The short answer
Night waking can happen at four to six months without establishing a sleep disorder. A baby may wake between sleep periods, need milk, a diaper change, or comfort, or be unwell. Consider feeding, growth, total sleep, and alertness rather than assuming every waking is hunger or a “regression.”

Keep in mind
- Waking alone does not diagnose a sleep disorder.
- Check needs and symptoms rather than using age to end night feeds.
- Keep night care calm and responsive.
- Exhaustion does not change safer-sleep requirements.
Can night waking still happen?
Yes. Brief waking can occur at this age, and some babies settle again while others need care.
AAP describes waking and returning to sleep as possible at six months; uninterrupted nights are not a requirement for every baby.
Why might a change be noticed around four months?
AAP describes sleep cycles becoming more regular around four months.
Families may notice changes as sleep develops, but this does not prove that a developmental change explains every waking.
Does every waking mean hunger?
No. Feeding needs, a wet or dirty diaper, discomfort, surroundings, and a need for reassurance can all matter.
Night feeding depends on growth, milk intake, health, and any individual plan. Do not withhold a needed feed to follow an age-based sleep rule.
Can the room affect sleep?
Heat, bright light, noise, or uncomfortable clothing may disturb settling.
Avoid overheating and keep the sleep surface safe rather than adding soft bedding, pillows, or positioners for comfort.
What about illness or pain?
Fever, congestion, pain, and illness can make sleep more unsettled.
A new pattern with reduced feeding or altered alertness needs attention rather than being labelled only a sleep regression.
Must a baby settle independently?
Babies differ in how they settle and in the help they need.
AAP suggests drowsy-but-awake placement from four months as one approach, not a requirement to withhold feeding or comfort from a distressed or unwell baby.
How can you respond at night?
Use low light, a quiet voice, and minimal stimulation when feeding or changing your baby.
Feed, change, or comfort as needed. Check for illness and make the interaction calm rather than turning it into an active play period.
Does exhaustion change safer sleep?
Place your baby on their back on a firm, flat, non-inclined approved infant sleep surface with only a fitted sheet; keep soft items and loose bedding out. Use a separate sleep space in your room for at least the first six months.
Avoid falling asleep with your baby on a sofa, armchair, or adult bed. Return them to their own sleep space after a feed, and plan for fatigue rather than relying on staying awake.
What can you note today?
If your baby seems well, record waking, feeds, naps, and anything that seems to affect settling.
Seek prompt advice for reduced feeding, fewer wet diapers, fever, or a change in wellbeing. Call 911 for inability to wake, stopped breathing, severe breathing difficulty, or blue/gray color.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Stopped breathing, severe breathing difficulty, blue/gray color, or inability to wake: call 911.
- Reduced feeding, fewer wet diapers, fever, poor weight gain, or an unwell baby needs prompt medical advice.
- Repeated breathing pauses or persistent concern about sleep and wellbeing needs assessment.
