Hiding a layoff from the family, bad idea? (update)

My spouse does not know yet that I was let go as an accountant. I have been trying to stay organised about it. I feel ashamed even though the company cut a whole team. How did you handle it?

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.
