Postpartum Psychosis Warning Signs: When to Call 911

The short answer: If someone who recently gave birth is hearing or seeing things that aren't there, believes things that can't be true, is severely confused, or is acting in a way that could hurt her or the baby: call 911 or go to the nearest emergency room now. Don't wait for a therapy appointment, including with me. Postpartum psychosis is a medical emergency, and it is treatable in a hospital.

Everything below is for the hour after you've made that call, or for the partner and family members trying to figure out whether this is that.

What it looks like

Postpartum psychosis is rare, and it is not a worse version of postpartum depression. It usually starts fast, in the first days or weeks after birth, and it changes how a person perceives reality. A mom may:

• Hear voices or see things others don't
• Hold fixed beliefs that make no sense to anyone else: that the baby is in danger from a specific unseen threat, that she has special powers or a mission, that something is terribly wrong with her body or the baby's
• Be badly confused, unable to follow a conversation or track time
• Swing between agitation and flatness, or stop sleeping entirely without seeming tired
• Not recognize that anything is wrong

That last one matters most for the people around her. She may insist she's fine. If what you're seeing doesn't make sense, trust what you're seeing. The NHS has a clear description if you want to compare notes while someone else dials.

When it usually starts

According to the NHS, symptoms usually start suddenly within the first two weeks after birth, often within hours or days, and more rarely several weeks later. Postpartum Support International notes it can be experienced up to a year postpartum. It's uncommon: the NHS puts it at around 1 in 1,000 mothers. Rare is not the same as impossible, which is why it's worth every family knowing the signs.

Postpartum psychosis vs. postpartum depression vs. scary thoughts

It's a fair question, because the words overlap. What follows is a guide for knowing what to do next, not a way to diagnose anyone; only a clinician can assess an individual situation.

For a walk-through of how postpartum psychosis and postpartum depression differ, read postpartum psychosis vs. depression: the critical differences. For the difference between postpartum anxiety and OCD, see postpartum OCD vs. anxiety.

If you're the partner, parent, or friend

You don't need to diagnose anything. Tell emergency staff three things: she gave birth recently (say how long ago), what you've noticed, and whether you're worried about immediate safety. Something like: "She had a baby three weeks ago and she's suddenly very confused and hearing things. We need help now."

If you can, bring or note when it started, how she's been sleeping, and any medications or substances. Stay with her; don't leave her alone with the baby until the medical team says otherwise. Follow their instructions, even when she protests.

If you're supporting her through recovery afterward, this partner's guide to supporting postpartum mental health is a good next read, for later.

Scary thoughts are not psychosis

I want to say this clearly, because it's the thing moms Google at 2 a.m. in a panic. Having an intrusive, horrifying thought about harm coming to your baby, and being sickened by it, is extremely common and is not psychosis. In psychosis, the beliefs feel true and the person often doesn't experience them as alarming. If you're terrified by your own thought, that terror is a sign your reality-testing is intact. I've written about scary postpartum thoughts and what they usually mean. Only a clinician can assess any individual situation, but the two experiences are genuinely different.

If intrusive thoughts are what you're living with, they're very treatable. The urgent signs still apply to you too: if you think you might act on a thought, can't keep yourself or your baby safe, or are hearing or seeing things others don't, call 911 or go to the nearest emergency room.

Who's at higher risk

Postpartum psychosis can happen to anyone, and the Royal College of Psychiatrists notes it often comes "out of the blue," even in women who've never been unwell before, and that it isn't caused by anything she or her partner did. Risk is higher, according to the NHS, the Royal College, and Postpartum Support International, for women who:

• Have bipolar disorder, schizoaffective disorder, or schizophrenia
• Had postpartum psychosis after a previous pregnancy
• Have a close family member (such as a mother or sister) who had postpartum psychosis

PSI also notes that prolonged lack of sleep, such as going days without any sleep, may play a part, which is one more reason to protect sleep if you're in a higher-risk group.

If any of those apply to you, the most useful thing you can do is tell your OB or midwife, and your psychiatrist if you have one, ideally before or early in pregnancy, so the people caring for you can make a plan together. Ask them how your history affects your own risk, and what the plan is for the first weeks after birth.

After the emergency

Treatment almost always begins in a hospital, with medication and close care, and most women recover fully. When she's discharged, ask the team: who coordinates her care now, what the family should watch for, and which changes mean another urgent call. Recovery continues at home for months, and outpatient therapy often becomes part of it later. That's where someone like me comes in, once the acute phase is over and the treating team agrees.

In general terms, treatment is led by a psychiatric team, who decide on medication and the level of care. The Royal College of Psychiatrists notes that it can last several weeks or longer. Recovery isn't on a fixed timeline, and it's normal for families to have a lot of questions; write them down and bring them to the team.

The right number for the right need

• Emergency (immediate danger, possible psychosis): 911 or the nearest ER
• Crisis support: call or text 988
• Non-emergency maternal mental health support, 24/7: call or text 1-833-852-6262
• Information and referrals: the PSI HelpLine, 1-800-944-4773. It is not an emergency line.

If you're not sure what level of help a situation needs, this guide on when to seek emergency help postpartum can help. When in doubt about psychosis, treat it as an emergency.

My practice is not an emergency service. If you're reading this because the crisis has passed and you're looking for the next step, a free 15-minute consultation is the place to start.
