mncz - I also agree that you sound as if you would be a capable and self-aware mother. It is especially nice to hear that you are financially capable, and able to spend a lot of time with the baby.
My question is: do you have a support network? Your family, friends, etc. People who would help you out with babysitting, or emotional support. I believe this is very important for your own mental health.
Also - do you have excellent health insurance? This is vitally important when children are involved.
