5 Month Old Sleep Schedule: Wake Windows, Short Naps & Night Sleep
If your baby is 5 months old, you may feel like sleep is changing all over again.
Maybe naps suddenly got shorter.
Maybe your baby is fighting the fourth nap.
Maybe bedtime has become harder.
Maybe your baby was sleeping well and suddenly started waking overnight again.
Or maybe you’re wondering if it’s time to drop to 3 naps.
For the purpose of this blog, a “5 month old” means a baby around 21.5–26 weeks old, or 5–6 months old.
At this age, sleep is changing, but feeding still matters.
Wake windows are increasing. Daytime sleep needs are gradually decreasing. Many babies begin the transition from 4 naps to 3 naps. Some babies start solids. And many parents notice that short naps suddenly become more common.
But before you assume every sleep change is a regression, it’s important to look at the full picture.
Wake windows, naps, bedtime, full feedings®, daytime milk intake, solids, and the dreamfeed can all impact nighttime sleep.
So let’s walk through what sleep can look like at 5 months old, how many naps your baby may need, what wake windows to aim for, why short naps happen, and how feeding still impacts sleep.
The Short Answer: A good 5 month old sleep schedule is not a rigid clock-based schedule.
Most babies this age do best with a flexible routine that includes full daytime feeds, wake windows around 80–100 minutes, about 4 naps, a consistent bedtime around 6:30–7:00pm, and a dreamfeed if your baby still benefits from one.
Many babies begin working toward a 3-nap schedule by the end of this month, but there is no need to rush the transition.
The goal is not to force your baby into fewer naps.
The goal is to make sure feeding, naps, wake windows, and bedtime are all supporting nighttime sleep.
5 Month Old Sleep Guidelines
Wake Windows = About 80–100 minutes
Daytime Feeds = Often every 3 hours with full feedings®
Number of Naps = Usually around 4 naps
Nap Length = Often shorter this month as sleep needs begin to change
Bedtime = Around 6:30–7:00pm
Dreamfeed = Between 10–11pm if using one
Night Feedings = Some babies still need them; focus on full daytime feeds
Please remember: these are general guidelines. Your baby’s weight gain, feeding method, intake, medical history, and pediatrician’s guidance all matter.

Why Sleep Can Change at 5 Months Old
Five months is a major transition month.
Your baby’s sleep needs are beginning to change.
Wake windows get longer.
Daytime sleep slowly decreases.
The final wake window begins stretching.
Many babies begin showing signs that they are eventually working toward dropping their fourth nap.
At the same time, babies are becoming more aware of the world around them. Rolling, reaching, exploring, and developmental milestones can all impact sleep.
Because so much is happening, parents often assume every sleep disruption is a regression.
But that’s not always the case.
Sometimes sleep changes because wake windows need adjusting.
Sometimes daytime sleep is becoming excessive.
Sometimes naps need to be shortened.
Sometimes solids are affecting milk intake.
And sometimes your baby simply isn’t getting enough daytime calories.
This is why feeding and sleep should always be looked at together.
Why Feeding Still Impacts Sleep at 5 Months Old
At 5 months old, feeding is still a major piece of nighttime sleep.
In fact, many sleep disruptions that appear to be sleep problems are actually feeding problems.
If your baby recently started:
✔️ taking shorter feeds
✔️ becoming distracted while feeding
✔️ drinking less milk after starting solids
✔️ snacking instead of taking full feeds
✔️ waking more frequently overnight
it is worth looking at daytime intake first.
If your baby isn’t getting enough calories during the day, they may continue waking overnight because they still need those calories.
A 5 month old who suddenly starts waking overnight may not have a sleep problem.
They may have a feeding problem.
They may have a wake window problem.
They may have a daytime sleep problem.
Or they may simply need the day adjusted so feeding and sleep can work together again.
full feedings® help your baby get more calories during the day, which supports longer stretches of sleep when your baby is developmentally ready.
This does not mean forcing your baby to eat.
It does not mean ignoring hunger cues.
It means protecting full daytime feeds so your baby is not relying on overnight calories they could have taken during the day.
Feeling unsure whether your baby’s night waking is hunger,
habit, overtiredness, too much daytime sleep,
or a schedule issue?
