Short answer: You can’t go fully no contact with an ex you share children with, but you can go no contact with the relationship. Keep every exchange about the kids, put it in writing, keep it brief, and cut everything else: the late-night texts, the social media checking, the “how are you really” conversations. Most co-parents call this “modified no contact,” and it works.
If you share kids with your ex, most no contact advice feels like it was written for someone else. “Block them everywhere” is not an option when you need to confirm who’s doing Thursday pickup. “Don’t respond for 30 days” doesn’t work when your seven-year-old has a fever and your ex needs to know.
So let’s be clear about the goal. You are not trying to make your ex disappear. You are trying to stop the relationship from living inside your phone. The parenting partnership stays. The romantic, emotional, and fighting channels close.
What “no contact” actually means when you co-parent
The classic no contact rule exists to do two things: give your brain a break from the person, and stop the cycle of hope, contact, and disappointment. You can get both of those benefits without cutting off communication about your children. You just have to be strict about the line between the two.
Think of your ex as a colleague on one very important project. You’d answer a colleague’s question about a deadline. You wouldn’t text them at midnight about how much you miss the old office.
What stays and what goes
| Keep (child-related) | Cut (relationship-related) |
|---|---|
| Pickup and drop-off times and locations | “Can we talk about us?” |
| Health, school, appointments, emergencies | Comments on their new partner or their life |
| Schedule changes and holiday arrangements | Rehashing why the relationship ended |
| Costs you split for the kids | Checking their Instagram, Stories, or location |
| Big parenting decisions | Small talk at handovers that drifts into old patterns |
| Short updates the other parent genuinely needs | Using the kids as messengers or informants |
If a message doesn’t change what happens for your child in the next few days or weeks, it probably belongs in the “cut” column.
Step 1: Move communication into one channel
The fastest way to reduce emotional contact is to change where contact happens. Texting is where couples flirt, fight, and make up. That history lives in the thread. Every time you open it, you see the old messages, the heart reactions, the 2am arguments.
Options that work better:
- A dedicated co-parenting app. Tools like OurFamilyWizard, TalkingParents, AppClose, and 2houses are built for this. They keep a shared calendar, expense tracking, and a message log. Some courts in the US recommend or order them in high-conflict cases, and the record can help if things get legal.
- Email only. Free, slower, and naturally more formal. Nobody writes a tearful 400-word email about the past as easily as they send a tearful text.
- A shared calendar. For schedules, a shared Google or iCloud calendar can replace half your messages entirely.
Tell your ex once, calmly: “From now on I’d like to keep kid logistics in [app/email] so we have everything in one place. For emergencies, call me.” Then stick to it. You don’t need their agreement for your side of the boundary. You only need to stop replying to non-urgent texts in the old thread, and redirect.
Step 2: Use a reply format that keeps you out of the fight
Mediator and lawyer Bill Eddy, who co-founded the High Conflict Institute, popularised the BIFF response: Brief, Informative, Friendly, Firm. It’s widely used by family lawyers and co-parenting services for exactly this situation.
- Brief: a few sentences. Long messages invite long replies.
- Informative: facts only. Times, places, decisions.
- Friendly: a neutral, polite tone. Not warm, not cold.
- Firm: it ends the exchange. No open questions about feelings.
Here’s what that looks like with a real message.
Your ex: “Honestly I can’t believe you’re making me drive across town again. You always do this. You never cared how hard this is for me. Can we just talk tonight?”
BIFF reply: “Thanks for letting me know. Pickup stays at 5pm at my place on Friday as agreed. If you want to change the location going forward, send me a suggestion in the app and I’ll look at it this weekend.”
Notice what it doesn’t do. It doesn’t defend you against “you always do this.” It doesn’t accept the invitation to talk tonight. It doesn’t explain your feelings. That’s the no contact part, built into a parenting reply.
Messages you’ll be tempted to send (and what to send instead)
| What you want to send | What to send |
|---|---|
| “The kids keep asking why you left. Hope you’re happy.” | Nothing to your ex. Talk to a friend, a therapist, or write it out first. |
| “Saw you at the school play with HER. Classy.” | Nothing. If there’s a real issue about introducing new partners, raise it later as a parenting question. |
| “I miss us. Do you ever think about trying again?” | Nothing. That’s a conversation for when you’re both clear-headed, if ever. |
| “Maya was asking about you. She drew this for you ❤️” | “Maya made you a drawing, I’ll put it in her bag for Saturday.” (Facts, no emotional hook.) |
Step 3: Make handovers boring
Handovers are where modified no contact usually breaks. You see them in person, they look tired or good or happy, and suddenly you’re standing on the doorstep having the conversation you swore you wouldn’t have.
- Keep them short. Bags ready, shoes on, a quick goodbye to the kids. Two minutes is plenty.
- Use neutral ground if you need to. School pickup, a grandparent’s house, or a public place removes the “come in for a coffee” moment.
- Script your exit. “Okay, have a great weekend, guys. See you Sunday.” Then turn and go.
- Don’t do handovers right after drinking or on nights you already feel shaky. Ask a family member to step in if you can.
