Beyond stressed about money- impacting my parenting

We have 3 kids, a singleton and a surprise set of twins. To send my kids to daycare it costs $500 a week. It is literally my entire paycheck after taxes and health insurance comes out to send my kids to daycare every week. They only go 4 days. We make ‘too much’ to qualify for any child care assurance, food stamps, or Medicaid. But we can’t make ends meat. I am donating plasma to get some extra cash, but I need ideas of what else to do. Side note: I have my masters degree and we both work at what is consisted ‘good jobs’

I am not about selling things to people, but any ideas of what I can do from home to make extra money? I have looked at other jobs with my degree ( in the social services field) and I haven’t found anything better pay wise.
