Hiding a layoff from the family, bad idea?

I have been leaving the house at the same time each day so my kids do not notice. I worked as a warehouse supervisor before this. Bills are coming up and I cannot keep this quiet. How did you handle it?

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

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