How to tell THE children you are separating
Telling children you are separating is one of the hardest conversations a parent will face, but how you approach it can make a significant difference to how children cope. Experts agree that children do best when parents are honest, calm, and reassuring, regardless of how difficult the circumstances are. With the right preparation and a child-focused approach, most children adjust well over time.
Knowing how to tell the children you are separating is something most parents dread long before the conversation actually happens. You may be worried about their reaction, unsure how much to say, or concerned about the long-term impact on their wellbeing. All of those feelings are completely understandable.
The good news is that research consistently shows that children are more resilient than we often fear, and that the quality of the conversation, and the child arrangements that follow it, matter far more than the separation itself. In this guide, we cover how to approach the conversation, what to say at every age, common mistakes to avoid, and how family mediation can help reduce the conflict that research shows affects children most.
Before You Have the Conversation
A little preparation goes a long way. This is not a conversation to have on the spur of the moment, or in the middle of an argument. Taking time to plan together, if at all possible, makes a real difference.
Plan Together Where Possible
Ideally, both parents should tell the children together. This demonstrates a united front and sends a powerful message: even though things are changing between you as a couple, you are both still their parents and you are both still there for them. Where this is not possible due to conflict or distance, try to agree broadly on what will be said so children receive consistent messages from both sides.
Prepare Yourself Emotionally
Children take their cues from parents. If you are visibly distressed, it can amplify their anxiety. It is fine to show some emotion, children need to see that feelings are normal, but aim to be as calm as you can. If you are struggling, consider talking things through with a counsellor or a trusted friend before you sit down with your children.
Choose the Right Time and Place
- Choose a quiet, familiar space where children feel safe
- Avoid significant dates such as birthdays, Christmas, or just before school exams
- Make sure there is no time pressure, you want to allow space for questions and reactions
- If one parent is moving out, try to have the conversation before that happens rather than after
- Plan for both parents to be around for a while afterwards where possible
Think About Three Key Messages
Before you sit down with your children, agree on three things you want them to take away from the conversation. For example:
- This is not your fault
- We both still love you and that will never change
- You can ask us anything, at any time
These three messages form the backbone of every conversation you will have with your children about the separation, now and in the months ahead.
What to Say: A Practical Guide
Keep the conversation honest, but age-appropriate. You do not need to share every detail. Avoid blaming the other parent, even if tensions are running high. Children love both of you and putting them in the middle is one of the most harmful things that can happen during a separation.
Some useful phrases to consider:
- “Mummy and Daddy have decided not to live together anymore.” Simple and factual.
- “This is nothing you did. This is a grown-up decision.” Reassures without over-explaining.
- “Daddy will still pick you up from school, but he will be sleeping somewhere else.” Makes the change concrete and manageable.
- “I don’t know the answer to that yet, but I’ll find out and tell you.” Honesty about uncertainty is fine.
- “You can always talk to us about how you’re feeling.” Keeps the door open.
“One of the things we hear most often from parents coming into mediation is that they are worried about the impact of the separation on their children. What we always say is this: the separation itself is rarely the deciding factor in how children cope. What matters most is the level of ongoing conflict they are exposed to. Children who see their parents communicating, even in a limited way, and who are kept out of adult disputes, tend to do remarkably well.”

Telling Children You Are Separating: Age by Age
The way you approach the conversation should change depending on your child’s age and development. What works for a five-year-old will feel dismissive to a fifteen-year-old, and the reverse can be overwhelming for a young child.
Under 5s: Keep It Simple and Physical
Very young children do not need detailed explanations. They need to know that they are loved, that they are safe, and that their routines are not disappearing. Focus on the practical: where they will sleep, who will take them to nursery, when they will see each parent.
- Use very short, simple sentences
- Repeat the conversation in small doses as they process it over time
- Offer physical comfort, cuddles, their favourite toy, familiar surroundings
- Help them name their feelings using physical descriptions: “Does your tummy feel wobbly?” rather than “Are you anxious?”
- Drawing or play can help young children express feelings they do not have words for
A parent’s experience
“My daughter was three when we told her. We kept it very simple, just that Daddy was going to sleep at a new house but would still take her to nursery every morning. She seemed to take it in her stride at first, but for weeks afterwards she would ask at bedtime, ‘Is Daddy coming back?’ We just kept answering calmly and consistently, every single time. A few months on she barely mentions it. The routine was what kept her steady, not the conversation itself.”

