Baby sleep is one of the biggest concerns for new parents. Night wakings, irregular naps, difficult bedtimes… every baby develops at their own pace. During the first months, it is completely normal for sleep patterns to change frequently. To help you better understand your baby’s needs and feel reassured, here is a complete guide to baby sleep according to age.
Baby Sleep Chart by Age
| Baby’s Age | Average Sleep Time | Key Characteristics |
| 0 to 3 months | 14 to 17 hours | Frequent day and night wakings |
| 4 to 6 months | 12 to 15 hours | Gradual development of day/night rhythm |
| 6 to 12 months | 11 to 14 hours | More regular naps |
| 1 to 2 years | 11 to 13 hours | Transition to one nap |
These sleep durations are only general guidelines: every baby has their own sleep rhythm.
Newborn Sleep: 0 to 3 Months
During the first weeks, a newborn’s sleep is still immature. Babies alternate between wake and sleep phases without clearly distinguishing day from night.
Frequent wakings are completely normal, especially for:
- feeding;
- seeking comfort;
- reconnecting with parents.
At this age, some babies sleep a lot, while others sleep less. There is no need to compare your baby to other newborns.
How Can You Help a Newborn Find a Rhythm?
A few simple habits can gradually help your baby differentiate between day and night:
- exposing your baby to natural daylight during the day;
- keeping a calm atmosphere in the evening;
- creating a soothing bedtime routine.
Sleep rhythms generally develop progressively over the first months.
Baby Sleep Between 4 and 6 Months
Around 4 to 6 months, sleep often starts becoming more regular. Nighttime sleep stretches gradually become longer.
This is also a period when some babies begin to:
- reduce night wakings;
- have more predictable naps;
- fall asleep more easily.
However, this period can also involve changes such as:
- teething;
- motor development;
- a stronger need for reassurance.
Every baby develops differently.
At What Age Does a Baby Sleep Through the Night?
This is probably the most common question asked by new parents.
In reality, there is no exact age when all babies “sleep through the night.” Some babies sleep for several hours in a row very early, while others continue waking for longer.
Night wakings remain very common during the first year and do not necessarily mean there is a problem.
If your baby is not sleeping through the night yet, rest assured: this is completely normal.
Baby Sleep Between 6 and 12 Months
Between 6 and 12 months, sleep usually becomes more structured:
- naps become more organized;
- sleep cycles mature;
- bedtime habits become increasingly important.
However, this period can also include what are often called “sleep regressions.”
Babies Sleep Regressions
Sometimes, a baby who was sleeping well may suddenly:
- wake more frequently;
- struggle to fall asleep;
- need more parental presence.
These phases may be linked to:
- motor development milestones;
- separation anxiety;
- changes in routine.
They are usually temporary.
Naps According to Age
Nap needs evolve significantly during the first years.
In general:
- newborns sleep in short periods throughout the day;
- around 6 months, babies often take 2 to 3 naps;
- around 18 months, many children transition to one nap.
Again, every child has their own rhythm.
How Can You Help Your Baby Fall Asleep?
There is no universal method, but certain habits can help create a reassuring sleep environment:
- establishing a bedtime routine;
- maintaining relatively regular schedules;
- creating a calm atmosphere in the evening;
- limiting stimulation before bedtime.
Most importantly, it is about finding a balance that works for your baby… and your family.
And What About Parents?
Baby sleep can be exhausting for new parents, especially during the postpartum period. Broken nights are part of the early stages of parenthood.
During this intense period, it is important to think about your own comfort too:
- soft and comfortable clothing;
- resting whenever possible;
- creating a cozy, reassuring environment.
Taking care of yourself also helps you better navigate this major life transition.
