Postpartum psychosis: the warning signs every family should know
Rare, sudden, and an emergency. With fast treatment, most mothers make a full recovery.
Updated October 13, 2026 · sources checked October 13, 2026
In short
Postpartum psychosis is a rare but serious illness, affecting around 1 in 1,000 mothers, that usually starts suddenly in the first 2 weeks after birth. Signs include confusion, hallucinations, strange beliefs, a very "high" or rapidly changing mood and little sleep. It is a medical emergency: call 911, 999 or 112, or go to the emergency department.
What to do right now
If you notice these signs after a birth, act immediately. Call 911 (US, Canada, Mexico), 999 (UK), 112 or 999 (Ireland), 000 (Australia), 112 (India, EU), 192 SAMU (Brazil), or go to the nearest emergency department. In the UK, the NHS also advises seeing a GP immediately for a same-day assessment, calling 111 if you cannot reach one, calling the crisis team if there is already a care plan, and calling 999 or going to A&E if anyone may be in danger. Stay with her. Do not leave her alone with the baby while you wait for help.
The warning signs
From the NHS, the NIMH and the Royal College of Psychiatrists:
- hallucinations: hearing, seeing, smelling or feeling things that are not there;
- delusions: fears or beliefs that are unlikely to be true and feel real to her;
- mania: very "high", talking or thinking very fast, much more active or sociable than usual, losing inhibitions;
- low mood: withdrawn, tearful, not eating, agitated;
- moods that swing very fast, from hour to hour;
- severe confusion, feeling in a dream world;
- paranoia and suspicion;
- not sleeping, or not wanting to sleep;
- behaviour that is completely out of character.
The NHS warns: "if you have postpartum psychosis, you may not realise you're ill. Your partner, family or friends may spot the signs and have to take action."
How common, and when
| How common | Around 1 in 1,000 mothers (NHS); incidence 0.89 to 2.6 per 1,000 in population studies (VanderKruik et al., 2017) |
| When it starts | Usually suddenly in the first 2 weeks, often within hours or days of the birth; more rarely several weeks later (NHS) |
| How it differs | Not the baby blues and not depression: the NIMH calls it "a psychiatric emergency that requires hospitalization" |
Treatment and recovery
According to the NHS, treatment usually happens in hospital, ideally with the baby in a specialist mother and baby unit. It can include medicines to treat psychotic symptoms and stabilize mood, and talking therapy later in recovery. "The most severe symptoms tend to last 2 to 12 weeks, and it can take 6 to 12 months or more to recover completely." Most importantly: "most people with postpartum psychosis make a full recovery as long as they receive the right treatment."
Afterwards, some mothers go through a period of depression, anxiety or low confidence. Peer support helps: in the UK, Action on Postpartum Psychosis offers peer support for women and families; in the US, Postpartum Support International runs online groups for survivors in recovery.
Who is at higher risk
The Royal College of Psychiatrists gives these approximate risks:
| Situation | Approximate risk |
|---|---|
| No history, no close family history | 1 in 1,000 |
| No history, but mother or sister had postpartum psychosis | 3 in 100 |
| Bipolar I or schizoaffective disorder, first pregnancy | 1 in 5 |
| Bipolar I or schizoaffective disorder, and mother or sister had it | 1 in 2 |
After a previous episode, the NHS says there is about a 1 in 2 chance of another after a future pregnancy, and that the risks can be reduced with the right care. If you are at higher risk, the NHS recommends specialist care during or before pregnancy and a pre-birth planning meeting at around 32 weeks with everyone involved, so that a written plan explains how to get help quickly.
It can also happen "out of the blue", as the Royal College puts it, to someone with no history.
Not to be confused with intrusive thoughts
Many new mothers have unwanted, horrifying thoughts of their baby being harmed. When those thoughts feel "not me", come without confusion or hallucinations, and lead to avoiding or checking, they are usually anxiety or OCD, not psychosis. Read intrusive thoughts and postpartum OCD. If you are unsure, call the same day.
For partners: keep this in your phone
If, in the days or weeks after the birth, she sees or hears things, has strange beliefs, is very confused, suddenly "high" and not sleeping, or swings fast between high and low: this is a medical emergency, call now. You are allowed to act for her. Read also how partners can help, and depression in partners.
