Q. My daughter’s father has just been diagnosed with an aggressive form of prostate cancer. He will be having chemo and we suspect he will be tired and unable to share her time like he does now. What are some ways I can help? I offered to take her for a while, but he thinks I’m trying to use his illness to get custody. What’s good ex-etiquette?

Answer: Lead with empathy.

A serious diagnosis changes everything overnight. Your co-parent is managing treatment, uncertainty and the very real fear of how this will affect his relationship with his daughter. When time with her feels threatened, even well-meaning offers can land the wrong way.

Good ex-etiquette means supporting his role as her father while helping him through a time when he may not be able to parent in the same way. So shift the approach. Instead of offering to take over, offer to support his time with her.

You might say, “I know this is a lot. I want to support you in whatever way helps you stay connected with her. If you need me to adjust schedules, help with transportation, or give you flexibility, I’m here.”

That keeps him in the parent role and removes the fear that you’re stepping in to replace him.

Think in terms of flexibility, not permanence. Temporary adjustments feel safer than open-ended changes. Shorter visits, quieter activities or time together that allows him to rest while still being present can make a big difference.

You can also support from the outside. Prepare your daughter gently for what she may see — fatigue, changes in appearance, emotional ups and downs — so she’s not frightened or confused. Keep communication open without putting her in the middle.

Be mindful of language. Avoid anything that sounds like you’re “taking” time. Frame everything as helping him maintain his relationship with her during treatment.

If trust is fragile, clarity helps. Let him know your intention: “I’m not trying to change anything long term. I want to make this easier for you and keep things as stable as possible for her.”

This is a moment where co-parenting becomes something more. It’s about showing your child what support, respect and compassion look like when life gets hard.

Protect his role. Offer help without taking over. Stay flexible and clear. You're doing it for your daughter, and because it's the right thing to do. That’s good ex-etiquette.
