Ex Undermining Your Parenting

Family & Parenting Clinical Reviewer Updated June 19, 2026 2 cited sources

Co-parenting conflict happens when a former partner actively undermines your parenting, dismissing your rules, criticizing you to the children, or rewarding behavior you discipline. It is disruptive for children and exhausting for you, and there are concrete steps that can help. If you are in this situation, you are probably not imagining it, and you are not powerless.

Key takeaways

  • Documentation matters: recording specific incidents with dates and details protects you legally and helps you see patterns clearly over time.
  • Co-parenting conflict harms children most when it pulls them into the middle — your consistency at home is one of the most stabilizing things you can offer them.
  • Written communication through a co-parenting app or email creates a factual, low-conflict record and reduces the chance of heated exchanges being misrepresented.
  • Mediation or co-parenting counseling can shift dynamics that direct conversation cannot — a neutral third party changes what is possible.
  • If undermining behavior violates a custody agreement, an attorney can clarify your options; you do not have to tolerate what is legally actionable.

What you might be experiencing

Co-parenting conflict of this kind rarely looks dramatic from the outside, which can make it harder to name. Your ex may tell your children that your rules do not apply at their house, openly criticize your decisions in front of them, or undo discipline you have put in place — offering rewards right after a consequence you set. Over time, your children may start testing your boundaries more, or repeat things that sound like your ex's words coming out of their mouths. That is not a sign you are failing. It is a sign they are navigating a confusing situation.

The emotional weight of this is real. Being undermined as a parent can feel like a slow erosion — of your authority, your confidence, and your relationship with your children. You may find yourself second-guessing your own reasonable rules, or dreading what your children will come home saying after a visit. That exhaustion is a normal response to an abnormal dynamic, not a reflection of your parenting.

What can help

There are practical steps you can take starting now, without waiting for your ex to change. Document specific incidents — what was said or done, when, and what your child reported — using a notes app, a dedicated email to yourself, or a co-parenting platform like OurFamilyWizard or TalkingParents. Written records serve two purposes: they help you recognize patterns, and they become evidence if the situation ever requires legal intervention.

For communication with your ex, shifting to written-only exchanges through a co-parenting app or email keeps conversations factual and child-focused. It also removes the emotional charge that phone calls and in-person conversations can carry. When you speak with your children about differences between households, explain your own rules calmly without criticizing their other parent — something like "in our home, we do it this way" gives children a framework without putting them in the middle.

For recurring patterns, co-parenting counseling or family mediation can help in ways that direct conversation between you and your ex often cannot. A neutral professional changes the dynamic. If the behavior crosses into what your custody agreement prohibits — or rises to the level of parental alienation — a family law attorney can clarify what your agreement actually covers and what remedies exist. This is not an overreaction. It is using the systems that exist for exactly this situation.

When to reach out

Asking for support with co-parenting conflict is not a sign that things have reached a crisis — it is a sign that you are taking your children's wellbeing seriously. A therapist who works with separated or divorced families can help you develop strategies, process the emotional toll, and decide when escalation to legal or formal channels makes sense. You do not need to wait until things get worse to make that call.

Reach out to a professional sooner rather than later if your children are showing signs of distress — anxiety, withdrawal, declining school performance, or expressing that they feel caught between their parents. These are signs the conflict is affecting them in ways that benefit from professional support, whether through family therapy, play therapy for younger children, or your own individual therapy to help you respond from a steady place.

If the situation involves any threat to your children's physical safety, or if you are experiencing thoughts of self-harm under the weight of this stress, please do not wait. If you are in the US and need immediate support, you can call or text 988 (Suicide & Crisis Lifeline) at any time.
