We have a lot in common! I also have 2 crazy boys and a husband (I got a girl dog and cat to get even). Some community colleges offer evening and weekend clinicals, for example Villa Julie College in Baltimore, Maryland. My Mom's advice was great when I said the same thing as you a few years ago. "Just go to the college. Go there, get the information, and sign up for whatever class you need. You'll figure out the rest from semester to semester."
Get a loan or tuition reimbursement from your job. I went from a $30k/year job to being a waitress for 2 years while I did my early classes. I made decent money with no childcare costs. Now I work Part-time in a hospital as a secretary evenings and nights, and they pay for my school. Most of the students in school with me have young kids, some are single mothers. My good friend in school with me has triplet boys, aged 5, one of whom has Down's, and a 3 year old girl. She doesn't have extensive child care, and she gets A LOT OF MONEY FROM SCHOLARSHIPS
, GRANTS, and LOANS!!!!! There's a lot of money out there for nursing students. Start by seeing an advisor. They'll get you pointed in the right direction. Follow your heart -- you'll be rewarded tenfold.