If your ex tries to start a relationship conversation at the door, you can say: “I don’t want to get into that in front of the kids. If it’s about them, send it to me in the app.”
Step 4: Close every other door
Here’s the part people skip. Most of the emotional contact in a co-parenting breakup doesn’t happen through messages. It happens when you check their profiles, scroll their Stories, or quietly ask your kids what Daddy’s new girlfriend is like.
- Mute or unfollow them on social media. You don’t need their posts to co-parent. If you’re unsure which to choose, our guide on whether to unfollow, mute or block your ex covers the options.
- Don’t use your children as a window. Asking “Was anyone else at Mum’s house?” puts your kid in the middle. Research on divorce outcomes, including Paul Amato’s long-running reviews, consistently points to ongoing conflict between parents, not the separation itself, as one of the strongest predictors of harm to children.
- Turn off location sharing unless there’s a specific, agreed safety reason for keeping it.
- Save their contact under a neutral name like “Co-parent: Sam” so it stops looking like the person you used to love.
What your kids need from you during this
You might worry that going cold on your ex will feel cold to your children. Usually it’s the opposite. Kids pick up tension fast. Calmer, shorter, more predictable contact between their parents is good for them.
- Never ask them to pass messages (“Tell your dad he’s late again”).
- Don’t criticise the other parent in front of them, even when it’s deserved.
- Let them love the other parent out loud without it costing them anything with you.
- Keep their routines steady where you can. Bedtime, school, activities.
Children don’t need to know why you’ve changed how you talk to their other parent. They just need the adults to be civil.

How to count “no contact days” when you still talk
A tracker can still help, you just have to define what counts. Many co-parents count a day as “no contact” if every exchange that day was about the children and in the agreed channel. A day breaks the streak if you:
- Sent a message about the relationship, your feelings, or their life.
- Checked their social media or asked about them through someone else.
- Had a handover that turned into a personal conversation you started or kept going.
- Replied to a bait message with emotion instead of facts.
Write your own definition down on day one so you can’t renegotiate it at 11pm. If you slip, don’t throw the whole plan out. Our guide on what to do after you break no contact applies to co-parents too.
When your ex won’t respect the boundary
Some exes keep pushing. They send long emotional messages, call “about the kids” and switch topics, or show up early to talk. A few things help.
- Answer only the child-related part. If a message has one logistical question and four paragraphs of feelings, answer the question. Ignore the rest without comment.
- Delay non-urgent replies. You don’t owe an instant response. A few hours, or the next morning, is fine for anything that isn’t an emergency.
- Get a written parenting plan. The more is decided in advance (weekends, holidays, birthdays, how to swap days), the less you have to negotiate live. In England and Wales, Cafcass publishes a free parenting plan template. In the US, many state court websites have one.
- Consider a mediator if you can’t agree on basics. A neutral third party often lowers the heat.
If you’re dealing with abuse or control
Grey rock and BIFF help with difficult exes. They are not a safety plan for an abusive one. If your ex threatens you, monitors you, or uses the children to control you, talk to a family lawyer and a specialist service. In the US, the National Domestic Violence Hotline is 1-800-799-7233. In the UK, the National Domestic Abuse Helpline is 0808 2000 247. If you are in danger right now, call 911 or 999.

How long until this gets easier?
Honestly, co-parents often take longer to feel detached than people who can cut contact completely, because you keep seeing the person. But the pattern most people describe is that the first month of strict boundaries is hard, and then handovers start feeling like errands instead of events. If you want a sense of what’s normal, our breakup recovery timeline walks through it week by week.
You don’t have to stop caring about your ex to do this well. You just have to stop running your emotional life through the same channel you use to arrange swimming lessons.
FAQ
Can you do no contact if you have a child with your ex?
Not in the strict sense, but you can do modified no contact. You keep communication about the children and cut everything else: personal messages, social media checking, and conversations about the relationship. Most people find this gives them the same emotional break.
What is modified no contact?
Modified no contact means you only communicate with your ex about necessary practical matters, usually children, a shared lease, or work, and keep those exchanges brief, factual, and ideally in writing. Anything personal or emotional is off the table.
How do I respond to my ex’s emotional texts when we co-parent?
Reply only to the part about the kids, using a brief, factual, polite tone, and ignore the emotional content without commenting on it. If there’s nothing about the kids, you don’t need to reply at all unless it’s urgent.
Should I block my ex if we have kids?
Usually not on your main contact channel, because you need to be reachable about the children. You can mute or unfollow them on social media, move logistics into a co-parenting app or email, and keep one emergency phone line open.
Is a co-parenting app worth it?
For many separated parents, yes. Apps like OurFamilyWizard, TalkingParents, and AppClose keep schedules, expenses, and messages in one place and away from your personal texts. In high-conflict situations, the message log can also be useful if you ever need records.
How do I stop talking to my ex at drop-offs?
Have the kids ready before your ex arrives, keep the handover to a couple of minutes, and use a scripted exit line. If personal topics come up, say you’d rather not discuss it in front of the kids and redirect anything practical to writing.
