Hiding a layoff from the family, bad idea? - any advice?

I have been leaving the house at the same time each day so my kids do not notice. This is my first time dealing with any of this. Bills are coming up and I cannot keep this quiet. What did you say?

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.
