Dealing with an Ex Who Won’t Discipline the Children

How to Navigate Parenting Inconsistencies with Respect and Focus

Co-parenting after divorce or separation is never simple—and it becomes even more challenging when one parent doesn’t follow through on discipline. Consistency in parenting is crucial for a child’s emotional and behavioral development, and when discipline styles conflict, it can create confusion, frustration, and tension—for you and your child.

If your ex avoids discipline or undermines your efforts, here are constructive strategies that can help:

1. Have a Calm, Productive Conversation

Start by speaking with your ex in a respectful, non-confrontational way. Use “I” statements to express how inconsistent discipline is affecting your child and your co-parenting relationship. For example:

“I’ve noticed that when we don’t enforce the same rules, it confuses the kids and makes it harder for them to know what’s expected.”

Focus on the children’s well-being—not blame or past grievances. Your goal is to open a conversation, not start a conflict.

2. Define Shared Parenting Goals

Discuss what you both want for your children long-term: respect, responsibility, confidence, emotional stability. Aligning on these shared goals can help you work as a team and set consistent expectations, even if you’re no longer living under the same roof.

3. Offer Education—Without Judgment

Sometimes a lack of discipline stems from uncertainty or inexperience. If your ex is unsure how to handle certain behaviors, consider sharing neutral resources—books, parenting websites, or online classes—that promote positive and age-appropriate discipline techniques. You can frame it as:

“I found this really helpful in understanding how to handle tantrums—thought you might like it too.”

4. Model the Behavior You Want to See

Continue enforcing consistent rules and boundaries in your own household. Be calm, fair, and predictable in how you respond to misbehavior. Over time, your example may influence your ex—or at the very least, create a reliable environment for your child when they’re with you.

5. Create a Co-Parenting Agreement

If possible, work together to create a written parenting plan that includes:

  • Household rules and expectations
  • Agreed-upon consequences for rule-breaking
  • How each of you will handle communication and follow-through

Putting your agreements in writing can help avoid misunderstandings and reinforce consistency.

6. Seek Support from a Neutral Professional

When conversations stall or tensions rise, a third party—such as a mediator, therapist, or co-parenting coach—can help. These professionals specialize in conflict resolution and can facilitate a more productive discussion that keeps the focus on your child’s well-being.

7. Set Clear Boundaries

If your ex isn’t willing to collaborate on discipline, you still have control over how things are handled in your home. Communicate your expectations clearly, and if needed, set boundaries about what behaviors you won’t tolerate and how you’ll respond if they continue.

8. Prioritize the Child’s Needs

Remind your ex (and yourself) that this is about your child, not your past relationship. Consistent discipline helps children feel safe, understand consequences, and build life skills. Keep returning the conversation to what’s best for your child’s development—not who’s “right” or “wrong.”

9. Consider Legal Options if Necessary

If your ex’s lack of discipline leads to unsafe or disruptive behavior that affects your child’s well-being, it may be time to speak with a family law attorney. Legal intervention is a last resort—but it can provide clarity and protection in high-conflict situations.

10. Be Patient—and Stay the Course

Parenting consistency may take time to establish, especially after a separation. While you can’t control what happens in the other parent’s home, you can control your approach. Stay calm, consistent, and focused. Children benefit greatly from having at least one steady, dependable parent.
