Tips for your 9-month-old's sleep schedule

You tuck your little one into their crib, gently stroking their soft hair. After a full day of crawling, exploring, and maybe even pulling themselves up to stand, they’re ready for some rest. As you tiptoe away, hoping for a peaceful night, you hear a tiny whimper. Another sleep battle? Not exactly!

At 9 months, your baby is more active than ever, and while their sleep might feel unpredictable at times, that’s all part of their growth. One night, they sleep soundly, and the next, they might wake up a bit more. Shorter naps, louder protests, and a touch of separation anxiety? It’s all normal, and you're not alone.

The good news? With a flexible yet comforting routine, you can guide your baby through this phase and find a balance that works for both of you. 

Let’s take a look at a 9-month-old sleep schedule and some practical tips to help everyone get the restful sleep they need.

What to expect

Here is what we will talk about in this article:

How much sleep does a 9-month-old need?

By 9 months, most babies need around 13 to 14 hours of total sleep per day, with 11 to 12 hours at night and 2 to 3 hours across naps. While some babies sleep through the night, others may still experience night wakings.

Changes in sleep patterns are common at this stage. Your baby might:

  • Take two naps per day, usually morning and afternoon.
  • Stay awake for 3 to 4 hours between sleep periods.
  • Wake up briefly at night as they transition between sleep cycles.
  • Experience separation anxiety, making bedtime a bit more challenging.

If sleep feels inconsistent, know that it’s temporary. Small adjustments can help your baby settle into a more predictable routine.

Sleep fact: The National Sleep Foundation1 recommends 12 to 15 hours of total sleep for babies between 4 and 12 months. However, some babies naturally need a little more or less sleep than the average.

A structured sleep schedule can make a big difference, so let’s take a look at what a typical day might look like. 

What does a sample 9-month-old sleep schedule look like?

A consistent routine helps babies know what to expect, making sleep smoother for everyone. 

What are the benefits of a consistent routine?

  • Better sleep pattern: It helps regulate a baby's internal clock, making it easier to fall asleep and reducing nighttime wakings.
  • Emotional security and reduced stress: It provides stability and security, reducing anxiety and meltdowns by giving babies a sense of control.
  • Improved feeding and digestion: Regular mealtimes help regulate hunger cues and digestion, reducing fussiness from unpredictable feeding gaps.
  • Supports cognitive and emotional development: Routines support learning by helping babies recognize patterns, while consistent interactions strengthen bonding and language skills.
  • Easier transition for parents: Predictability helps parents plan the day, anticipate their baby's needs, and prevent overtiredness or overstimulation.

Here’s an example of a 9-month-old sleep schedule that balances naps, wake windows, and bedtime.

Important note: Not every day will follow this schedule exactly, but keeping naps and bedtime around the same time can help regulate your baby’s internal clock. 

Tip: If your baby resists naps or wakes up frequently, adjusting wake windows or bedtime might help. Let’s go through some tips to improve their sleep.

Why is my baby struggling with sleep, and how can I fix it?

Even with a solid sleep schedule in place, sleep can still be unpredictable. Some nights go smoothly, while others feel like a never-ending cycle of rocking, feeding, and waking up again. Guess what? That’s completely normal! The key is to balance structure with flexibility while staying tuned in to your baby’s sleep cues.

Are wake windows too short or too long?

A 9-month-old’s wake windows are usually between 3 to 4 hours between sleep periods. If your baby stays awake for too long, they might become overtired, which leads to more frequent night wakings or short naps.

  • Morning wake window: 2.5 to 3 hours
  • Between naps: 3 to 4 hours
  • Before bedtime: 3.5 to 4 hour

If your baby is resisting sleep, try adjusting these wake windows by 15 to 30 minutes and see if it makes a difference.

Is your bedtime routine helping or hurting sleep?

Consistency is key here. Babies thrive on predictability, and a soothing bedtime routine signals that it’s time to wind down. A calming routine might include:

  • A warm bath or a relaxing massage. 
  • Putting on the baby’s pj’s.
  • A short bedtime story or relaxing lullaby. 
  • Draw the curtains or dim lighting to signal bedtime. 
  • A final feeding session to ensure your baby is full

Repeating these steps nightly helps babies settle down and fall asleep more easily.

Is your baby struggling with separation anxiety?

At 9 months, your baby is beginning to understand object permanence, meaning they know when you leave the room and they don’t like it! This can cause bedtime resistance and lead to more frequent night wake-ups.

To help them adjust:

  • Practice short goodbyes during the day.
  • Introduce a comfort item, like a soft blanket or stuffed toy.
  • If they wake at night, offer gentle comfort without picking them up immediately.

Is your baby taking too many naps?

Daytime sleep plays a significant role in your baby's overall rest, but too much of it can interfere with nighttime sleep. If your baby is struggling to settle at bedtime or waking up more frequently during the night, excessive daytime naps might be the cause. While naps are essential for growth and development, it’s important to strike the right balance.

Here’s why:

  • Nap duration matters: Naps longer than two hours are generally fine as long as they don’t disrupt your baby’s nighttime sleep. It’s important to ensure your baby gets enough active, awake time to be ready for bed at night.

    💡 Tip: If a nap goes over 2.5 hours, gently wake the baby to maintain a balanced sleep schedule. But if they’re sick or going through a growth spurt, extra sleep is totally normal! 😊
  • Adequate daytime calories: Limiting naps to 2 hours or less ensures your baby gets the necessary calories during the day to support good sleep at night.
  • Bedtime timing: Longer naps during the day can push your baby’s bedtime too late, potentially affecting their ability to fall asleep between 7:00 and 8:00 pm. A consistent bedtime is key for better sleep.

A slight adjustment to naps can help improve nighttime sleep without leaving your baby overtired. 

Could your baby be going through the 9-month sleep regression?

If sleep suddenly worsens despite your best efforts, it’s likely that your baby is experiencing sleep regression. This temporary disruption is often caused by factors like separation anxiety, increased mobility (such as pulling to stand or crawling), and changing nap needs. While the regression can cause your baby to resist sleep or wake up more frequently, it’s important to remember that this phase is temporary.

Stick to the routine, offer extra comfort at bedtime, but avoid creating new sleep habits that could become difficult to break. Most regressions last between 2 to 6 weeks, and with a little patience, love and consistency, your baby will adjust.
