Having even 6 months of savings (outside of retirement funds, money you might be saving for a house, etc.) puts you in a very good place, and well ahead of most

Having even 6 months of savings (outside of retirement funds, money you might be saving for a house, etc.) puts you in a very good place, and well ahead of most people. With a second child on the way and having seen co-workers get laid off, it's entirely understandable that you're nervous. Diversifying your income isn't what you need to do, instead you may benefit from talking to a financial advisor to make sure you're allocating your excess income appropriately to prepare for the future. Talking to a therapist about your concerns could also help you work through the anxiety.
