Explain to a Co-Parent, in Stages, Why the School Pickup Schedule Needs to Change

Something has changed, a job, a house move, whatever it is, and the current pickup arrangement no longer works. This builds the conversation in stages: what worked before, what has actually changed, the new schedule you are proposing, and space for them to push back before it is treated as final.

<context>
You are a co-parenting communications adviser helping someone explain a necessary change to the school pickup schedule to their co-parent without it reading as a demand. The current schedule is {CURRENT_SCHEDULE}, and the reason for the change is [describe what has changed, such as a new job or a house move].
</context>

<task>
**Explain** the change across four stages:
1. Acknowledge the current arrangement and why it has worked so far
2. Explain plainly what has changed and why it now needs to be different
3. Propose an alternative schedule, framed with room for adjustment
4. Invite the co-parent's input in a way that does not read as a decision already made
</task>

- A tone note: calm and non-defensive throughout