Ages 5 to 11: Honest, Practical and Reassuring
Primary school-aged children often understand more than parents expect, but they also tend to internalise blame. It is common for children in this age group to wonder if they caused the separation, or if they could somehow fix it. Be very direct about the fact that this is an adult decision with nothing to do with them.
- Answer questions honestly, but do not volunteer adult details about the reasons for the split
- Describe practical changes from their point of view: “You will have a bedroom at both houses”
- Reassure them that their relationship with both parents is not changing, only the living arrangements
- Keep school, activities and friendships as stable as possible
- Watch for signs of anxiety or withdrawal in the weeks that follow and talk to their teacher if helpful
A parent’s experience
“My son was seven. He listened to us tell him, went quiet for a minute, and then asked if he could still go to football on Saturdays. We said yes, absolutely. He seemed relieved. But about three weeks later he came to me crying and said he thought it was because he had been naughty. That floored me. We had said it wasn’t his fault during the conversation, but he had clearly been carrying that worry around. We had to have the whole thing again. I would tell any parent: say it once, and then say it again. They need to hear it more than you think.”

Teenagers: Open, Honest and Non-Pressuring
Teenagers are dealing with a huge amount already. Their reaction to your separation may be surprising, muted, explosive, or delayed. Try not to read too much into the initial response. What teenagers need most is to feel that you are available when they are ready to talk, without pressure to open up on your timeline.
- Find a neutral setting, a walk, a car journey, somewhere without face-to-face pressure
- Use open questions: “How are you feeling about it all?” rather than “Are you OK?”
- Accept what you hear, even if it is uncomfortable or directed at you
- Do not ask teenagers to take sides or to relay messages between parents
- Agree in advance with the other parent that you will both give the same basic account of what is happening
- Remind your teenager that their feelings toward their other parent are entirely their own, and are not under any obligation to mirror yours
Some teenagers find it easier to talk to someone outside the family. Consider whether a school counsellor, a trusted relative, or an external therapist might help if they are struggling to open up at home.
A parent’s experience
“My fifteen-year-old just said ‘OK’ and went back to her room. I was devastated by that reaction, I had braced myself for tears or anger and got nothing. For a few weeks she was distant and I didn’t push it. Then one evening on the way back from cadets she just started asking questions, practical ones at first and then harder ones. I just answered honestly and tried not to make it a big moment. Looking back, the car was the right place for her. No eye contact, somewhere to look, no pressure. She came to it in her own time.”
Parent, Leeds
A Note from Our Mediators
We recently worked with a couple with children aged 7 and 14. The parents were worried that the age gap meant they needed two completely different conversations. In practice, they found that having both children present at the same time, with the understanding that they could ask different questions, worked well. The older child actually helped explain things to the younger one in the days that followed, which gave her a sense of involvement rather than helplessness. Every family is different, but there is often value in bringing children together rather than separating them for the conversation.
After You Have Told the Children: What Comes Next
The conversation is just the beginning. How you behave in the weeks and months that follow has a significant bearing on how your children adjust. Research consistently shows that the factor most likely to cause lasting harm to children during a parental separation is ongoing, visible conflict between parents, not the separation itself.
Maintain Routine and Stability
Children feel more secure when life is predictable. Keep school, activities and social arrangements as consistent as possible. If there are changes to the usual routine, explain them in advance and frame them positively from the child’s perspective.
Expect to Revisit the Conversation
Children do not process significant news in one sitting. They will come back to it, sometimes weeks or months later, with new questions or feelings. Be open to these conversations whenever they arise, even if the timing feels inconvenient. A question at bedtime or out of the blue in the car is usually a sign that they feel safe enough to ask.
Avoid Using Children as Messengers or Confidants
One of the most damaging things for children during a parental separation is being put in the middle. This includes asking them to pass on messages, questioning them about what the other parent has said or done, or sharing adult worries with them. However well-intentioned, it places an unfair burden on children that they are not equipped to carry.
When Children May Need Additional Support
Most children adjust well in time, but some may benefit from additional support. Signs to look out for include persistent changes in behaviour or mood, withdrawal from friends or activities, a significant drop in school performance, sleep difficulties, or physical symptoms such as stomach aches with no medical cause. Speaking to your GP, their school, or a family therapist can help if you have concerns.

