When it comes to sleep, babies are like adults — some need more than others. Understand more about your baby’s sleep and how babies can learn to settle themselves to sleep.
Below is just a general guide to how much sleep a baby may need – your baby may sleep more or less than indicated here. They are individuals so don’t worry too much about the exact number of hours they sleep.
Approximate sleeping times for babies by age
|Newborn||Upwards of 16 hours, spread through the day with each sleep lasting 2-3 hours.|
|1-3 months||Around 15 hours, with the amount slept during the day in a few naps (5-6 hours) decreasing as their night-time sleep increases|
|6-9 months||Around 14 hours, mostly at night as they need less naps|
|1 year||Around 11.5 hours at night with a short nap or two during the day|
Newborns have small stomachs and don’t have a 24-hour body clock (Circadian rhythm) so they can’t tell the difference between night and day. This means you will need to feed them through the night. Many babies sleep through the night without a feed by 6 months but some need an overnight feed until they are nearer 10 months old.
Babies have a similar sleep cycle to adults. The main difference is that babies and young children have shorter sleep cycles. A baby’s sleep cycle lasts 30-40 minutes, a toddler’s about 60 minutes while an adult’s sleep cycle lasts around 90 minutes.
Each sleep cycle consists of two main stages. These are repeated for as long as you or your baby sleeps.
Your baby may wake up briefly during the night after their first sleep cycle. Some babies will settle themselves back to sleep. Others will wake up and cry and need help settling back to sleep.
During the day you may be able to rock your baby back to sleep if they stir after 30-40 minutes of being asleep. If they don’t settle within a few minutes though, they may be ready to wake up.
Babies that sleep near their mothers tend to breastfeed successfully and are nearby for safety. For these reasons it is recommended that babies sleep in your bedroom in their own cots for the first 6 to 12 months. Don’t have the baby in bed with you. This has been linked to an increased risk of sudden infant death syndrome (SIDS) and can lead to unfortunate sleeping accidents.
Night-time sleeping patterns are learned behaviours. By establishing a bedtime routine, your baby will associate this routine with sleep. For example, give your baby a bath, then a feed, have some quiet time together and then put them to bed. Try to pick a routine that you feel comfortable to carry on when they are older. You can start to follow a set nightly sleep routine from as early as three months.
However, it can become a problem if your baby relies on these bedtime cues to go to sleep as they’re not learning to sleep independently. An example is when your baby can’t get to sleep without the habitual cuddle. Another example is a baby who sleeps with a dummy but won’t go back to sleep when it falls out unless you replace it.
If this behaviour develops with your baby, decide on a new pre-bedtime routine and stick to it. Your baby should adapt to the new routine and learn to settle themselves to sleep. This usually takes between 3 and 14 days. Usually 60–70 percent of babies can self-soothe themselves back to sleep without a parent’s help by 8 months of age.
Try to schedule naps at the same times each day. Make sure your baby has enough sleep during the day. Overtired babies are often harder to settle at night. Get to know the signs that they’re getting tired. These can include:
Put your baby to bed while they’re still awake and calm. This helps them learn to sleep independently. A baby who falls asleep in your arms and then wakes up in a cot may be unable to go back to sleep. To relax your baby, try rocking the crib, patting them with a cupped hand or singing to them.
Check for things that may distract your baby from sleeping due to discomfort. Check for wet or dirty nappies, that they are not hungry, overheated or too cold, or that their clothes are not too tight.
It may take 10 minutes or more for your baby to fall asleep. They may grizzle during this time, but you don’t have to go in and soothe them. Usually, as long as your baby isn’t crying, it’s fine to leave the room and let them settle. If they’re crying, you may decide to stay in the room until they're calm and then leave.
‘Controlled comforting’ and ‘camping out’ are two behavioural strategies that are effective in 80 percent of babies or young children who cry and won’t sleep independently. However, before you try either of these approaches make sure your baby is getting lots of attention, time and affection during the day.
Both these approaches can be included as part of the bedtime routine.
The following steps can help reduce the risk of Sudden Infant Death Syndrome (SIDS).
Don’t hesitate to get help if nothing seems to stop your baby crying, or you would like to try the approaches mentioned above.
