Today I have been to a lovely brunch in Solihull and was asked by a couple of families about short naps and how exhausting and frustrating they can feel. If your baby is waking after a short nap but is happy, settled and sleeping well overnight, there may not be anything you need to change. However, if short naps are leaving your little one overtired and nights are becoming difficult, it is often a sign that some small adjustments could really help.
One of the big questions parents ask me is whether they simply have “a bad napper”. In my experience, this is rarely the case. Babies’ sleep changes at around four months and, after this stage, a sleep cycle will naturally be around 30 to 45 minutes long. This means what we are often seeing with short naps is your baby completing one full sleep cycle. More often, babies are responding to how sleep naturally works. What we would ideally like to see is babies being able to move into a second or even third sleep cycle, depending on the time of day.
If your baby regularly wakes after one short sleep cycle, there is usually a reason behind it rather than it being “just the way they are”. Sometimes a few gentle changes can make a significant difference and help your little one transition from one sleep cycle to another and have a longer nap.
I am going to take a look in more detail at some of the common reasons behind short naps. These can include overtiredness, undertiredness, an overstimulating sleep environment, relying on external support to fall asleep or physical discomfort.
1. Overtiredness: Too Much Awake Time Before a Nap
One of the most common reasons for short naps is overtiredness. It is very easy to think that keeping your baby awake a little longer will help them sleep better, but this can often have the opposite effect.
When babies stay awake beyond the point they are ready for sleep, they can become overtired and start producing stress hormones such as cortisol. This can make it more difficult for them to settle calmly to sleep and also make it harder for them to move between sleep cycles once asleep.
If your baby wakes after 30–45 minutes upset, crying or seeming unsettled, overtiredness may be playing a role.
Adjusting awake windows can make a big difference. Every baby has an ideal amount of awake time before they are ready to sleep, and this naturally changes as they grow.
Watching for early tired signs such as yawning, rubbing eyes or becoming quieter and less engaged can help you time naps around when your baby is naturally ready to sleep. If short naps are happening regularly, gently reducing awake time may help your baby transition between sleep cycles more easily and support longer, more restorative naps.
2. Undertiredness: Not Quite Ready for Sleep
This is where it can feel a bit confusing because sometimes the opposite can be true. If it is too early for your little one to go to sleep, they will not have built enough sleep pressure and may only sleep for one cycle before waking.
If your baby wakes from a 30–45 minute nap happy and content, rather than upset or grumpy, undertiredness could be the reason.
In this situation, your baby may simply not have been awake long enough to build enough sleep pressure for a longer nap.
You can gently extend awake time and this should help your baby build the right amount of sleep pressure for a longer nap. You could also add a little more stimulation before naps such as tummy time, a walk outside or some sensory play.
The key is finding that balance where your baby is tired enough to sleep well, but not so tired that they tip over into overtiredness.
3. Your Baby’s Sleep Environment
The environment your baby sleeps in can also make a difference to naps. We can spend lots of time looking at timings and routines, but sometimes it is worth thinking about what is happening around your little one while they are asleep.
If the room is bright, babies can become more alert when they naturally stir in their sleep rather than drifting back off again. Even small amounts of light can make a difference.
Creating a darker and calmer sleep environment can sometimes help support longer naps. Blackout blinds can be useful and, if your baby naps on the go, reducing visual stimulation can also help support sleep.
Noise can also affect naps, especially in busy family homes where there is often lots going on. White or pink noise can help mask background sounds and create a more consistent and calming sleep environment.
4. Sleep Associations
Some babies wake after one sleep cycle because they rely on support such as feeding, rocking or being held to fall asleep. When they naturally stir between sleep cycles, they look for the same help to settle back to sleep.
If contact naps are working well for your family, there is absolutely no need to change anything. Many parents enjoy this time, and it can be a lovely way to connect with your baby.
However, if short naps are starting to feel unsustainable, gently supporting your baby to develop independent sleep skills can help them link sleep cycles more easily.
Placing your baby down awake and allowing them the opportunity to settle themselves can help them learn how to drift between sleep cycles. This does take time and consistency, but it can make a real difference to nap length and overall sleep quality.
5. Discomfort
There is a lot to think about when helping our babies nap well and discomfort can sometimes play a part in shorter naps. If your little one is feeling uncomfortable for any reason, they may be more likely to wake sooner and need a little extra support and reassurance.
Teething, vaccinations, illness, reflux or even a blocked nose can all affect sleep. The list can sometimes feel endless, and during these times it is very normal for sleep to feel a little more unsettled.
Short naps are incredibly common, especially during the first year. If your little one is happy, rested and things are working well for your family, there may not be anything you need to change. However, if naps are starting to feel unsustainable and are having an impact on your days or nights, small changes can sometimes make a really big difference.
