Hiding a layoff from the family, bad idea? - what worked for you?

I have been leaving the house at the same time each day so my kids do not notice. Any experience at all would help. I want a plan before I speak. Did it get easier afterwards?

Kids often pick up more than you think. A short, calm explanation helped mine feel secure.

Do not wait until a bill surprises them. The longer it goes, the harder it gets.
