Start with needs rather than names
Divide a page into everyday tasks, unexpected situations and moments when you need someone to talk to. Add one example under each heading: receiving groceries, a person to call when care arrangements change, or a short conversation after a difficult day. One person does not need to cover every kind of support.
Check availability together
Ask potential helpers what support they can offer and when. Do not list someone as a backup caregiver without their agreement. Check current arrangements directly with local family centres and libraries. Treat the map as a starting point you can update rather than a fixed contract.
Your next little step
Choose one idea that suits your family and try it at your own pace. Every family has different needs.
