Common Co-Parenting Mistakes and How to Avoid Them

Key Points

One mistake outranks all the others: putting your child in the middle. A meta-analysis of 49 studies covering more than 23,000 people found a moderate association between parental conflict and children feeling caught between their parents. Feeling caught is the mechanism by which conflict reaches your child.

You do not have to like each other for this to work. Cooperative co-parenting is one model, not the only one. Businesslike, low-contact parenting works too, and for high-conflict families it usually works better than forcing a friendliness neither parent feels.

Being close to both parents protects your child. In the landmark study on this, adolescents who were close to both parents reported feeling caught far less often. Supporting your child's relationship with your co-parent is not generosity toward your ex. It is protection for your child.

Small order violations do the most quiet damage. Chronic lateness and unilateral schedule changes rarely produce a single dramatic consequence. They produce a documented pattern, and patterns are what judges respond to.

Good intentions are not a system. After ten years of teaching this seminar, the difference I see between families who do well and families who return to court is rarely attitude. It is whether they left with a calendar, a channel, and a written process.

For the past decade I have taught the court-approved parent education seminar in Virginia as a vendor approved through the Office of the Executive Secretary of the Supreme Court of Virginia. Under Virginia Code § 16.1-278.15, parents in contested custody, visitation, or support cases have to show proof they attended an approved seminar, either within the twelve months before their court appearance or within forty-five days after. Minimum four hours. Most states have some version of this requirement, so if you have a case pending, check yours.

What that means is that I meet parents at a very specific moment. After the filing. Before the resolution. Usually angry, often frightened, and almost always convinced that the problem is entirely on the other side of the room.

Thousands of parents later, the mistakes are remarkably consistent. Here are the seven I see most, ordered by how much damage they do rather than by how obvious they are.

1. Putting Your Child in the Middle

This is the one. If you fix nothing else on this list, fix this.

It looks like a dozen small things. Sending a message through your child. Asking what happened at the other house. Reacting visibly when they tell you. Venting on the phone where they can hear. Asking, even gently, which house they'd rather be at.

The research on this is unusually clear. In a landmark study, Buchanan, Maccoby, and Dornbusch interviewed 522 adolescents about four and a half years after their parents separated and found that feeling caught between parents was tied to high parental conflict and hostility and to low parental cooperation. A 2026 meta-analysis in Human Communication Research pooled 49 studies covering 23,336 individuals from more than 15,000 families and found a moderate positive association between interparental conflict and children feeling caught.

Here is what I emphasize in every seminar: conflict does not reach your child directly. It reaches them through this. Two parents can disagree substantially and, if they keep the child out of it, the child does fine.

And from that same 1991 study, the part nobody quotes: adolescents who were close to both parents reported feeling caught far less often. Your child's relationship with the other parent is not competition. It is a buffer.

The test I give parents. Before you say it, ask whether you are giving your child information or giving them a job. "Dad's picking you up at five" is information. "Ask your dad why he's late again" is a job.

2. Disparaging the Other Parent

Related to the first, but distinct enough to name separately, because the version I see most is not name-calling.

It's the sigh. The eye-roll when their name comes up. "Well, that's your father." The pointed silence after your child mentions something good that happened at the other house. Children read tone long before they parse words, and a seven-year-old will register your face in half a second.

Here is why it costs you rather than your ex. Your child is half that person. When you tell a child their parent is worthless, the child does not hear a fact about their parent. They hear a fact about themselves.

I get asked about the exception constantly, so let me address it. If there is a genuine safety concern, meaning abuse, substance use, or violence, that belongs with your attorney, documented in facts, not delivered to your child as characterization. Describing behavior you observed is different from telling your child what kind of person their parent is.

3. Violating the Order, Including in Small Ways

Most parents picture violation as something dramatic. In practice it is almost always small and repeated.

Fifteen minutes late, most weeks. Changing the schedule without asking and telling your co-parent after. Not passing along the school notice. Signing the child up for a Saturday activity that quietly eats into the other parent's time.

Two things happen. The first is legal: none of these produces a single dramatic consequence, but all of them get logged, and a pattern is exactly what a judge responds to. The second is practical and it is the one parents underestimate. Every small violation spends trust you are going to need later, when you want a swap for a family wedding and your co-parent has no reason to say yes.

One observation from the seminar room that surprises people: the majority of parents in front of me cannot accurately describe their own order. Read yours. Then read it again in six months. If something in it isn't working, the answer is to modify it, not to quietly ignore it.

4. Trying to Co-Parent Like a Couple When You Can't

This is the mistake the standard advice creates, and I want to be direct about it.

Parents are told to be friendly, communicate openly, present a united front, attend the school concert together. That is cooperative co-parenting, and when both people can do it, it's lovely.

For a lot of families it is the wrong target, and chasing it manufactures the conflict it was supposed to prevent. Every attempted joint decision becomes an argument. Every friendly gesture gets misread. Both parents end up feeling like failures at something that was never going to work with the two people involved.

