Neonatal nurse? Nurses that support new born babies. You could look at nursing programs at local schools.
Also being a nanny is a job that could help you through school...great nannies are very hard to find for dual working parents. Nannies in urban areas charge about $20/hr. To do this you'll need a clean criminal record check, basic baby CPR, and great references, plus the willingness to help out around the house. You could register with a nanny service or try to find a job through postings on facebook childcare groups or craigslist.
I have worked as a school nurse and a pediatric homecare nurse in the past. I enjoyed interacting with the kids.
