"When will my baby sleep through the night?" Every parent has wondered this at some point. For exhausted parents dealing with night feedings and frequent wakings, this guide explains when babies start sleeping through the night and how to help them get there.

What Does "Sleeping Through the Night" Mean?

For babies, "sleeping through the night" doesn't mean 8-10 hours like adults. It means 6-8 hours of continuous sleep. Even this much can dramatically improve parents' quality of life!

💡 Baby's "sleeping through the night" = 6-8 hours of continuous sleep. Remember this is different from an adult's 8-10 hours!

When Do Babies Sleep Through the Night by Age

Age	Continuous Sleep	Characteristics
0-2 months	2-4 hours	Small stomach, wakes often; no day/night distinction
3-4 months	4-6 hours	Longer night sleep becomes possible
5-6 months	6-8 hours	Many babies start sleeping through
7-9 months	8-10 hours	Most can sleep through the night
10-12 months	10-12 hours	Stable nighttime sleep

Important: Every baby is different. Some sleep through at 3 months, others still wake at 12 months. Both are normal.

Why Newborns Wake Frequently

There are physiological reasons why newborns can't sleep through:

1. Small Stomach Capacity

Newborn stomach size: cherry to egg-sized
Can only hold small amounts, gets hungry often

2. Short Sleep Cycles

Newborn sleep cycle: ~50 minutes (adults: 90 minutes)
Easily wakes between cycles

3. Undeveloped Circadian Rhythm

Body clock develops around 3-4 months
Before that, they don't know night is for sleeping

Basic Principles for Sleeping Through

1. Put Down Drowsy But Awake

Key: Put baby down when drowsy, not fully asleep.

When eyes start closing
When movements slow down
When yawning

This teaches baby to "fall asleep in bed." They can then self-soothe when waking at night.

2. Consistent Bedtime Routine

A consistent routine signals to baby's brain that it's "time to sleep."

Recommended Bedtime Routine (20-30 minutes):

Bath (warm water for relaxation)
Lotion/massage
Change into pajamas
Feeding (outside the bed)
Reading/lullaby
Lay in bed

3. Appropriate Bedtime

Timing bedtime with baby's natural rhythm is crucial.

Age	Recommended Bedtime
3-6 months	7:00-8:00 PM
6-12 months	6:30-7:30 PM
12+ months	7:00-8:00 PM

4. Differentiate Day and Night

During the day:

Bright lights, normal household noise
Active play and interaction
Naps in lit areas

At night:

Dim lights (even for feeding/diaper changes)
Quiet, calm interactions
Minimal stimulation

Age-Specific Strategies

0-3 Months: Building Foundation

Don't expect sleeping through at this stage. Focus on foundations:

Establish eat-play-sleep pattern
Start day/night differentiation
Use white noise
Create safe sleep environment

4-6 Months: Preparing for Sleeping Through

Many babies start sleeping through at this stage:

Gradually reduce night feeds (consult doctor)
Establish bedtime routine
Organize nap schedule
Consider sleep training if needed

7-12 Months: Stabilizing Sleep

Most babies can sleep through:

Wean night feeds completely (if needed)
Handle separation anxiety
Overcome sleep regressions
Consistency is key

How Long Should Night Feeding Continue?

Age	Night Feeds	Notes
0-3 months	2-3 times	Essential, feed on demand
4-6 months	1-2 times	Gradually reducing
6-9 months	0-1 time	Decreases after starting solids
9+ months	0 possible	Nutritionally unnecessary

Note: This varies based on growth, weight, and health. Always consult your pediatrician.

What Prevents Sleeping Through

Sleep Associations

Things baby needs to fall asleep:

Feeding to sleep
Rocking to sleep
Falling asleep with pacifier

These habits mean baby needs parents to fall back asleep when waking at night.

Overtiredness

Paradoxically, overtired babies sleep worse:

Increased cortisol (stress hormone)
Difficulty falling asleep
Frequent waking

Solution: Adequate naps and early bedtime

Hunger or Discomfort

Check basic needs:

Was the last feeding enough?
Is the diaper dry?
Is temperature appropriate? (68-72°F / 20-22°C)
Any signs of illness?

When Baby Wakes at Night

Wait and see (1-2 minutes)

Check if baby can self-soothe
Not every movement means "awake"

Minimal intervention

Don't turn on lights
Don't talk
Only address needs (feeding, diaper)

Stay consistent

Respond the same way each time
Make it predictable for baby

When to Seek Professional Help

Consult your pediatrician if:

Waking 3+ times every night after 6 months
Snoring or sleep apnea symptoms
Excessive daytime lethargy
Slow weight gain
Serious impact on parents' health
