Nothing makes finances more 'in your face' than the reality of a new little one! We've gone from two incomes that let us pay bills and have fun to one income that makes it if I watch it.
My advice would be to try to work things out so that you could make it work with you part time or at home for the first year of your babe's life. After your baby can eat solids and be with someone else for awhile it's easier to go back to work... now that dd is 2, I think I would be okay working full time, if I needed to. It gets easier when they are older.
I went back to work after dd #1 and it just wasn't worth it- too hard logistically to be away from my infant. Then I picked up part time work that I could do with her and then by 18 months or so she started staying with a sitter so I could work- but by then it was just me choosing to have some 'quiet time' (my employer accepts dd as part of the package)- and I got a raise that allowed me to afford a sitter.
So even if your $$ is tight right now, you'll be able to make it work. New babies really need their mom's attention (IMO!); I know that now for this go-round. When they are a little older, you could go back to work if you needed to.
But anywhoo, didn't mean to make you

PS: During the first 6 months of my dd's life my car went 'kaplooy', several times, in horrible locations. My dh and I ended up sharing his truck for months until my dad came to fix my car- I finally realized I needed help when my dh ended up not working for a month (was it two?) due to severe back pain. I had 1. an infant 2. an immobile drugged partner and 3. one standard cab gas-guzzling pick up. Yes, it was a rough time.
