I am always talking to parents around Essex about short naps and they can be incredibly frustrating. If your baby is having short naps and they are rested, happy and sleeping well overnight, there is no need to change anything! However, if they are struggling and nights are hard, a few changes could make a huge difference.
Is my baby just a bad napper? Probably, not, it is likely they are just responding to the biology of sleep. The reason this length of nap is so common is because, from around four months of age, this is roughly the length of a single sleep cycle. Ideally, a nap would link two or sometimes three sleep cycles, depending on the time of day the nap is happening.
If your baby regularly wakes after one sleep cycle, the reassuring news is that there is usually a reason behind it. With a few small adjustments, it’s often possible to help naps become longer and more restorative.
In most cases, short naps happen for one of five reasons: overtiredness, undertiredness, the sleep environment, reliance on sleep props or discomfort.
1. Overtiredness: Too Much Awake Time Before a Nap
One of the most common reasons for short naps is overtiredness. It can feel tempting to keep your baby awake a little longer in the hope they will sleep better, but this can often have the opposite effect.
When babies become overtired, their bodies release stress hormones such as cortisol. These hormones can make it harder for them to fall asleep and, importantly, harder for them to stay 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. This blog explains this in a bit more detail.
Watching for early tired signs such as yawning, rubbing eyes or becoming quieter and less engaged can help you time naps more closely to when your baby is ready to sleep. If short naps are happening regularly, gently reducing awake time may help your baby transition between sleep cycles more easily.
2. Undertiredness: Not Quite Ready for Sleep
Sometimes the opposite can be true. If a baby hasn’t built enough sleep pressure before their nap, they 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, babies simply may not have been awake long enough to need a longer sleep.
Gently extending awake time can sometimes help. You might add in 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 become overtired.
3. The Sleep Environment
Your baby’s sleep environment can also have a big impact on nap length.
If the room is too bright, babies can become more alert when they naturally stir between sleep cycles, rather than drifting back to sleep. Even small amounts of daylight can make a difference.
Creating a darker, calmer sleep space can really help support longer naps. Blackout blinds can be particularly useful and, if your baby naps on the go, a snooze shade can help reduce visual stimulation.
Noise can also disturb naps, especially in busy family homes. Continuous white or pink noise can help mask everyday sounds and create a consistent, 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 going on in our babies lives and if they are uncomfortable, it can cause short naps and a very fussy baby. Teething, vaccinations, illness, reflux, the list is endless, however if your baby is uncomfortable, they could start seeing shorter naps and needing a bit more reassurance.
Short naps are incredibly common, especially in the first year, and they are not a reflection of anything you are doing wrong and if it is working, just keep it up! If they are feeling unsustainable, get in touch and we can discuss how I can help bring some balance back into your day and night.
