Postpartum Insomnia vs. New-Baby Sleep Loss
Feeding method matters less to your sleep than how often you are woken. More on that in breastfeeding and postpartum depression.
Almost every new parent sleeps less. But there is an important difference between not getting the chance to sleep and not being able to sleep when you do get the chance.
- Infant-related sleep disruption: you are exhausted because the baby wakes you, but when you lie down with time to rest, you fall asleep.
- Postpartum insomnia: the baby is asleep, someone else has the night feed, and you still lie awake, can’t get back to sleep after a feed, or wake long before you need to.
That distinction matters because insomnia disorder is diagnosed only when poor sleep happens despite adequate opportunity to sleep. Researchers found that ignoring this rule inflates insomnia rates two- to fourfold. Both situations still take a toll on mood, so both deserve attention.
For a sense of what is typical: in one U.S. study that measured sleep with wrist monitors, mothers averaged about 5.5 hours of nighttime sleep at 4 and 8 weeks after birth, and 65% slept 6 hours or less.
How Common Is Postpartum Insomnia?
The answer depends on what is being counted.
| What was measured | How common |
| Insomnia disorder, by clinical interview that accounts for sleep opportunity | About 5% to 12% after birth |
| Clinically significant insomnia pattern across pregnancy and the first year | About 13% to 18% |
| Insomnia symptoms on a questionnaire (Norway) | About 60% at 8 weeks, still 41% at 2 years |
So “most new moms have insomnia” is true only for symptoms. A true insomnia disorder affects closer to 1 in 10.
Signs of Postpartum Insomnia
- Lying awake for a long time even when the baby is asleep
- Being unable to fall back asleep after night feeds
- Waking very early and not getting back to sleep
- Feeling “wired but tired” or listening for the baby when you could be sleeping
- Racing or worried thoughts at bedtime
- Dreading bedtime because you expect not to sleep
Sleeping too much or too little is also a symptom of postpartum depression, so trouble sleeping can be part of a bigger picture.
Insomnia and Postpartum Depression
- A meta-analysis found a moderate link between insomnia and depression symptoms around pregnancy and birth, including in women with no history of depression.
- The relationship runs both ways: poor sleep raises the risk of depression, and depression disrupts sleep.
- In first-time mothers, those who rated their sleep as poor at 6 weeks had more than 3 times the odds of depression symptoms, even though sleep measured by wrist monitors was not linked. How rested you feel seems to matter.
- Not every study agrees. One meta-analysis found poor sleep quality, but not insomnia specifically, predicted postpartum depression, and no study has proven that sleep loss causes it.
Insomnia is also closely tied to anxiety. If worry keeps you awake, see postpartum anxiety or take the GAD-7.
When Not Sleeping Is an Emergency
Postpartum psychosis is rare, affecting 1 to 2 of every 1,000 births, but it is a psychiatric emergency. It usually begins 3 to 10 days after birth. Insomnia is often the earliest symptom, and in a study of women with bipolar disorder, losing a full night of sleep around labor was linked to about 5 times the odds of postpartum psychosis.
Get help immediately if you or someone you love:
- Cannot sleep at all for a night or more, especially in the first weeks after birth
- Seems confused, agitated or unusually energetic
- Sees or hears things that aren’t there, or holds strange beliefs
- Behaves in a way that is out of character or dangerous
People with psychosis often do not realize anything is wrong, so family members need to know these signs. Call 911 or go to the emergency room. If you have a history of bipolar disorder or postpartum psychosis, ACOG recommends a prevention plan during pregnancy that includes protecting sleep.
Treatment for Postpartum Insomnia
Cognitive Behavioral Therapy for Insomnia (CBT-I)
CBT-I is a structured program that changes the habits and thoughts that keep insomnia going. It is the best-studied treatment, with one important caveat: most of the strong trials were done during pregnancy.
- In a trial of 208 pregnant women, a digital CBT-I program produced a large improvement in insomnia, and 44% reached remission compared with 22% with standard care. Depression and anxiety symptoms also improved.
- When those women were followed after birth, more of the CBT-I group were in remission from insomnia, and probable major depression at 3 months postpartum was 4% vs. 18%.
- In a separate trial, in-person CBT-I during pregnancy outperformed an active comparison treatment.
- After birth, the evidence is still early: a small study of 12 postpartum women with depression and insomnia showed better sleep efficiency, and a network analysis of trials found CBT-I effective 4 to 12 months postpartum, though with low certainty.
Sleep advice alone is not enough. In two randomized trials, prenatal sleep education and a hospital-to-home sleep program did not lead to lasting improvements in mothers’ sleep.

Protecting a Block of Sleep
Many families try to give the recovering parent a longer stretch of uninterrupted sleep, for example by having a partner take one night feed. It is a sensible idea, but it has not been tested in trials for its effect on mood. A few points from the research:
- Switching to formula at night does not reliably mean more sleep. In observational studies, mothers who breastfed at night averaged 30 to 45 minutes more sleep than those using formula at night. These studies did not look at a partner giving pumped milk.
- For people at high risk of mania or psychosis, protected sleep is a clinical priority. ACOG says skipping overnight breastfeeding to preserve sleep can help in the early phase of treatment.
Sleep Medications While Breastfeeding
Talk to your prescriber before taking anything. According to the NIH’s LactMed database:
| Medication | What LactMed says |
| Melatonin | Short-term use of usual doses in the evening is unlikely to harm a breastfed baby, but no safety data exist |
| Diphenhydramine (Benadryl) | Small, occasional doses of 25 mg or less are not expected to harm the baby; larger or prolonged doses may reduce milk supply |
| Trazodone | Low levels in milk, not expected to cause problems, especially after 2 months of age |
| Zolpidem (Ambien) | Some experts recommend against it while breastfeeding due to limited data; watch the baby for sleepiness and poor feeding |
When insomnia comes with depression or anxiety, treating those conditions often improves sleep too. See antidepressants during pregnancy and breastfeeding.
What You Can Do Now
- Tell your provider if you can’t sleep even when you have the chance, and ask about CBT-I, including digital programs.
- Get screened for depression and anxiety, since they often come with insomnia.
- Ask for help so you have some protected time to rest.
- Know the emergency signs above, and make sure your partner or family knows them too.
Call or text the National Maternal Mental Health Hotline at 1-833-TLC-MAMA (1-833-852-6262), 24 hours a day. If you have thoughts of harming yourself, call or text 988.
Frequently Asked Questions
What is postpartum insomnia?
Trouble falling or staying asleep after having a baby, even when you have the chance to sleep. It is different from losing sleep because the baby wakes you.
How long does postpartum insomnia last?
It varies. In a Norwegian study, insomnia symptoms were reported by 60% of mothers at 8 weeks and still by 41% at 2 years, so it does not always resolve on its own.
Can lack of sleep cause postpartum depression?
Poor sleep and depression are linked in both directions, but studies have not proven that sleep loss causes postpartum depression.
Is it normal to not be able to sleep after giving birth?
Some sleep disruption is normal. Being unable to sleep when you have the chance, for weeks, is worth raising with your provider. Not sleeping at all for a night or more, with confusion or unusual behavior, is an emergency.
What can I take for insomnia while breastfeeding?
CBT-I is the preferred first treatment. LactMed considers short-term melatonin and small occasional doses of diphenhydramine unlikely to harm a breastfed baby, but talk to your prescriber first.
Does postpartum insomnia go away?
It often improves, but for many parents it lingers. CBT-I can help.
