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

I was laid off 7 weeks ago and have not told my family because I do not want them to worry. I have read a lot of threads here and could not find my exact situation. I want a plan before I speak. 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.
