What to Do if You’re Worried Your Ex Is Alienating You From Your Child

If you feel your relationship with your child is being slowly undermined, the fear can be overwhelming. You may notice your child pulling away, repeating negative things about you, or seeming distant after time with the other parent.

Worrying about alienation does not mean you are paranoid or vindictive. It means you are paying attention to your child and to changes that matter.

What helps most is staying grounded, focused on your child, and clear about what is within your control.

What alienating behaviour can look like

Alienation is not one dramatic act. It is often a pattern of small, repeated behaviours that place pressure on a child’s loyalty.

This can include bad-mouthing you directly or indirectly, sharing adult opinions about you, or framing you as unsafe, uncaring, or the cause of problems.

It can also include undermining your parenting by having far fewer rules, over-indulging, or positioning the other home as the “fun” or “free” one while yours is framed as strict or unreasonable.

Some parents notice their ex interfering with contact, discouraging calls, or creating emotional consequences when the child enjoys time with you.

None of these behaviours are your fault. They also put children under emotional strain, even when they appear to go along with them.

What not to do, even though it’s tempting

When you feel threatened as a parent, it is natural to want to correct the narrative.

Arguing your case to your child, criticising the other parent, or trying to “set the record straight” often backfires. Children may feel caught in the middle or pressured to choose sides.

Avoid interrogating your child about what happens in the other home. This can increase their anxiety and sense of responsibility.

Resist the urge to compete. Trying to match spoiling, bending rules, or winning favour usually undermines your own steadiness.

What actually helps your child

What consistently helps children in these situations is not persuasion, but experience.

Children need structure, predictability, and emotional regulation. These create safety, even if they cannot articulate it yet.

Clear routines, calm transitions, and consistent expectations help your child’s nervous system settle. Being emotionally available, listening without judgement, and staying regulated during difficult moments matters more than saying the “right” thing.

When communication is needed, keep it simple and child-centred. You do not need to defend yourself or explain adult dynamics.

Your steadiness is the message.

Time is the strongest antidote to alienation

The most powerful protection against alienation is time spent together.

Not extravagant experiences. Not constant reassurance. Just reliable, attuned time.

When a child has repeated experiences of being seen, understood, and emotionally safe with you, that reality holds weight. It cannot be erased by someone else’s words.

Quality time looks like presence. Shared routines. Small moments of connection. Letting your child be themselves with you, without pressure to perform loyalty.

Children build their understanding of relationships from what they live, not what they are told.

Protecting your role means protecting yourself too

If your ex is interfering, it is essential to contain how much that interference reaches into your life.

Clear communication boundaries, limited engagement, and support for your own trauma recovery all matter. When your nervous system is constantly dysregulated by your ex, it becomes harder to stay emotionally available to your child.

Looking after your own recovery is not separate from protecting your relationship with your child. It supports it.

The steadier you are, the safer your child feels with you.

A grounded reassurance

Alienation fears can make parents feel panicked and powerless. But children are not as easily turned as it can feel in the moment.

Your relationship with your child is built over time, through consistency, care, and presence.

Focus on what you can control. Your home. Your responses. Your availability. Your healing.

Time, safety, and connection matter more than narratives.

And you do not have to fight to remain your child’s parent. You already are.

When worries about alienation need outside help

It is important to know that deliberately undermining a child’s relationship with their other parent is not acceptable and can be taken seriously by professionals and the courts. In the UK, behaviour that intentionally damages a child’s relationship with a parent can be considered harmful and may have legal consequences.

If your concerns continue despite your best efforts, it may be time to seek external support. Signs that this is needed can include contact being repeatedly blocked or disrupted, your child expressing fear or hostility that does not reflect their lived experience with you, pressure on your child to reject you, or professionals beginning to raise concerns about the child being caught in the middle.

At this point, keeping careful records, seeking specialist legal or therapeutic advice, and accessing trauma-informed support can help you respond in a way that protects both you and your child. You do not need to prove anything on your own or carry this fear in isolation.

If your attempts to stay child-focused and steady are not enough, that does not mean you have failed. It means the situation may now require support beyond co-parenting strategies alone.
