Good for you for deciding to do this! This is the perfect timeline for getting started for next fall. I have returned to school a couple times for my BSN and MSN. I have taught in a LPN program. I will give you the same advice that someone gave me: SHOP. You are a highly motivated adult learner. You are a desirable student in any school of nursing. They should show you what they can do for you. Check out the Ohio State Board of Nursing - they should have a list of nursing programs - look for program choices. Look for NCLEX pass rates, you want a program that is >90%. Research the internet for what you can find out but all schools, but then make an appointment with your top 3 choices. You want them to give you a program list of the classes you will need to take, the time it will take, suggested schedule (how many days a week) and cost. Then compare the program for the best fit for you. So many programs offer on-line courses which give a lot of flexibility, but that may not be comfortable for you if you aren't computer savy. (You posted this question, so I am guessing you are pretty good).
Financial aide: Do you work in a hospital now? Check with your employer re tuition reimbursement and scholarships. That's free money with a work commitment after graduation. Typically, 2 years. The school's financial aide office can also help. Do not rule out private colleges - they typically have a lot of money to give. I would suggest you to avoid for-profit schools like Kaplan and University of Phoenix. They are very expensive with high pressure recruiting and at least in Indiana, they have a hard time getting clinical time at hospitals.
I work with a couple LPN's that went back to school at that Regents College of NY, which is now called Excelsior: http://www.excelsior.edu/school-of-nursing. They both found it user friendly.
I am an OB nurse for almost 30 years. Typically, you do have to be a RN to work in L/D. Why not consider "going for it" and finding a RN associate degree program? You will be done in 2 years and you only have to pay tuition once. Many hospitals offer flex staffing options, so don't worry about your kids just yet. You are setting an excellent example for them in returning to school.
Good luck with your search!
