Most emergency-prep advice is written for one adult living alone. This is the version for a house with a child in it - or a child and an aging parent, or a baby, or all three.
The official checklists linked throughout this guide are thorough and free, and we point to them rather than rewriting them. What they do not cover is the part specific to a family with children: what goes on a child's own list, how to talk to them about it, and what changes when someone in the house needs more help than a standard list assumes.
What goes on their list, what stays on yours.
What to put on it, and why a memorised number is not enough.
The paperwork nobody thinks about until it is underwater.
Why to watch behaviour, since a baby cannot tell you.
How to make it one plan instead of two.
How to make planning an ordinary task, not a worst-case talk.