How Family Mediation Helps Children During a Separation
One of the most effective things separating parents can do for their children is to resolve disputes about arrangements quickly and calmly, away from court. Family mediation provides a structured, neutral space where both parents can agree arrangements for the children, covering where they will live, how contact will work, holidays, schooling and more.
Unlike court proceedings, mediation is private, significantly less expensive, and far quicker. Agreements reached in mediation can be set out in a parenting plan, which provides both parents, and the children, with a clear framework going forward. This can also be updated over time as children grow and circumstances change.
Child Inclusive Mediation
Where appropriate, children can be given a voice in the mediation process through Child Inclusive Mediation (CIM). A specialist mediator meets separately with the child, with their agreement, to understand their feelings and wishes. These views are then fed back to the parents as part of the mediation process. It is not about putting children in the middle, but about making sure their voice is heard in a safe and supported way.
What Happens After the MIAM
To start the mediation process, both parents need to attend a Mediation Information and Assessment Meeting (MIAM). This is a short individual appointment with a mediator where you can find out more about how mediation works, whether it is suitable for your situation, and what the next steps look like. If you decide to proceed, joint sessions follow, usually lasting around 90 minutes each.
You can book your MIAM online at a time that suits you, including evenings and weekends. You also attend alone, so there is no pressure to be in the same room as your ex-partner at that stage.
Common Mistakes to Avoid
Even the most well-intentioned parents sometimes handle things in ways that make things harder for their children. The following are some of the most common pitfalls:
- Sharing too much detail: Children do not need to know about affairs, financial disputes or the specifics of what went wrong. Keep the focus on reassurance and practicalities.
- Badmouthing the other parent: Even subtle negative comments can place children in an impossible position. It damages their relationship with the other parent and ultimately damages your relationship with them too.
- Assuming no reaction means no problem: Some children, particularly teenagers, internalise their feelings. A calm or dismissive response to the news does not mean they are fine, it may mean they need more time.
- Making promises you cannot keep: It can be tempting to over-reassure. Only commit to arrangements you are confident you can deliver.
- Telling the children before arrangements are confirmed: Where possible, have at least a broad outline of the immediate practicalities in place before the conversation, so children are not left in uncertainty about where they will be sleeping or when they will see each parent.
- Having the conversation only once: Children need to revisit this over time. Make it clear from the outset that they can always come back to you with questions or feelings.

Myths About Separation and Children
There are a lot of assumptions about what separation means for children. Here is what the research actually shows.
Myth: Staying together for the children is always better
Research shows that where there is ongoing conflict in a relationship, children often fare better after separation. The quality of family relationships matters far more than the structure.
Myth: Children of separated parents do less well
A significant body of research shows that children of separated parents do just as well when conflict is managed and they maintain good relationships with both parents.
Myth: The effects of separation last forever
Most children find the first year hardest. With consistent support and stable parenting, research shows that long-term outcomes are broadly similar between children from separated and intact families.
Summary
Telling your children you are separating is one of the most emotionally demanding things you will do as a parent. But with careful preparation, age-appropriate honesty, and a united approach where possible, children can come through it with their security and confidence intact.
The most important things you can do are to keep communication open, keep conflict away from your children, and focus on maintaining their routines and relationships with both parents. Family mediation can play a significant role in achieving all three, by helping parents agree practical arrangements in a structured, calm environment.
Frequently Asked Questions
What is the best age to tell children about a separation?
There is no ideal age. Children at every stage of development need to be told in an age-appropriate way. The key is not to leave children in uncertainty or to find out from someone else. Tell them as soon as you have a clear enough picture of what is changing to answer their practical questions.
Should both parents be there when telling the children?
Where possible, yes. Having both parents present reinforces the message that you are both still there for them and that the separation is a shared adult decision. If the relationship is too hostile to manage this safely, it is better for one parent to tell the children than to expose them to an argument.
How do I explain separation to a young child?
Keep it short, simple and focused on the practical. Use sentences like “Mummy and Daddy are not going to live together anymore, but we both still love you very much.” Describe what will change from their point of view, such as where they will sleep and who will take them to school. Follow up with cuddles and routine.
My teenager is not reacting at all. Is that normal?
Yes, it is quite common. Teenagers often process significant news internally before they are ready to talk about it. A muted or dismissive response does not mean they are fine, it may mean they need more time or a different setting to open up. Keep the door open, check in regularly, and try neutral settings like a walk or a car journey where direct eye contact is less intense.
Should I tell the children’s school about the separation?
It is generally a good idea to let the school know, in broad terms, that there is a family change. Teachers can then keep an eye on mood and behaviour and provide quiet support if needed. You do not need to share the details, simply letting them know that things are changing at home can make a significant difference.
How can family mediation help our children?
Family mediation helps parents agree practical arrangements for their children, including where they live, how contact works, holidays and schooling, without going to court. Because mediation reduces conflict and speeds up the process of reaching agreements, children benefit from having clarity and stability sooner. Child Inclusive Mediation also gives children a supported voice in the process where appropriate.
What if we cannot agree on child arrangements?
If parents cannot agree on arrangements for their children, the next step is usually family mediation before applying to court. A mediator helps both parents work through their disagreements in a structured way, focusing on what is best for the children. If mediation is not successful, either parent can apply to the court for a Child Arrangements Order.
