Terminate child support in LA, CA

Hi everyone after 8 years my bd and I decided to rekindle, it’s been about a year and we actually just found out we’re pregnant with twins. We plan on moving out together in December my question is, since I am high risk (not working) I started getting cash aid and food stamps. I want to know if anyone can help me with this process. Please, I’ve been stressed about this topic because we both don’t want this open anymore and want to just close this chapter already, thank you.
