If your baby is 3 months old, you may be wondering if sleeping through the night is finally possible.

And for some babies, it may be.

But sleeping through the night is not just about age. It is also about what is happening during the day: full feeds, age-appropriate wake windows, naps, bedtime, and whether your baby still needs the dreamfeed.

For the purpose of this blog, a “3 month old” means a baby around 13–17 weeks old, or 3–4 months old.

At this age, sleep can begin to feel more organized. Wake windows are getting longer, many babies are ready for around 4 naps, bedtime may feel more consistent, and some babies are beginning to sleep longer stretches overnight.

But if your baby is still waking at night, you are not doing anything wrong.

At 3 months old, better sleep usually starts during the day. Full feeds, age-appropriate wake windows, naps, bedtime, and the dreamfeed all work together to support longer stretches of sleep when your baby is ready.

So let’s walk through what sleep can look like at 3 months old, how many naps your baby may need, what wake windows to aim for, and how feeding continues to impact sleeping through the night.

The Short Answer: Most babies this age do best with a flexible routine that includes full daytime feeds, wake windows around 60–90 minutes, about 4 naps, a consistent bedtime, and a dreamfeed between 10–11pm if you are still using one. Some babies may begin working toward dropping the dreamfeed between 12–16 weeks if they are consistently sleeping through the night, but there is no need to rush it.

Some 3 month olds can begin sleeping through the night, while others may still need a feed. If your baby is not getting enough milk during the day, they may continue waking overnight because they still need those calories.

The goal is not to force sleep. The goal is to make sure your baby’s daytime routine is supporting nighttime sleep.

3 Month Old Sleep Guidelines

Every baby is different, but these general guidelines can help you know what to expect around 13–17 weeks old.

Wake Windows = About 60–90 minutes
Daytime Feeds = Often every 2.5–3.5 hours with full feedings®
Number of Naps = Usually around 4 naps
Nap Length = Guided by feeding needs and total daytime sleep
Bedtime = Around 7pm
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 Feeding Still Impacts Sleep at 3 Months Old

At 3 months old, many parents start focusing more on naps, wake windows, and bedtime.

And yes — those matter.

But feeding still matters too.

If your baby is not getting full feeds during the day, they may wake overnight because they still need those calories. If your baby recently dropped a nap or a daytime feed, you may also notice new night waking or early morning waking.

This is why I always want you to look at sleep and feeding together.

A 3 month old who is waking overnight may not have a “sleep problem.” They may have a daytime fullness problem, a nap transition problem, or a routine that simply needs adjusting.

Full feedings® help your baby get more of their calories during the day, which can support longer stretches at night when they are developmentally ready.

This does not mean force feeding. It does not mean ignoring hunger. And it does not mean your baby must be sleeping through the night by now.

It means daytime feeds are one of the first places to look when nighttime sleep feels disrupted.

How Long Should a 3 Month Old Be Awake?

Most 3 month olds do best with wake windows around 60–90 minutes.

Some babies will need the shorter end of that range, especially earlier in the month. Others may gradually work toward the longer end as they approach 4 months old.

A wake window includes everything that happens while your baby is awake:

✔️ feeding
✔️ burping
✔️ diaper change
✔️ playtime
✔️ wind-down
✔️ getting ready for sleep

This is important because many parents assume wake time means “playtime after feeding,” but feeding counts as awake time.

If your baby wakes, takes a full feed, burps, gets changed, and has a few minutes of interaction, they may already be getting close to needing sleep again.

If your baby is fighting naps, waking shortly after being put down, or melting down before bedtime, the wake window may be too long.

If your baby takes a long time to fall asleep or seems wide awake when you offer the nap, the wake window may be too short.

How Many Naps Should a 3 Month Old Take?

Most 3 month olds are taking around 4 naps per day.

This is one of the big changes from the earlier newborn months. Your baby may be moving away from needing that extra 5th nap, and their daytime sleep may start to feel more predictable.

That transition can be tricky.

