Wanting to stay at home...

I am wanting to stay at home, once our son is here in March. We both come from working family’s and I want to be there with my son and take care of my husband. <-this has always been my dream. But I have no idea how to do this. I make $20/Hour and he makes $16/Hour so if I leave we loose our bigger income and better insurance.

What to do?

I do have a BA in Psychology so idk if there is something I can do from home. SoCal living.
