Understanding Your Baby’s Sleep Patterns

Like a baby

How much sleep your newborn needs

Sleep plays an incredible part in your child’s development. Learn about the impact of environmental factors on your baby’s sleep, and how you can encourage positive sleeping habits early on with the help of our baby sleep expert Chireal Shallow.

One of the biggest adjustments for new parents is sleep, or essentially lack of it. Sleep deprivation goes hand in hand with parenthood; as a mum (or dad) with a newborn you’ll soon realize that the amount of sleep you get depends on your baby. You may want to curl up under your duvet, but your baby needs feeding, burping, changing, or even just a cuddle (or two) in the middle of the night. It may feel like your baby is awake more than they are asleep. But babies sleep, a lot! By the end of their first year, infants will have spent well over half their lives sleeping.1 And you’ll be glad they do, as sleep is associated with numerous aspects of baby brain development, and can significantly impact behavior, mental health and well-being.1

What role does sleep play for a newborn?

Sleep is often considered a passive activity, when in fact it is an active process. Despite the limited waking hours available for your baby to explore, there’s still plenty going on while they sleep. Infant sleep differs from adults, and the unique characteristics of your newborn’s sleep may promote learning.2 Your baby’s brain is developing and maturing, preparing them to process and explore the environment.2 Research has shown that babies learn and process responses to the world around them whilst sleeping.2

Sleep plays a role in the formation of memories, consolidating material that your baby saw and heard in the short time they may have been awake.2

What is ‘normal’ sleep?

You may think your baby never sleeps; or maybe they sleep too much just at the wrong times (those of you with night owls will exhaustedly agree). But let’s consider what ‘normal’ sleep is. Babies sleep patterns develop very quickly over their first twelve months of life.1 Newborns can sleep for up to 18 hours a day2, with night sleep duration increasing steadily. After a few weeks you will find your baby is awake for longer periods, and consequently sleeps for longer episodes,3 with night wakings also reducing.1 However all babies differ. Some sleep more than others. Some for longer periods, others in shorter bursts. Some babies sleep through the night early on, while others take much longer (if they get there at all).

It’s easy to consider sleep as an isolated behavior – your baby is either awake or asleep. But there are different states of consciousness through which your baby cycles several times a day. Two are sleep states; babies spend 50% of their time in each of these states:3,4

  • Active Sleep (also known as REM [rapid eye movement] sleep): breathing becomes more regular, your baby may startle at some noises
  • Deep Sleep (sometimes referred to as quiet sleep or Non-REM sleep): Baby lies quietly without moving; twitching and other movements stop

There are also waking or ‘active states’:4

  • Drowsiness: Baby’s eyes start to close; and they begin to fall asleep
  • Quiet Alert: Baby’s eyes open wide, their face is bright and body is quiet
  • Active Alert: Their face and body move actively
  • Crying: Baby cries, perhaps screams; their body moves in very sporadic ways

Learning about infant states and cues is important as it helps you become more aware and responsive to the subtleties of your baby’s sleep patterns.3

How do environmental factors affect your baby’s sleep?

Although there are general patterns of infant sleep, not all babies follow the same nocturnal example.

Studies have shown that sleep environment, mother-baby interaction, and feeding schedule can all impact the development of a baby’s sleep pattern.3 In addition, a carer’s temperament and stress levels are a key influence on a baby’s sleep. Negative temperament has been associated with sleep problems and night wakefulness, and maternal stress linked to day sleep duration, suggesting infant and maternal characteristics affect sleep differently.1

Establishing positive sleeping habits

With sleep evading you, and exhaustion setting in, you may feel like you will never get a good night’s sleep again. But there are a number of behavioral interventions you can put in place to help establish positive sleeping habits in your baby, such as encouraging your baby to self-soothe. The ability to self-soothe when falling asleep (settling to sleep at the beginning of the night and getting back to sleep if they wake during the night) appears to be a key ingredient for the development of healthy sleep-wake patterns.5

Babies who self-soothe are generally considered to be better sleepers than those who consistently need assistance to make the wake-sleep transition.5 Self-soothing can be supported by establishing a sleep routine for your baby, particularly daytime sleep habits. Day time sleep is thought to improve night time sleep and development of routines for sleep time, feeding, and bathing.3

It helps to be consistent with where you settle your baby. Whether in a crib, cot or co-sleeping with your child in your bed, providing a sense of permanence in where your baby sleeps will encourage a better sleep pattern.3

Also consider swaddling. Though not all babies enjoy being swaddled (snugly wrapping up your baby to help them feel safe and secure), there are benefits in doing so. Research studies have found that swaddling can calm and soothe babies, help them sleep, and help babies settle on their backs, preventing them turning on to their front or getting their heads covered by bedding.6,7


If you’ve ever heard the old adage ‘sleeping like a baby’ you might question its relevance, given how unsettled newborns can be in the first few months of life. For newborns, sleep occurs around the clock, with the sleep-wake cycle dependent on the need to be fed, changed and cuddled. But sleep isn’t just a passive activity. You may think your baby is dreaming about their next feed, but clearly there is a lot going on inside their head whilst they sleep.

Breastmilk is the ideal food for infants: it is best adapted to their specific needs. A healthy and balanced diet of the mother is important for the preparation and continuation of breastfeeding. Mixed breastfeeding can interfere with breastfeeding and reduce milk production. It’s hard to reverse the choice of not breastfeeding. If an infant formula is used for a non-breastfed baby, it is important to carefully observe the instructions for preparation and use and to follow the advice of the medical profession. Incorrect use could pose a risk to the child’s health. Socio-economic implications must be considered in the use of infant formula. After 6 months, in addition to breastmilk, water is the only essential drink. Do not hesitate to consult your health care professional if you need advice on feeding your baby.
