How do you organize child care as a single mother doing shift work?

FTM here hoping for some words of advice…I’m worried about finding flexible childcare, as my immediate family lives too far away to help me, and I work shifts 7-3, 3-11, and 11-7. How would I even function working a night shift and needing sleep but having to be up for babe? More child care to sleep? I fear this would deplete most of my income and I am stressing TF out! Please help me figure this out?
