stretches at night. While it’s not necessary to wake them for nighttime feedings if they are gaining weight and feeding well, you should aim for consistent daytime feeds, naps and a regular bedtime routine to help with this.
3. Older Babies (6 months and older): Babies older than six months can generally sleep longer at night without waking for feedings. It is usually safe to let them sleep through the night. However, pay attention to making sure they get enough food throughout the day.
4. Premature Babies: Premature babies will often have different sleep needs and feeding routines to babies born at full term. Parents should follow their healthcare provider’s recommendations regarding feeding and sleep schedules.
5. Nap Transition (3-4 months): As your baby’s sleep patterns mature, they may start shortening or dropping daytime naps. At this age it’s not necessary to wake them from a long nap, but aim to time naps carefully so there is enough of an awake window between their afternoon nap (or last nap of the day) and bedtime.
6. Night Confusion (2-4 months): Some babies, especially newborns, experience night confusion where they have their days and nights mixed up. In such cases, it can be helpful to gently wake them from long daytime naps to encourage nighttime sleep.
7. Night Feedings (6 months and older): If your baby is older than six months and still wakes for night feedings, you might consider trying to night wean them. This is a very personal choice and all babies are different. Some will continue to need milk through the night much later than others. As your baby grows older, you may want to consider whether they really need to feed in the night, or whether they are doing it more out of habit or for comfort.

The Importance of Sleep Safety

When deciding whether to wake a sleeping baby, always prioritize sleep safety. Avoid placing your baby in a car seat, carrier, or any other device that is not designed for safe sleep. The risk of SIDS is higher when babies sleep in an adult bed, on a couch, or in an armchair. Use a safety-approved cot or bassinet for all sleep times, especially overnight sleeping.
Myths About Baby Sleep

There are numerous myths about baby sleep, and it’s important to separate fact from fiction. Some common myths include:

1. Babies should sleep through the night from day one: This is completely unrealistic. Babies have tiny stomachs and need frequent feedings in the early weeks.
2. A tired baby sleeps better: An overtired baby is often harder to settle. Overtiredness is a common reason for babies not sleeping well. Consistent sleep schedules and routines are key to promoting better sleep.
3. The later the baby’s bedtime, the better they will sleep: Once they are a few months old, babies who consistently have an earlier bedtime together with a consistent bedtime routine are more likely to sleep longer and wake less frequently than babies who go to bed very late.
4. Babies should be on a strict schedule: While routines are very important, flexibility is equally important. Every baby is unique, their needs and requirements regarding feeding and sleeping will regularly change and you should be adaptable to those needs.
5. Babies should sleep in complete silence: White noise can be beneficial for soothing a baby, as it mimics the sounds they heard in the womb. It’s also really useful to get babies used to sleeping around noise so they will be more adaptable to sleeping in different rooms/environments both at home and elsewhere.

Conclusion

In the first year of life, babies go through significant changes in their sleep patterns and needs. Deciding whether to wake a sleeping baby depends on their age, feeding schedule, and specific circumstances. Always prioritise sleep safety, following the guidelines provided by the NHS. As new parents, it’s important to be adaptable and responsive to your baby’s sleep needs, fostering healthy sleep habits while ensuring they get enough rest to grow and develop.

Remember that every baby is unique and that what works for one may not work for another. The good news is that with time, patience, and a good understanding of your baby’s sleep patterns, you can navigate the journey of parenting and help your baby establish healthy sleep habits that will benefit them and their families throughout their lives.