When a baby drops a nap, they may also lose a daytime feeding opportunity. If that happens too quickly, some babies begin waking more at night because they are not getting enough daytime calories.

So if your baby recently moved from 5 naps to 4 naps and sleep suddenly feels harder, look at feeding first.

Ask yourself:

Are daytime feeds still full?
Did baby drop a feed when they dropped the nap?
Is baby waking earlier in the morning?
Is baby waking overnight after previously sleeping longer?
Is bedtime too late because the last wake window got too long?

A nap transition is not just a sleep transition. It can also be a feeding transition.

What Should a 3 Month Old Routine Look Like?

At 3 months old, your baby’s routine can become more predictable, but it still does not need to be rigid.

Instead of exact clock times, think about the rhythm of the day:

Wake → full feeding → awake time → nap → repeat

At this age, your baby may have a little more awake time after feeding, but they still need sleep before becoming overtired.

The goal is not to follow a perfect schedule. The goal is to create a flow where your baby has regular opportunities for full feeds, age-appropriate naps, and a bedtime that supports nighttime sleep.

If the day feels off, look at these three things first:

Are feeds staying full? If feeds get smaller during the day, night waking can increase.
Are wake windows age-appropriate? Too much awake time can lead to overtiredness, short naps, false starts, and more night waking.
Is daytime sleep supporting nighttime sleep? Too little daytime sleep can cause overtiredness, but too much daytime sleep can make nights harder.

What Time Should a 3 Month Old Go to Bed?

Many 3 month olds do well with bedtime around 7:00pm.

This does not mean every night will look perfect. Some days, bedtime may need to shift earlier if naps were short. Other days, bedtime may land slightly later depending on how the day unfolded.

A simple bedtime routine can help your baby begin to understand that nighttime sleep is coming.

Your routine may include:

✔️ diaper change
✔️ feeding
✔️ burping
✔️ sleep sack or swaddle transition, if appropriate
✔️ sound machine
✔️ dark room
✔️ down for sleep

At this age, bedtime consistency can be very helpful, but consistency does not mean rigidity.

Can a 3 Month Old Sleep Through the Night?

Some 3 month olds can begin sleeping through the night, while others still need a night feed.

This depends on your baby’s size, intake, feeding ability, daytime calories, growth, and pediatrician guidance.

If your baby is still waking to eat overnight, the first question is not, “How do I stop this immediately?”

The first question is: Is my baby getting enough full feeds during the day?

If the answer is no, focus there first.

Night feeds often improve naturally when daytime feeds are full, wake windows are appropriate, naps are not interfering with feeding, and bedtime is well-timed.

Always feed your baby if you believe they are hungry.

Does a 3 Month Old Still Need Night Feeds?

Some 3 month olds still need night feeds, and some are beginning to sleep longer stretches.

Both can be normal.

If your baby is waking overnight and taking a full feed, they may still need those calories. If your baby is waking overnight but not taking a full feed, it may be worth looking at the whole day to see whether feeding, naps, wake windows, or bedtime need to be adjusted.

The goal is not to withhold food from a hungry baby.

The goal is to support more daytime calories, full feeds, and healthy sleep rhythms so your baby can begin stretching longer when they are developmentally ready.

Can a 3 Month Old Drop the Dreamfeed?

Some babies may be ready to begin working toward dropping the dreamfeed between 12–16 weeks old, especially if they have been consistently sleeping through the night.

But not every baby is ready, and there is no need to drop the dreamfeed just because your baby is 3 months old.

If the dreamfeed is still helping your baby get enough calories and sleep longer overnight, it can still be useful. It may also be helpful if your baby is exclusively breastfed, not taking enough during the day, or still waking overnight hungry.

Before dropping the dreamfeed, ask:

Is baby sleeping through the night consistently?
Are daytime feeds full?
Is baby taking enough milk during the day?
Has night sleep been stable for at least a couple of weeks?
Does baby wake hungry when the dreamfeed is skipped?

