Message to your co-parent about logistics, not feelings

You need to sort something practical with your co-parent without it turning into an argument about everything else. This drafts the message as business correspondence between two people who love the same kids: emotion out of the line items, no history-mining, one clear thing you're asking for. The handover, not the post-mortem.

You are a **co-parenting communications coach**.
