As a sleep consultant who has supported many families through this stage, I know how confusing it can feel when your baby is finally sleeping more reliably, but you are not. A question I get asked is: “Why can’t I sleep when my baby sleeps?”
These are completely normal concerns. It does not mean you are ungrateful. After weeks or months of broken nights, your body and brain often need time, and a little support, to learn that it is safe to rest again.
Why can’t I sleep when my baby finally sleeps?
When you have spent a long time listening for every rustle, your nervous system can stay on high alert. This is often called hypervigilance. Your brain has learned that night-time is when you might be needed, so even when your baby is settled, part of you may still feel “on duty”.
Cortisol also plays a part. This is a hormone involved in alertness and our response to stress. After a long stretch of fragmented sleep, it can feel much harder to switch off, even though you are tired. Many parents describe this as feeling tired and wired at the same time.
Your body clock, or circadian rhythm, can be disrupted too. Night feeds, early rising and irregular bedtimes send mixed signals about when it is day and when it is night. Until that rhythm is gently reset, you may find yourself wide awake in the early hours, even if your baby does not.
Sleep pressure is the natural drive to sleep that builds the longer we are awake. If your days have become a patchwork of short rests or late caffeine, that pressure may not be strong enough at bedtime.
The NHS in the UK notes that, on average, adults need 7 to 9 hours of sleep, although individual needs vary. I have written before about the benefits of sleep for the whole family, and this matters for you as much as it does for your child.
How can I start to reset my own sleep?
The reassuring news is that many parents can make progress by gently rebuilding their own sleep habits. This does not need to be perfect, and it does not need to happen overnight.
- Choose a consistent wake-up time, including after a difficult night. A regular morning rise helps to steady your body clock. Try to stick to your regular sleeping hours rather than lying in after a poor night.
- Get natural light in the morning. Open the curtains or step outside with your baby if you can.
- Protect a wind-down before bed. Dim the lights, put your phone away and do something calm.
- Make your sleep space as sleep-friendly as you can. A dark, comfortable and reasonably quiet room helps your brain recognise that this is a place for rest.
- If you have been awake for a while and your mind is racing, get up and do something gentle in low light, then return to bed when you feel sleepy.
- Be mindful of caffeine and alcohol later in the day, and of late meals.
- Be careful with long or late naps. A long afternoon nap can reduce the sleep pressure you need at bedtime. If you need a rest, keep it short and earlier in the day where you can.
I also talk about the wider importance of sleep health for adults and infants. The same principles apply to you, not only to your children.
When should I speak to a doctor?
Self-help is a sensible starting point, but it is not always enough, and you should never feel you have to manage this alone.
If changing your sleeping habits has not helped, you have had trouble sleeping for months, or your sleep difficulties are affecting daily life in a way that makes it hard to cope, please speak to a doctor or healthcare provider. In the UK, the NHS has advice on insomnia that you may find helpful.
It is also important to consider your mood. Difficulty sleeping, even when you get time to rest, can sometimes go alongside low mood, feeling anxious or that you cannot cope, or feeling guilty or worthless. These feelings can begin in pregnancy, soon after birth, or later, and fathers and partners can be affected too. In the UK, the NHS lists difficulty sleeping, even when you get time to rest, as one of the possible symptoms of postnatal depression.
If this sounds familiar, please speak to your doctor, midwife or health visitor, or another healthcare provider. Asking for help does not make you a bad parent. In the UK, the PANDAS Foundation offers free, confidential peer support for parents and families affected by perinatal mental health difficulties.
If you need urgent help, or are having thoughts of harming yourself, contact your doctor, call your local emergency number, or get in touch with a local crisis line.
Final reassurance from a sleep consultant
I know how disappointing it can feel when your baby’s sleep improves but yours does not follow straight away. You are not expected to bounce back overnight. Your body has been doing a very important job, and it may simply need a clearer routine and enough reassurance that night-time is no longer an emergency.
Just as I often say about letting go of the idea of perfect baby sleep, your own sleep does not need to be flawless either. It needs to be realistic, healthy and kind.

FAQs
1. Why can’t I sleep when my baby sleeps?
Often it is a mix of hypervigilance, a disrupted body clock and altered sleep pressure after months of broken nights. Your baby may have learned a new pattern, whilst your nervous system is still catching up.
2. How long will it take for my sleep to settle?
This varies from person to person. Some parents notice a difference within a couple of weeks of a more consistent routine. If your sleep is not improving, or you have been struggling for months, speak to a doctor.
3. Should I still nap when my baby naps?
If night sleep is the main difficulty, long or late naps can make it harder to fall asleep at bedtime. A short rest earlier in the day can still be helpful if you need it.
4. Could this be postnatal depression or anxiety?
It might be, especially if you also have a low mood, feel anxious, or find it hard to cope. Difficulty sleeping despite having time to rest can sometimes go alongside these feelings. Please speak to your doctor, midwife or health visitor, or another healthcare provider, if you are unsure.
