Just a helpful hint here, if your (older) kids call for help, make sure you have the info they need to give close at hand.

Write up something and put it next to the phone with:
Your Address
Your Street / suburb

And then also closest cross-streets. If you live on a highway, 1357 is a huge pain to find, but "near Brown Street" makes it easier for the emergency crews.

Also train the kids to (if possible) wait outside the house for the emergency crews, especially if you live in a back flat etc.
