Healthy sleep patterns start with a schedule. Here’s how to get your baby onto a regular 15 month old sleep schedule with top tricks to make it as easy as possible.

How Much Should A 15 Month Old Sleep?

Sample 15 Month Old Sleep Schedule

By 15 months old, your little one should be sleeping through the night and having between 1 and 2 naps a day (depending on how busy they have been).

However, if they are going through a nap transition then the morning nap will be dropped and the afternoon nap will become longer.

Here is a sample 15 month old sleep schedule to give you a guideline for how your little one’s day can flow regardless of whether they take 1 or 2 naps:

REMEMBER: This 15 month old sleep schedule is only a guideline and will differ from child to child. The most important thing to focus on is how much sleep your little one requires in 24 hours and work from there.

Nap Schedule For 15 Month Old

You may find that at around 15 months old, your baby may struggle to settle for their morning nap, but will happily take a longer afternoon nap.

This is the beginning of a 15 month old nap transition.

Not every child will go through this yet and most 15 month olds will still require 2 naps a day for the time being.

Here’s a handy quick reference for a 15 month old nap schedule to help you visualise your child’s daytime sleep habits regardless of whether they have 1 or 2 daytime naps:

Nap Schedule For A 15 Month Old Baby

How Long Should A 15 Month Old Nap?

Your 15 month old will require around 2 hours of nap time during the day.

I would not recommend letting your child sleep for longer than 2 hours in the afternoon as this may affect your child’s ability to fall asleep at bedtime.

Is 15 Months Too Early For One Nap?

Some 15 month olds can manage 1 daytime nap but most will still need 2 naps per day to avoid becoming overtired

As this is a nap transition phase, you will need to keep a keen eye on sleep cues and be prepared to be flexible, by adjusting awake windows and the length and number of naps on a daily basis. 

TOP TIP: Always keep in mind how much sleep your little one is getting in a 24 hour period to help you work out how much daytime sleep they need. 

How Many Naps For A 15 Month Old?

Most 15 month olds will need 2 naps a day… A shorter morning nap and a longer afternoon one.

However, this is the beginning of a nap transition phase from 2 naps to 1 and so be prepared for your little one to show signs of not wanting to nap twice a day, every day. 

If your baby does want to drop a nap, you should drop the morning nap first and ensure the afternoon nap is about 2 hours long.

Bedtime For 15 Month Old

As always, a regular and healthy bedtime routine is essential to your baby’s good night’s sleep. And for a 15 month old sleep schedule, your baby’s bedtime routine will consist of:

The entire bedtime routine should start between 6pm and 6.30pm and ideally, take no longer than 30 minutes.

REMEMBER: The bedtime routine should follow the same steps and be repeated at the same time every evening to ensure your 15 month old can recognise the signs that bedtime is coming to help them settle and fall asleep more easily. You can use a bedtime routine chart to help your little one know what’s coming up.

What Time Should A 15 Month Old Go To Bed?

For a 15 month old sleep schedule, your little one should be in bed with the lights out by 7pm.

If you want to adjust your schedule to make bedtime a little later you must change your daily nap times accordingly.

But no matter what… your child should not be in bed any later than 8pm.

TOP TIP: If your little one is continually resisting nap time try lengthening the wake window between naps before considering dropping a nap. Also, remember that during a nap transition your toddler may need to nap twice on some days but only once on others depending on how well they have slept at night and how busy their day has been.

Is 9pm Too Late For Toddler Bedtime?

Yes, 9pm is too late for a 15 month old toddler bedtime. 

The bedtime routine is the cornerstone of healthy sleep and you should aim to have your little one in bed by 7pm and certainly no later than 8pm. 

TOP TIP: If your toddler is NOT going to bed before 9pm you should take a look at the daytime nap schedule and make sure they are not napping too late in the afternoon.

Is There a 15 Month Old Sleep Regression?

Yes and no…

Sleep regressions can occur at any age but there are certain times when they are more likely to happen. 

Mainly at 4 months, 6 months, between 8 and 10 months, 12 months old and around 18 months old.

If your baby’s established sleep patterns are disrupted with them fighting sleep, increased nighttime wakings and restlessness then they are very likely experiencing a short-term sleep regression.

Is a 3 Hour Nap Too Long For A 15 Month Old?

Usually, a 3 hour nap is too long for a 15 month old. 

However, if your little one is only taking 1 nap a day then a 3 hour nap after lunch is OK. 

Bear in mind that a 15 month old should not nap for more than 3 hours a day so if they have had a morning nap… I would not recommend letting them sleep for more than 2 hours in the afternoon to avoid it impacting bedtime.

Why Is My 15 Month Old Waking At 4am?

If your 15 month old is suddenly consistently waking at 4 am it may be due to a number of reasons:

TOP TIP: Finally, try to treat early morning waking as you would any nighttime wakings… Keep interactions low-key and encourage your little one to re-settle. Offer something to play with like a favourite toy or book to keep your child occupied for a short while so you go back to bed for a precious few minutes!
