When a family changes

Co-parenting

Two keys, one home.

These pages are about raising a child with another adult: a partner, a former partner or a step-parent, sometimes across two cultures. They’re for the small disagreements that turn into big ones, and for the stability a child needs from both of you.

What to do first and who else can help are free to read and to print.

What the library holds on co-parenting

For a child aged

From the therapists

What to do first

You don’t have to like each other, or agree, to co-parent well, but you do have to be predictable. Children can manage two different households. What they struggle with is two households at war.

  1. Take the logistics off your child. Use a shared calendar or a written handover message, so they’re never the one passing information between you.
  2. Pick the two rules that will be the same in both homes, and let the rest differ. Trying to match everything is how co-parenting fails.
  3. When you’re stuck, take it to a mediator or a solicitor, not to your child. The Family Mediation Council lists accredited mediators by area.

Short pieces for the moment in front of you, each with things to try.

Family transitions

Telling the Children About the Separation

A child usually remembers the second conversation about a separation, when they ask what’s been on their mind.

Try this

  • Have the conversation together, in one room, calmly and briefly.

Family transitions

The Diary Across Two Houses

A child living between two homes has a lot to keep track of, so give them a shared diary.

Try this

  • Print a colour-coded week on the fridge at your child’s eye level.

Family transitions

The Handover at the Door

Keep the handover at the door short and factual, and have the adult conversations somewhere else.

Try this

  • Keep the doorway exchange to the practical facts and goodbye.

    Your Child’s Side of the Handover

    The moments either side of a handover are easier when your child’s things are already in both homes, the goodbye is predictable, and no questions are asked the minute they walk in.

Things to do together

2 on co-parenting

Small, repeatable things to do with your child, with what to watch for and when to get help.

To do together · About 20 min

Both homes, one calendar

Both parents keep one calendar up to date, and your teenager adds their own plans to it. Once a term, each of you asks them how the arrangements are working.

What it is for. Teenagers living across two homes often say they want a say in the arrangements, and don’t want to be the go-between. A calendar the adults keep accurate, which your teenager can see and add to, gives them a voice without putting them in the middle.

  1. The first step Agree between the adults which calendar you will use and who updates what. Do this without your teenager.

Safety. Where there has been domestic abuse, or an address needs to stay private, don’t use a shared calendar or location sharing that could show where your teenager or you are. You don’t have to agree changes with the other parent directly; get advice on a safe way to do it.

When to get help. If your teenager seems low for several weeks, withdraws, their schoolwork falls away or they start taking risks, talk to your GP and their school. If your teenager tells you they are frightened to go to one home, or that someone is hurting them, that they are hurting themselves, or that they don’t want to be alive, stay calm, thank them for telling you, don’t promise to keep it secret, and act that day, using the routes under “If you need help right now”, at the foot of every page. If the person hurting your child lives in your home or your child’s other home, go straight to children’s social care or the police.

The other four steps, and your part in it, are in the library.

Who else can help

The route that helps most here is usually the one that lowers the conflict, not the one that treats the child. Mediation first.

Where to start

  • A family mediator

    Mediators help two parents reach their own arrangements about children and money, without going to court. In most cases you have to attend a first meeting about mediation before a court will hear you.

    Early, and before positions harden. The Family Mediation Council lists accredited mediators by area.

    www.familymediationcouncil.org.uk

  • Your child’s school

    The pastoral lead, the head of year, or the form tutor. Free, already knows your child, and often the quickest way to get something changed at school.

    Before or alongside anything else. A school cannot act on what it has not been told, and what you bring is often what it did not have.

  • Citizens Advice

    Free, independent advice on the practical layer: housing, benefits, debt, employment, and your rights when a family separates.

    When the worry is partly a practical problem wearing an emotional coat. Solving the practical part often lowers the temperature at home more than anything else will.

    www.citizensadvice.org.uk

  • Private therapy, if you can meet the cost

    A registered counsellor or psychotherapist, found through the BACP or NCPS directories. Waiting lists are shorter than the NHS and you choose who your child sits with.

    When waiting is the problem, or when you want a particular kind of help. What to look for, and what to expect, is set out in our guide to finding a therapist.

For co-parenting

  • Cafcass (for separating parents)

    The official body that advises the family courts about children. A free parenting plan you can fill in together, plain factsheets on what happens if you go to court, and a course on parenting apart.

    Early, before positions harden. The parenting plan is worth doing whether or not a court is ever involved.

    www.cafcass.gov.uk/parent-carer-or-family-member

  • Resolution

    The body for family lawyers and mediators who sign up to a non-confrontational code. Free guides on separating with children, and a directory to find a member near you.

    When you need a lawyer or mediator and want one committed to keeping the temperature down. The guides are free; the professionals are not.