The alternative is businesslike, low-contact parenting. Each household runs itself. Communication is limited to essential logistics, in writing, on a predictable rhythm. The parenting plan is written with enough specificity that there is very little left to negotiate: exchange times to the minute, locations named, holidays assigned years out, decision authority spelled out.

Parents hear that and think it sounds cold. What it is, is quiet. And a child raised in two calm separate households does better than a child raised in one continuously contested arrangement. If cooperative co-parenting isn't working after a real attempt, this isn't giving up. It's choosing the model that fits.

5. Communicating Like You're Still Married

The standard I teach is simple. Before you send it, ask whether you'd send it to a co-worker you don't particularly like but have to finish a project with.

That produces messages that are brief, informative, friendly, and firm. It also strips out the history, the score-keeping, the "as I've told you a hundred times," and the bait.

What people send: "Once again you couldn't be bothered to tell me about the parent-teacher conference. This is the third time and it's obvious you're doing it on purpose. If you can't manage basic communication I don't know how you expect to have any say in her education."

What works: "I wasn't aware of the conference on the 14th. Going forward, can we both forward school emails to each other within 24 hours? I'll do the same on my end."

The second one is shorter, has no adjectives, proposes a fix, and would look excellent to anyone who reads it later. It also gives your co-parent nothing to fight with, which is the point.

Two rules on timing. Nothing important gets sent after nine at night. And when you're angry, write the whole message, save it, and send nothing. I have never once had a parent tell me they regretted not sending it.

6. Competing

Co-parenting turns competitive almost on its own, and it takes forms people don't recognize as competition.

The gift escalation. Becoming the fun parent because you have less time and want it to count. Loosening rules your household used to have. And the subtle one: asking about their weekend while actually fishing for evidence that they had a worse time over there.

It fails for a straightforward reason. Children do not measure love in outings, and what they need most during this period is exactly what competition erodes: predictable bedtimes, consistent expectations, and adults who are not auditioning.

If you want to win, and every parent does, here is what winning looks like. Being the house where the routine holds. Being reachable. Being the parent who never puts them in the middle. Twenty years from now that is what they will describe, and they will not remember who bought the better birthday present.

7. Not Building a System

This is the mistake nobody names, and after ten years I think it is the one that actually separates outcomes.

Everything above fails less from bad intent than from no infrastructure. Parents leave my seminar sincerely wanting to do better, go home to a hard week, and default to whatever they did before.

A system means five specific things. A shared calendar both parents can see. A single written communication channel, so nothing lives in three places. A written process for decisions that says what requires agreement, what doesn't, and how long the other parent has to respond. A standing time to handle logistics, so they don't erupt at exchanges. And a plan for belongings, medications, and homework moving between houses, with a duplicate set of the essentials at each home so a forgotten inhaler is not a crisis.

None of that is emotional work. That's why it holds up on the bad weeks, which is the only time it matters.

The seminar is four hours. The habits take years. What I can tell you from a decade of watching parents come through that room is that the ones who leave with a plan tend not to come back. The ones who leave with good intentions often do.

Frequently Asked Questions

What is the biggest co-parenting mistake? Putting your child in the middle. That includes using them as a messenger, questioning them about the other household, and reacting visibly to what they report. A meta-analysis of 49 studies and more than 23,000 people found a moderate association between parental conflict and children feeling caught between parents. Two parents can disagree considerably without harming a child, as long as the child stays out of it.

Are parenting classes required for divorce or custody cases? In many states, yes. Virginia Code § 16.1-278.15 requires parties in contested custody, visitation, or support cases to show proof of attending an approved four-hour seminar, either within twelve months before their court appearance or within forty-five days after. Virginia caps the fee at $50 on a sliding scale. Requirements vary widely, so check your state and your specific court. Virginia's court system maintains a directory of approved seminars.

What if my co-parent keeps violating the custody order? Document it factually with dates and times, keep your own compliance clean, and take the pattern to your attorney. Do not retaliate by withholding time, because that makes you a violator too and it costs your child. One late pickup is a bad day. A documented six-month pattern is something a court can act on.

Do my co-parent and I have to get along? No. Cooperative co-parenting works when both people can manage it. When they can't, businesslike parallel parenting, with each household running independently and communication limited to logistics in writing, generally produces less conflict and better outcomes for children than forcing a cooperation neither parent feels.

How should I communicate with a difficult co-parent? In writing, briefly, the way you'd write to a colleague you don't like but have to work with. State what's happening, what you need, and by when. No history, no adjectives, no responding to bait. Nothing important after nine at night, and when you're angry, write it and don't send it.

Can I tell my kids the truth about why we divorced? Age-appropriate information about what is changing, yes. Characterization of their other parent, no. Children experience criticism of a parent as criticism of themselves, since they are half that person. If your concern involves genuine safety, that belongs with your attorney as documented fact, not with your child as opinion.
