Just skimmed the last posts about nursing, but from my perspective, it's a great option. The pay ranges that Fuego posted are about right. If you work in a critical care, you can probably get to around 100k/year with shift differentials, overtime, etc. A lot of schedule flexibility, which is great when you have kids. And I tend to think you'd always find work.
Also, you may not need a BSN. My SO has a two year degree and has no pressure to get a BSN and where she works. Plus, there's no difference in pay between 2 year degree or BSN.
I know that some schools offer a nursing path if you have a bachelor's in a different major. I think it might be for a master's in nursing. You'd still have to do all the prerequisites, but it could be a quicker path and you'd have a master's degree.
I also agree with Ha regarding other niche fields. I think anything healthcare has good job prospects (but check before you commit) and many of them require a two year degree and then state licensing. The only risk is to make sure your area doesn't have too many people in the field you choose.