The Full Feedings Infant Sleep Program walks you through how to
use full feedings®, wake windows, naps, bedtime, dreamfeeds,
and responsive overnight support without cry-it-out.
How Long Should a 5 Month Old Be Awake?
Most 5 month olds do best with wake windows around 80–100 minutes.
Many babies start the month closer to 80 minutes and gradually work toward longer wake windows as they approach 6 months old.
A wake window includes everything your baby does while awake:
➕ feeding
➕ burping
➕ diaper changes
➕ playtime
➕ tummy time
➕ getting ready for sleep
Feeding still counts as part of the wake window.
If your baby is fighting naps, becoming fussy before sleep, having false starts at bedtime, or waking shortly after being put down, the wake window may be too long.
If your baby takes a long time to fall asleep or seems wide awake when offered a nap, the wake window may be too short.
How Many Naps Should a 5 Month Old Take?
Most 5 month olds still do best with around 4 naps per day.
One of the biggest mistakes I see at this age is dropping the fourth nap too early.
Parents often assume that because sleep is becoming more difficult, the solution is fewer naps.
But in many cases, keeping the fourth nap a little longer actually helps protect bedtime and nighttime sleep.
The goal this month is usually not to rush the transition to 3 naps.
The goal is to hold onto the fourth nap for as long as your baby still needs it.
Many babies won’t be ready to fully transition to 3 naps until closer to 6 months old.
Why Are My 5 Month Old’s Naps Suddenly Short?
Short naps become incredibly common at this age.
And surprisingly, they are not always a problem.
As babies move toward the 4-to-3 nap transition, shorter naps can sometimes help preserve the fourth nap and keep bedtime from becoming too early.
Not every short nap needs fixing.
Instead of focusing on a single nap, look at the entire day.
Ask yourself:
Was the wake window appropriate?
Did baby get a full feed before the nap?
Is baby overtired by bedtime?
Is total daytime sleep still appropriate?
Are nighttime sleep and mood generally improving?
A short nap is only one piece of the puzzle.
What Time Should a 5 Month Old Go To Bed?
Many 5 month olds do well with bedtime around 6:30–7:00pm.
As the month progresses, bedtime may shift slightly depending on naps and wake windows.
If your baby refuses the fourth nap, an earlier bedtime is often better than trying to push through overtiredness.
A simple bedtime routine may include:
✔️ feeding
✔️ diaper change
✔️ sleep sack
✔️ sound machine
✔️ dark room
✔️ bedtime
Consistency helps, but flexibility still matters.
Should My 5 Month Old Drop to 3 Naps?
Maybe.
But probably not yet.
Most babies benefit from holding onto 4 naps until closer to 6 months old.
If your baby begins fighting the fourth nap, having bedtime struggles, or showing signs that daytime sleep is becoming excessive, adjustments may be needed.
But I would look at total daytime sleep and wake windows before immediately dropping a nap.
Remember: The goal is not fewer naps. The goal is better sleep.
Can Starting Solids Affect Sleep?
Yes.
One of the biggest misconceptions I hear is that starting solids automatically improves sleep.
Sometimes the opposite happens.
When babies begin solids, they often take less milk.
And when milk intake decreases, sleep can become worse.
Milk should remain your baby’s primary source of nutrition throughout this stage.
If you’ve recently started solids and your baby suddenly has:
✔️ new night wakings
✔️ early morning wakes
✔️ shorter stretches of sleep
✔️ reduced daytime intake
it may be worth looking at milk intake first.
Offer milk before solids and continue prioritizing full feedings® throughout the day.
Common 5 Month Old Sleep Struggles
My 5 Month Old Takes Short Naps
Short naps are common at this age. Look at the full day before assuming every nap needs fixing.
My 5 Month Old Is Fighting the Fourth Nap
This can be a sign that sleep needs are changing, but many babies still benefit from keeping the fourth nap a little longer.
My 5 Month Old Started Waking Overnight Again
Look at daytime feeding first. Reduced milk intake often shows up as night waking.
My 5 Month Old Wakes Early
Early morning wakes can be related to hunger, overtiredness, bedtime timing, daytime sleep, or reduced milk intake.
