You finally got your baby down. The house is quiet. And you are lying in the dark, wide awake, staring at the ceiling. This is one of the most disorientating experiences of new parenthood: exhaustion so deep it aches, yet sleep won’t come when the chance is finally there.
If this sounds familiar, you are not alone, and you are not doing anything wrong. Postpartum insomnia is common, it is different from ordinary new-parent tiredness, and — importantly — it is treatable. As a clinical psychologist specialising in CBT-I (cognitive behavioural therapy for insomnia), I see this pattern often in new parents who assumed their sleep would simply “sort itself out” once the baby settled. For many, it doesn’t, unless the insomnia itself is addressed.
What postpartum insomnia actually is
It’s worth separating two very different things that often get lumped together:
- Sleep deprivation is not getting enough opportunity to sleep, because a baby needs feeding, settling or comforting overnight. The fix is more sleep opportunity, and it typically improves as the baby’s sleep matures.
- Postpartum insomnia is difficulty falling asleep, staying asleep, or getting back to sleep, even when there is a genuine opportunity to rest. This is a sleep disorder in its own right, not simply a symptom of having a newborn.
According to Sleep Foundation data, more than two-thirds of people who give birth experience poor sleep quality in the six months afterwards, and for a significant number, sleep problems continue well beyond that window. Hormonal shifts, anxiety about the baby, physical recovery and disrupted routines all play a part in the early weeks. But when the wakefulness persists after the initial adjustment period, something else is usually keeping it going.
Why sleep doesn’t improve even after the baby starts sleeping through
This is the part that catches so many new parents off guard. The baby starts having longer stretches at night, everyone tells you “you must be getting more sleep now” — and yet you’re still lying awake for an hour, or waking at 3am and staring at the clock, heart racing, mind racing.
Sleep researchers have a clear explanation for this. During those early months of frequent waking, the body and mind learn new associations: lying in bed becomes linked with alertness, listening out, checking the monitor, or worrying about the next feed. Many parents also start napping at odd times, spending long stretches in bed awake, or lying down “just in case” they get a chance to rest. These are completely understandable responses to survival-mode parenting — but they are also exactly the ingredients that keep insomnia going long after the original cause (a waking baby) has resolved.
In other words, the insomnia becomes self-sustaining. This is precisely what CBT-I insomnia treatment is designed to interrupt: not the baby’s sleep, but the learned patterns and anxious arousal that now drive your own.
The link between postpartum insomnia and low mood
Insomnia and postpartum depression are closely intertwined, and the relationship runs both ways. Poor sleep is a recognised risk factor for postnatal depression and anxiety, and low mood, in turn, makes sleep harder — a genuinely difficult cycle to break alone.
This connection is exactly why CBT-I is now being studied so seriously in the perinatal period. A 2024 randomised controlled trial found that cognitive behavioural therapy for insomnia delivered during pregnancy reduced insomnia symptoms and had knock-on benefits for postpartum depressive symptoms, largely because improving sleep reduced one of the key drivers of low mood. If you’re also feeling persistently low, anxious or overwhelmed, it’s worth reading more about insomnia and anxiety, and how they interact, and speaking to your GP or health visitor about how you’re feeling — you don’t have to manage this alone.
Why generic sleep hygiene advice often misses the point
New parents are given plenty of well-meaning advice: “sleep when the baby sleeps,” “keep the room dark,” “avoid screens before bed.” These tips aren’t wrong, but they rarely touch the real problem once insomnia has taken hold. Lying in bed for longer “just in case,” napping unpredictably through the day, or trying to force sleep through sheer willpower can actually make wakefulness worse, not better.
If you’ve tried all the standard sleep tips and you’re still lying awake, that’s not a sign you need to try harder — it’s usually a sign that the problem needs a different kind of approach. You can read more about why this happens in our guide to waking up during the night and how to fall asleep more easily.
