I want to have a baby, but I’m scared

I want to have another baby. My two other kids are 7 and 9. I’m getting older. My brain is giving me so many reasons why this is a bad idea. I’m worried about money. We are in the middle of getting a new company running. I feel like I should have done it years ago if I was going to to it. My family relies on me for so much. If I am not feeling well, I don’t know how they will cope without my support. I’m not sure the stress will make it worth it?

My husband and I keep flip-flopping back and forth on this decision. It’s not a decision I can try out. If we do this, it’s a big commitment. How do I decide?
