Take a look at the following age-by-age chart to help you understand what you can expect regarding babies' sleep-wake cycle, but remembers that your baby may differ from the average.

0-1 Months: Sleep When You Can

Average hours of sleep: 16-18 hours

What to expect: During the first month, all babies need a lot of sleep but sleep patterns vary greatly. At this point, you can’t do much to adjust your baby’s natural tendencies. Just do what you can to help baby get 2-4 hours of sleep between feedings to ensure that both breastfeeding and sleep go more smoothly.

1-3 Months: Starting to Build a Routine

Average hours of sleep: 15-17 hours

What to expect: At around 6 weeks, a more sensible schedule becomes apparent and a bedtime routine may be introduced. Consistency is the name of the game, so make sure you stick to a set routine. You may not see the results immediately but the habit will create the basis for a healthy sleep routine later on.

3-6 Months: Sleeping Through the Night

Average hours of sleep: 14-16 hours

  • 1-1.5 hour morning nap
  • 2 hour midday nap
  • 0.5 hour afternoon nap
  • 10-12 hours at night

What to expect: At this stage, nighttime is supposed to become a time for sleep. Having said that, some babies still wake frequently. Sleep coachers would advise that you seek assistance if your baby still isn’t sleeping between 8-12 hours straight by the time he or she is 6-months-old.

6-9 Months: The Importance of Baby's Surroundings

Average hours of sleep: 14-16 hours

  • 1-1.5 hour morning nap
  • 2 hour midday nap
  • 0.5 hour afternoon nap
  • 10-12 hours at night

What to expect: The number of hours a baby requires at this stage doesn’t alter much, but the pattern of sleep will seem more consistent. Babies at this age may be less flexible about where they sleep and demand the familiar surroundings of their bedroom.

9-12 Months: Growing-Up and Sleeping Less

Average hours of sleep: 12-14 hours

  • 0.5-1 hour morning nap
  • 1.5-2 hour midday nap
  • 10-12 hours at night

What to expect: As the one year brink approaches, baby’s schedule becomes an inseparable part of your life. Many babies will give up their third daytime nap at this stage, going straight for their nighttime slumber. Initially, you will need to make bedtime a little earlier to make sure baby isn’t overtired.

12-18 Months: Down to One Daytime Nap

Average hours of sleep: 12-14 hours

  • 1.5-2 hour midday nap
  • 10-12 hours at night

What to expect: Your baby is slowly turning into a little toddler with a distinct personality and all-too-clear wants and needs. At this point, many babies will settle for only one daytime nap. With time, you’ll be able to delay the nap from the late morning to midday.

Baby's Sleep: Tips

Average hours of sleep: 12-14 hours

  • The best way to determine if your baby is getting enough sleep is to assess the waking hours: if babies are relatively calm, alert and easy-going, then they are probably getting enough sleep. If they are nervous and frequently rub their eyes, they are probably not getting enough sleep. 
  • As your baby grows it becomes increasingly important to stick to a clear schedule that will ensure a healthy sleep routine throughout early childhood.
