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:

15 Month Old Nap Schedule

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. 

How Many Naps For 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.

15 Month Old Wake Window

Your 15 month old wake window will continue to get longer and longer. Starting at 5 hours of awake time, they will steadily increase their wake window to 6 hours and may drop to one nap and sleep for longer periods at night until they stop napping completely.

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 to ensure your toddler gets enough sleep to support their brain’s growth and development as well as their physical development.

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

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.
