Babies need a lot of sleep because they have so much new information to process and they are growing and developing at such a fast pace.

Night-time waking

If your baby keeps waking up at night it can become very tiring. Night waking in the early weeks and months is normal newborn behaviour. Most babies are unable to sleep through the night — particularly those younger than 12 weeks. Young babies have small stomachs so they need to spread their feeding over a 24-hour period. However, as babies grow they tend to sleep for longer periods at night.

While for adults about four-fifths of sleep is deep sleep at night; babies spend more time in light sleep. This means they can wake up more easily than adults.

Understanding day and night

At first, babies don’t know that night-time is for sleep and day-time is for being awake. They gradually develop this knowledge over the first few months but early on you may find your baby waking too early or at night. By the age of three to six months, and sometimes earlier, patterns begin to emerge with day-time naps becoming increasingly shorter and night-time sleeps longer. Babies’ sleep can also be affected by exposure to daylight and their body temperature. Time spent in daylight, especially the afternoons, seems to help babies to sleep longer at night.

Sometimes parents are encouraged to keep their babies awake during the day so that they will sleep better at night — but the results of this are variable, and difficult to be sure of, especially as babies change their sleeping and waking patterns as they grow, whatever you do. Preventing a tired baby from sleeping can be stressful in itself, as they may cry and fuss, and drop off to sleep anyway! 

Clock changes - daylight saving time

When it comes to the clock changes – in spring and in autumn – some parents prepare for this a week or so in advance. If your baby or toddler is in a predictable sleeping routine, you might want to adjust it by 10 or 15 minute increments each evening and morning. Keep the room where your baby sleeps darker, so they are unaware of, and unstimulated by, the brighter evenings or mornings when the clocks change. 

Some people just keep to the same times and alter daytime naps or have lots of fresh air and exercise the day before the clocks change. If your baby is an early riser you may need to take a nap in the day or go to bed earlier yourself.

Usually any disruption caused by the clock change will be temporary and even if you do nothing they will naturally adapt to the new time over a few days.

Encouraging sleep

If your baby won't sleep alone and you want to encourage your baby to sleep on their own, you could try one or more of the following:

  • Place them sleepy, but awake, in their cot at bedtime with a favourite toy.
  • Introduce a regular bedtime routine, such as a bath, or reading a book together.
  • Turn down the light and minimise talking, playing and disturbance when your baby wakes during the night.
  • Try to encourage continuity in their sleep by ensuring your baby rests in the same place the majority of the time. If you find that your baby won’t sleep in their cot, don’t be dissuaded. Keep going with your routine and try applying the above tips until they become comfortable with it. 

During the early weeks and months, some babies need more help than others to soothe themselves and fall asleep.

Sleep training approaches

Some parents explore sleep training approaches to encourage a regular sleeping pattern. This can be because they want to introduce a routine or because their baby has got into the pattern of waking frequently.

Sleep training often involves putting a baby down at regular times to go to sleep on their own. Parents may then leave the room and not return — this is often referred to as leaving baby to ‘cry it out’ and is only a last resort for older babies. Others check on their baby at regular intervals possibly offering reassurance, such as talking softly or making physical contact, but not pick their baby up —this is sometimes known as controlled comforting. Parents may also choose to stay in the same room as their baby.

‘Crying it out’ is seen as controversial by some healthcare professionals. Many parents find it distressing to leave their baby to cry. Concerns have been raised about the long-term effects of this approach, especially for very young babies. This is because there is evidence that leaving babies to cry increases their stress levels and is the opposite of the instinctive response of going to a crying baby. However, studies around controlled comforting approaches show no change or modest improvements to babies’ mental health when used with babies aged four months and older.

If you do want to try sleep training, it’s not suitable for very young babies. Its also important to be realistic about how often and why your baby wakes frequently. If you’re concerned you can see your GP about physical or medical reasons for frequent night waking, such as reflux, before trying any sleep training methods.

Safe sleeping guidelines

The risk of cot death or Sudden Infant Death Syndrome (SIDS) is increased:

  • For premature or small-for-dates babies.
  • By smoking during pregnancy or anyone smoking in the baby’s presence.
  • Using a duvet or pillow for a baby under one year old.
  • Sleeping with another child.
  • Sleeping with an adult who has been smoking, drinking alcohol or taking any drugs which cause drowsiness or affect depth of sleep.

Sleeping on a sofa or any other soft surface also carries much higher risks for your baby. There are also safe sleeping guidelines depending on where your baby sleeps. Read more about co-sleeping safely with your baby, bedside sleeping and sleeping safely in a cot. 

Your own sleep

Having your sleep disrupted or going without sleep when your baby keeps waking up can be physically and emotionally draining. And sometimes, it might feel like your baby just doesn’t want to sleep, despite everything you try. If you have disturbed nights, getting through the day can be more difficult. However, it is important to keep in mind that this period of sleep disruption won’t last forever.

If you can arrange times when you can catch-up on sleep during the day and allow yourself to leave non-essential jobs undone in the early weeks at least, you may find it easier to cope.

If you are finding it difficult to sleep when your baby sleeps even though you feel exhausted, talk to your health visitor or your GP, as although this is common, it could be an indication of postnatal depression.

Bedtime

Most babies will develop a regular sleep pattern over time, although these will continue to change as they grow. Eventually, you will probably find that they have a regular bedtime so you can finally get that longed-for night’s sleep.
