You're in a good spot.

1) Talk to your wife, make sure she knows that layoffs happened at your company and that you were not affected this time round.

2) Calculate your monthly expenses

3) Work out your exact runway. How many months can you go without working.

If you want a longer runway then reduce your expenses.

Personally I felt completely secure when I bought my house outright, no mortgage. Everything up till that point was just incremental improvements.
