At 3 to 4 months, babies begin to settle into a sleep and wake routine.
How much sleep your baby needs
At 3 to 6 months, your baby needs between 12 and 14 hours' sleep. This is across the day and night.
During the day they will usually nap for about 3 to 4 hours. Try to have about 2 hours between naps.
Your baby will sleep for longer at night. But it is normal for them to wake for a short time during the night. Breastfed babies often sleep for short periods between feeds.
Feeds and sleep
At this stage, your baby may still go straight to sleep after a feed. They'll wake for a while before the next feed is due. By about 6 months your baby will stay awake for longer and be more alert between feeds.
Waking during the night
If your baby wakes up during the night, speak to them with a calm, quiet voice. They may drift back to sleep or cry.
How to settle your baby back to sleep:
soothe them if they are crying by speaking softly and holding them
feed them if they are hungry
use a yellow or red dim light rather than a bright or blue light
place your baby back into the cot while they are drowsy but awake
do not talk loudly or play with them
do not turn on your mobile phone or any other screen, as the bright light might wake them more
do not change your baby’s nappy during sleep time unless it is dirty
Ways to build a good sleep routine
Your baby may start to notice the difference between day and night. A bedtime routine can help show your baby that it's getting near sleep time.
Go outdoors each morning
Bring your baby outdoors early in the day. This helps them make the hormone melatonin, which is good for sleep.
Have a 'wind down' every evening
Have a wind down for an hour before bed. Dim the lights and speak softly. Do some relaxing activities, such as bathing your baby.
Change them into night clothes
Feed your baby after you change them into night clothes. Wait for about half an hour before putting them to bed.
No screens before bedtime
During wind down, keep your baby away from bright screens such as your mobile phone or TV. These can make it harder for them to get to sleep.
Keep to the routine
Part of having a good sleep routine is sticking to it.
- put your baby to sleep in the same place when at home
- put them into the cot while awake so they wake where they fell asleep
- avoid feeding or rocking them to sleep
