About the stories on this page: they're composites, built from more than one client, with names and identifying details changed. No story describes a real person. How we write client stories

ERP for postpartum OCD looks like a series of planned, ordinary parenting tasks you've been avoiding, done in order from easier to harder, without the rituals that usually follow. Each one tests a prediction the fear makes. Below is one composite parent's plan, week by week, so you can see what actually happens in the room and between sessions.

This is an illustration, not a promise. Your plan would be built around your fears, at your pace. If you want the background first, start with what postpartum OCD is.

The short answer

  • How exposure works: Exposure works through expectancy violation, where you learn the feared outcome doesn't arrive, or that you can carry the feeling without the ritual (Craske et al., 2014).
  • Calm is not the goal: How much fear drops during an exposure did not predict how well people did afterwards (Craske et al., 2008).
  • Partners matter: Family members joining rituals or giving reassurance, called accommodation, was linked with more severe OCD across 41 studies (Wu et al., 2016).
  • Pushing thoughts away backfires: Trying to suppress a thought produced a small to moderate rebound, meaning more of the thought, in a meta-analysis (Abramowitz et al., 2001).

Who is Maya?

Maya is a composite, built from more than one parent. Seven weeks after her son was born, she got a flash of holding him under the bathwater. By the time she booked a consultation, her partner did every bath, the knife block lived in the garage, and she checked her son's breathing a dozen times a night. She'd searched do mothers who think this hurt their babies more times than she could count.

She hadn't told anyone the actual words. That was the first thing she did in the room.

What happens in the first two weeks?

The first two weeks are assessment: mapping the thoughts, every ritual and every avoidance, and checking for anything that needs a doctor, like depression or a sleep deficit that's become dangerous on its own. For Maya that map looked like this:

  • Obsessions: drowning him in the bath, stabbing him while cooking
  • Avoidance: baths, knives, being alone with him in the kitchen
  • Rituals: breathing checks, searching online, asking her partner do I seem okay to you?
  • Mental rituals: replaying the day to confirm she hadn't done anything

We also named the bully's logic out loud: you're only safe because you avoid. Every plan after this is built to test that sentence.

What does the fear ladder look like?

The fear ladder is a list of the situations you avoid, ranked by how hard they feel, each with the prediction the fear makes. Maya built hers with us. Nothing went on it she hadn't agreed to.

PracticeWhat the fear predictsHow hard (0 to 10)
Write the drowning thought down, word for word, and leave it unansweredI'll feel so sick I'll have to call someone3
Knife block back on the counter while the baby naps in the bassinetI'll keep looking at it and something will happen4
Cut vegetables with the baby in the bouncer across the kitchenThe image will come and I'll lose control6
Bath with her partner in the next roomWithout him there, I can't trust myself7
Bath alone, door open, partner out of the houseThis is the one where it happens9

It's like the gym. You don't walk in and lift 300 pounds. You start with the two-pound weights, and trust me, we can make those hard.

What do the first exposures look like?

The first exposures look small from the outside and huge from the inside. In week three Maya wrote the drowning thought on a card, exactly as it showed up, and read it. Then the hard part: no calling her partner, no searching, no reviewing. She predicted she'd feel too sick to get through the evening. She got through the evening.

By week five the knife block was back on the counter, and she was cutting vegetables with her son in the bouncer across the room. After every practice she wrote two lines: what the fear predicted, and what actually happened. Not how anxious she felt. That record is the point (Craske et al., 2008).

What happens when there's a setback?

Setbacks are part of the plan, not a sign it's failing. In week seven Maya read a news story about a parent who hurt a child. That night she checked his breathing eleven times and asked her partner twice whether she seemed okay.

We didn't start over. We named it, the bully found a new door, and went back one rung for a week. Her partner came to a session too, and learned to answer do I seem okay? with something like that sounds like the OCD asking instead of a yes. That's the accommodation piece, and it's often where partners help most.

What changed by the end?

By the end, the thoughts still showed up sometimes. What changed is that they stopped running the day. Maya gave baths. The knives lived in the kitchen. The breathing checks dropped to the ones every new parent does. When a thought came, she let it be there and kept doing what she was doing.

Sessions spaced out and she ran the plan herself, with a written list of what to do if a bad stretch came back. She fired us for the right reasons. Your plan wouldn't look exactly like this, and nobody can promise a timeline, but the shape is the same: map it, rank it, test it, keep going.

Where can you go from here?

FAQ

What Do Parents Ask About ERP?

No exposure asks you to do anything harmful. Exposures are ordinary parenting tasks you've been avoiding, planned with your therapist, at a pace you agree to. What changes is that you do them without the ritual.

It depends on the person and how long the OCD has been running. Some parents move quickly, others need longer, and we review progress with you as we go rather than promising a number.

They often do, especially during stress or sleep loss. Intrusive thoughts are normal; the goal is that they stop running your day. You leave with the plan, so you know what to do when one shows up.

No. Maya is a composite, built from more than one person, with details changed. The steps are typical of how ERP runs; your plan is built around your own fears.

How we researched this page

This page illustrates how ERP for postpartum OCD typically runs, using a composite parent built from more than one person. The approach draws on research on inhibitory learning in exposure therapy (Craske 2008 and 2014), a meta-analysis of family accommodation (Wu 2016) and a meta-analysis of thought suppression (Abramowitz 2001). The week-by-week shape is clinical practice, not trial data, and real plans vary in pace and order from person to person.

A note on my perspective

I run a private clinic that treats OCD with ERP, and I'm paid when people book with us. Read what I write with that in mind. Public and lower-cost routes exist too, and the Ontario OCD treatment guide lays them out next to ours.