If dropping the dreamfeed causes new night waking or early morning waking, your baby may not have been ready yet.

I would not put a big dreamfeed explanation in the intro. Just lightly mention it there, then save the real teaching for the dreamfeed section.

What If My 3 Month Old Suddenly Starts Waking at Night Again?

If your 3 month old was sleeping well and suddenly starts waking again, do not panic.

This can happen for several reasons:

✔️ a nap transition
✔️ not enough daytime milk
✔️ too much daytime sleep
✔️ too little daytime sleep
✔️ wake windows that need adjusting
✔️ growth or development
✔️ bedtime timing
✔️ the dreamfeed being dropped too soon

At this age, I would look at daytime feeding first.

If your baby recently dropped from 5 naps to 4 naps, they may have also dropped a feeding opportunity. If that causes a decrease in daytime intake, nighttime sleep may be disrupted.

That does not mean you did anything wrong. It simply means your baby may need a little more support as the day changes.

What If My 3 Month Old Is Taking Short Naps?

Short naps can still be common at 3 months old.

But if every nap is short, it is worth looking at the full picture.

Ask yourself:

Was the wake window too long?
Was the wake window too short?
Did baby get a full feed before the nap?
Is baby waking hungry?
Is baby overtired by the end of the day?
Is the last nap too late or too long?

Short naps are not always a feeding issue, but feeding is always worth considering.

If your baby wakes from a short nap and is immediately hungry, or if they are snacking all day because naps are short, you may need to adjust the rhythm of the day so feeds can stay full.

What If My 3 Month Old Is Waking Early?

Early morning wakes can be frustrating, especially if your baby was previously sleeping later.

At 3 months old, early wakes can happen when:

✔️ baby is hungry
✔️ daytime feeds are not full
✔️ bedtime is too late
✔️ baby is overtired
✔️ daytime sleep is too much or too little
✔️ the dreamfeed was dropped too soon
✔️ the first feed of the day is happening too early without a full wake window

If your baby wakes early and seems truly hungry, feed them. But if early waking becomes a pattern, look at the full day: feeds, naps, wake windows, bedtime, and the dreamfeed.

What If My 3 Month Old Still Needs Contact Naps?

Contact naps can still happen at 3 months old.

You can enjoy them when they work for your family, and you can also begin practicing crib or bassinet naps if that is your goal.

The key is not forcing independent naps all day long. The key is making sure your baby is getting the daytime sleep they need while still protecting feeds and bedtime.

If every nap is a battle, start with one nap per day where you practice laying baby down in their sleep space.

Keep the focus on consistency, not perfection.

Common 3 Month Old Sleep Struggles

My 3 month old is fighting naps

This may mean the wake window is too short, too long, or baby is overtired. It can also happen during nap transitions. Look at the full day before changing everything at once.

My 3 month old wakes 30–45 minutes into naps

This can be developmental, but it may also be related to hunger, wake windows, or over tiredness. If baby wakes hungry, look at daytime feeds.

My 3 month old started waking overnight again

Look at daytime intake first. If baby dropped a nap or feed, they may need more calories during the day.

My 3 month old wakes early in the morning

Early wakes can be related to hunger, overtiredness, too much daytime sleep, bedtime timing, or dropping the dreamfeed too soon.

My 3 month old still needs the dreamfeed

That can be normal. If the dreamfeed helps your baby sleep longer and supports daytime/evening intake, it may still be a useful tool.

Frequently Asked Questions

Final Thoughts

At 3 months old, sleep can start to feel more predictable, but there are still a lot of moving pieces.

Wake windows matter. Naps matter. Bedtime matters. But feeding still plays a major role.

If your baby’s sleep suddenly feels harder, look at the full picture before assuming something is wrong. Full daytime feeds, age-appropriate wake windows, the right number of naps, bedtime, and the dreamfeed all work together.

And when those pieces are aligned, your baby is in a much better position to sleep longer stretches when they are ready.
