How do I respond to a hostile co-parent text?

Your reply is not a place to prove every point.

Your reply is a record. Write it like someone calm may read it later.

Try this: acknowledge the topic, give the needed answer, and stop.

Example: I can pick up at 5:30 at the usual place. Please let me know if that changes.

If the message includes blame, name-calling, or old fights, leave those parts alone.

Reply to schedules, child needs, documents, money details, or safety details that need a clear answer.

It is okay to slow down.

You can write: I saw your message. I will review the schedule and reply by tonight.