How CBT-I treatment helps postpartum insomnia
NICE (the National Institute for Health and Care Excellence) recommends CBT-I as the first-line treatment for chronic insomnia in adults of any age, ahead of sleeping tablets. For new parents, a good CBT-I programme is adapted to the realities of life with a baby — it doesn’t ask you to follow a rigid, adult-only sleep schedule, and it never asks you to let your baby “cry it out.” Instead, it works with your situation and helps you:
- Rebuild your body’s confidence that bed is a place for sleep, not vigilance or worry
- Reduce the anxious “trying too hard” pattern that keeps the brain alert at bedtime
- Adjust daytime naps and rest strategically, without making night-time sleep harder
- Address racing thoughts and new-parent worry that flare up the moment the house goes quiet
- Build a flexible, realistic routine that can bend around night feeds and unpredictable nights
This is a fundamentally different approach from generic tips, and it’s backed by a growing body of research. If your sleep has stopped improving even though the baby’s has, it’s worth exploring proper insomnia treatment rather than waiting it out — postpartum insomnia rarely resolves through willpower alone once it has become established, and there’s no need to keep struggling through it. To understand the evidence behind this approach in more depth, see why CBT-I works.
Practical steps you can try tonight
While a full CBT-I programme addresses the underlying pattern, a few adjustments can help in the meantime:
- Get out of bed if you’re wide awake. Lying there willing yourself to sleep tends to backfire. If you’ve been awake for what feels like 20 minutes or more, get up, sit somewhere dim and calm, and return to bed when you feel sleepy again.
- Keep naps short and earlier in the day where you can. Long or late naps can eat into your night-time sleep drive, even when you’re desperate for rest.
- Separate feeding from full wakefulness. Keep light and stimulation low during night feeds so your body doesn’t learn that the middle of the night is “on” time.
- Notice clock-watching. Checking the time repeatedly during a wakeful stretch tends to increase anxiety and make falling back asleep harder, not easier.
- Be patient with yourself. Some disrupted sleep is a normal, temporary part of early parenthood. It becomes a problem worth treating when it persists, feels distressing, or doesn’t track with your baby’s own sleep changes.
When to seek help
It’s time to look into proper support if:
- You’re still struggling to fall or stay asleep even on nights when your baby sleeps well
- You feel dread or anxiety at bedtime about whether you’ll be able to sleep
- Your sleep problems have lasted more than a few months
- Low mood, anxiety or intrusive worries are building alongside the sleeplessness
If any of this rings true, please also speak to your GP or health visitor, particularly if you’re noticing symptoms of postnatal depression or anxiety — they can rule out other causes and point you towards the right support alongside sleep treatment. Our complete guide to insomnia is a good place to understand the bigger picture, and our team is also happy to talk it through — you can get in touch here.
In summary
Postpartum insomnia is common, but it isn’t something you simply have to endure until your baby “sleeps better.” When sleeplessness continues after the initial newborn stage, it’s often being kept going by learned patterns of anxiety and arousal around sleep — patterns that respond well to CBT-I, the treatment recommended by NICE as the first-line approach for insomnia. You don’t need to wait it out alone, and you don’t need to choose between caring for your baby and looking after your own sleep.

Frequently asked questions
Is postpartum insomnia normal?
Some disrupted sleep is a normal part of early parenthood, since babies wake frequently overnight. However, ongoing difficulty falling or staying asleep — even when you have a genuine chance to rest, such as when the baby is sleeping well — is a recognised sleep disorder called postpartum insomnia, not just a normal consequence of having a newborn. It’s common, but it isn’t something you simply have to live with.
How long does postpartum insomnia usually last?
For many parents, sleep gradually improves over the first six months as the baby’s sleep matures and routines settle. However, research shows that a significant number of new parents continue to experience poor sleep quality well beyond this point, particularly once anxious patterns around sleep have taken hold. If your sleep hasn’t improved despite your baby sleeping better, it’s worth addressing the insomnia directly rather than waiting.
Can I do CBT-I while caring for a newborn?
Yes. CBT-I for new parents is adapted to fit around night feeds, unpredictable nights and the realities of caring for a baby. It doesn’t require a rigid schedule and works with your circumstances rather than against them, gradually helping your body relearn how to fall and stay asleep.
Should I take sleeping tablets for postpartum insomnia?
Medication decisions, especially during breastfeeding, should always be made with your GP, who can advise on what is safe for you and your baby. NICE guidance recommends CBT-I as the first-line treatment for insomnia in adults, as it addresses the underlying causes rather than masking symptoms. Never start, stop or change any medication without speaking to your doctor first.