My 5 Month Old Started Solids and Sleep Got Worse
This often happens when solids begin replacing milk instead of complementing milk.
Frequently Asked Questions
What is a good sleep schedule for a 5 month old?
A good 5 month old sleep schedule includes full daytime feeds, wake windows around 80–100 minutes, about 4 naps, and a bedtime around 6:30–7:00pm.
Most babies this age are not ready for a rigid clock-based schedule. Instead, focus on a flexible routine that supports full feedings®, age-appropriate wake windows, naps, and bedtime. Many babies begin working toward a 3-nap schedule closer to 6 months old.
How long should a 5 month old stay awake?
Most 5 month olds do best with wake windows around 80–100 minutes.
Some babies start the month closer to 80 minutes and gradually work toward longer wake windows as they approach 6 months old. Feeding, diaper changes, playtime, and getting ready for sleep all count as part of the wake window.
How many naps should a 5 month old take?
Most 5 month olds still need about 4 naps per day.
Although some babies begin showing signs they are working toward a 3-nap schedule, many benefit from keeping the fourth nap until closer to 6 months old. Dropping naps too early can sometimes lead to overtiredness and increased night waking.
When should a 5 month old drop to 3 naps?
Most babies are not ready to consistently drop to 3 naps until closer to 6 months old.
If your baby is fighting the fourth nap, bedtime is becoming difficult, or daytime sleep is becoming excessive, they may be starting the transition. However, many babies still benefit from keeping 4 naps as long as possible.
Why is my 5 month old taking short naps?
Short naps are very common at 5 months old.
Sleep needs are changing, wake windows are increasing, and many babies are beginning the transition from 4 naps to 3 naps. Before trying to fix every short nap, look at the full picture, including wake windows, daytime feeding, bedtime, and total daytime sleep.
Can solids affect sleep at 5 months?
Yes, solids can affect sleep if they cause your baby to drink less milk.
Milk should remain your baby’s primary source of nutrition at this age. If milk intake decreases after introducing solids, some babies may experience new night waking, early morning wakes, or shorter stretches of sleep.
Does feeding impact sleep at 5 months?
Yes, feeding still plays a major role in sleep at 5 months old.
If your baby is not getting enough calories during the day, they may continue waking overnight because they still need those calories. Full daytime feeds can help support longer stretches of sleep when your baby is developmentally ready.
What time should a 5 month old go to bed?
Many 5 month olds do well with a bedtime between 6:30pm and 7:00pm.
Bedtime may occasionally need to be adjusted based on naps and wake windows. If your baby skips the fourth nap, an earlier bedtime is often better than allowing them to become overtired.
Why is my 5 month old suddenly waking up at night again?
A 5 month old may start waking overnight again because of reduced daytime milk intake, changing sleep needs, overtiredness, daytime sleep issues, developmental milestones, or the introduction of solids.
Before assuming it is a sleep regression, look at the full day. Full feeds, age-appropriate wake windows, naps, and bedtime timing all play a role in nighttime sleep.
Is there a 5 month sleep regression?
There is no official 5 month sleep regression, but many babies experience sleep disruptions around this age.
Sleep may change because wake windows are increasing, daytime sleep needs are decreasing, developmental milestones are emerging, or feeding patterns have changed. Looking at the full picture often provides more helpful answers than simply labeling it a regression.
Can a 5 month old sleep through the night?
Some 5 month olds can sleep through the night, while others still need a night feed or dreamfeed.
Both can be normal. If your baby is still waking to eat overnight, focus on ensuring they are getting full feeds during the day while continuing to respond to hunger appropriately.
Should my 5 month old still have a dreamfeed?
Maybe.
If the dreamfeed is helping your baby get enough calories, sleep longer stretches, or reduce night waking, it can still be a helpful tool. There is no need to rush dropping the dreamfeed simply because your baby is 5 months old.
Why is my 5 month old waking up early?
Early morning waking can happen when a baby is hungry, overtired, getting too much or too little daytime sleep, experiencing bedtime timing issues, or drinking less milk during the day.
If early waking becomes a pattern, look at daytime feeding, wake windows, naps, bedtime, and any recent changes such as starting solids.
