Very part time or PRN Jobs while in school (also SAHM)

I'm sure this question has been asked before. I'm in my late 30s, and stay at home with my toddler twins on the days I'm not focusing on school. I'm expecting to be accepted into my ASN program. I have no income, but my husband is carrying the household expenses.

I want to get a very part time, PRN, flexible job that is somehow related to healthcare. I want to do this especially before the clinical portion of my program when it will become more time consuming. My program required us to become CNAs before applying to the nursing program, so, I am certified. I'm also set to get my BLS soon. However my only prior work experience in the last decade is as a paralegal, and I have a good work history there. I have other assorted service industry experience from 20 years back.

Does anyone have any ideas? I could probably work 8-12 hours a week either remotely or on the weekend. I just want to have something health care related on my resume when I graduate, but my other "job" is staying home with the kids (so we save on the double childcare expense), when my parents don't have them so I can focus on school.
