The image of dropping the baby on the stairs. The knife you now put away. What the research says about how common this is and what it does and does not mean.
You are carrying the baby down the stairs and your mind shows you, in detail, the two of you falling. Or you are at the kitchen counter and the knife is there and something in your head says the words. And then you spend the rest of the day quietly horrified at yourself, and you do not tell anyone, because how could you.
Here is the finding that changes the shape of this. In a study that followed 763 pregnant women in British Columbia through the postpartum period, 95.8 percent reported unwanted intrusive thoughts of their baby coming to accidental harm, and 53.9 percent reported unwanted thoughts of intentionally harming their baby. Not fleeting worries. Interview-assessed unwanted intrusive thoughts. The researchers, Collardeau, Fairbrother and colleagues, writing in the Journal of Clinical Psychiatry in 2024, called them a normative and typically self-resolving occurrence in the postpartum period.
That number does not mean nothing is wrong. It means the thought itself is the wrong thing to measure. What matters is what happens next, and that is where postpartum OCD comes in.
This is the part no one explains, and it is the thing worth taking away.
Minds generate unwanted content. They do it more when the stakes are higher, and there is no higher stake than a newborn you are responsible for every hour. The more terrifying a possibility is, the more attention your mind gives it, which is a reasonable system working exactly as designed and feeling like evidence of something monstrous.
So if you are looking for the signal, do not look at the thought. Look at these instead:
Those are the markers the International OCD Foundation describes for perinatal obsessive-compulsive disorder: the obsession is the unwanted thought, and the compulsion is whatever you do to make the feeling stop. The organization puts perinatal OCD at roughly 2 to 3 percent of parents, and notes recent work suggests it may be higher. Fairbrother and colleagues found OCD occurs more often in pregnancy and the postpartum period than in the general population.
The cruel part is that the avoidance is what keeps it running. Every time you hand the baby over at the stairs, the fear is confirmed as reasonable and the belief that you cannot be trusted goes unchallenged. The IOCDF is direct that avoiding triggering situations worsens symptoms over time.
The same 2024 study tracked timing, which is useful if you are in the middle of it. Accidental-harm thoughts were most intense around 5.7 weeks postpartum. Intentional-harm thoughts peaked within the first eight weeks. More than 40 percent of the women reported moderate or extreme distress during that peak window. By six months, the thoughts had decreased or fully resolved for most participants.
Two honest readings of that. If you are at week six and feel like you are losing your grip, you are at the statistical worst of it, and that is information rather than a prediction. And if it has not eased by a few months in, or it is taking more of your life rather than less, that is the point where it is worth bringing to someone rather than waiting it out.
This is distinct from postpartum anxiety more broadly, which has its own shape. Postpartum Anxiety Is More Than the Baby Blues covers that, and I Love My Baby, So Why Do I Feel Like This? covers postpartum depression, which frequently sits alongside both.
Many people who have these thoughts are secretly afraid they are the beginning of something that ends in the news. The two are genuinely different, and the differences are specific enough to be useful.
With OCD, the thoughts are unwanted and distressing, you recognize them as not reflecting what you want, and what you do in response is aimed at preventing harm. Insight is usually intact. The IOCDF states plainly that it is very unlikely the thoughts will be acted upon.
Postpartum psychosis is a different condition involving hallucinations or delusions, where the thoughts may not be distressing at all, reality testing can be lost, and symptoms may come and go. It is a medical emergency. If you are seeing or hearing things others do not, if the beliefs feel true rather than intrusive, or if you are not distressed by thoughts of harm, that needs urgent medical attention today rather than an appointment next month.
One more thing, and it is the reason this article spends a paragraph on the distinction. In a 2020 study by Mulcahy and colleagues, nearly 70 percent of perinatal health practitioners did not accurately identify infant-harm obsessions, and 30.8 percent misidentified them as psychotic. That is not a reason to avoid telling anyone. It is a reason to have the words ready. Saying "these are unwanted intrusive thoughts, they distress me, I do not want to act on them, and I am avoiding things because of them" gives whoever you tell the information they need to recognize what they are looking at.
For OCD generally, the treatment with the strongest evidence is cognitive behavioral therapy with exposure and response prevention, which works on the compulsion rather than arguing with the thought. Why Can't I Stop Checking, Even When I Know It's Fine? explains how that approach works in practice.
In the perinatal context, the IOCDF notes that a 2015 study by Glazier and colleagues found some professionals recommending contraindicated strategies, including antipsychotics in place of cognitive behavioral therapy or SSRIs. Knowing that the recommended direction is therapy, with or without medication, rather than treatment for psychosis, is worth having in your pocket.
And if the thoughts are in the normative range and simply frightening, the researchers' own recommendation was education: they argued for more being done to normalize these thoughts and reduce the distress they cause. Which in practice means something as ordinary as finding out that almost everyone has them, and that having them is not the beginning of anything.
You do not have to have decided whether this is "bad enough." If you have been carrying something you have not said out loud, saying it is the useful move, and a therapist is not going to be alarmed by it.

Something to hold onto in the meantime. The horror you feel about the thought is the strongest available evidence of what you actually want. Someone who wanted to hurt their baby would not be reading this and would not be frightened.

Reach OutUnwanted thoughts of harm are reported by most new parents. In a 2024 study following 763 women, 95.8 percent reported unwanted intrusive thoughts of accidental harm to their baby and 53.9 percent reported thoughts of intentional harm. The researchers described them as a normative and typically self-resolving occurrence. Having them does not mean you want to act on them.
Postpartum or perinatal OCD is obsessive-compulsive disorder occurring in pregnancy or after birth, where unwanted intrusive thoughts are followed by compulsions aimed at preventing harm or reducing distress. Common compulsions include avoiding bathing or diaper changes, removing or hiding sharp objects, not being alone with the baby, checking, and asking for reassurance. The International OCD Foundation estimates it affects roughly 2 to 3 percent of parents.
Look at the consequences rather than the content. How much of your day the thoughts take up, whether you have started avoiding ordinary care tasks or situations because of them, and whether you need to check or be reassured and find the relief does not last. Those are the markers of OCD rather than the thought itself.
No. In OCD the thoughts are unwanted and distressing, you know they do not reflect what you want, and insight is usually intact. Postpartum psychosis involves hallucinations or delusions, thoughts that may not distress you, and loss of reality testing, and symptoms may come and go. Postpartum psychosis is a medical emergency and needs urgent attention rather than a scheduled appointment.
For most participants in the 2024 study the thoughts had decreased or fully resolved by six months, with the most intense period in the first two months. If yours are taking up more of your life rather than less, or you are rearranging your routines to avoid them, that is the point to bring it to someone rather than waiting.
For OCD generally, the strongest evidence is for cognitive behavioral therapy with exposure and response prevention, which targets the compulsion rather than arguing with the thought. For frightening thoughts in the normative range, the researchers' own recommendation was education and normalization to reduce distress.
The Healing Effect is not a crisis service. If you are in crisis or thinking about harming yourself, call or text 988 to reach the Suicide and Crisis Lifeline, available 24 hours a day, 7 days a week. If you are seeing or hearing things other people do not, or thoughts of harm do not distress you, that needs urgent medical attention today. Call 988, call 911, or go to your nearest emergency department.
