Hi, Lisa. Welcome.
A lot of us are embarking on second, or even third careers, and have kids, so we know how you're feeling.
As far as finance, the school financial aid office is helpful. Also, check into your state. Maryland offers grants for up to 3k a year for any full-time nursing student, as long as you agree to work in the state for every semester you use money. Not bad, if you don't plan to go anywhere. You have to pay it back, otherwise. It is not needs based, which is good for middle of the road people-not rich, not poor.
Also, if you and your husband belong to a credit union, you might get a great deal on a low interest student loan. Sometimes they're lower rates than the government loans.
Check with Fastweb.com. You enter info and they come up with scholarships
and grants. It's free, and though I didn't find it terribly helpful, they did list a lot of scholarships I would never have thought of-like grants and scholaships based on hobbies, associations and where you went to high school.
