c section and preemie

Baby girl is came early. She's in the niccu and I had a c section. I'd like to return to work as I would much rather spend my 6 weeks when she comes home. Plus I can't afford to stay out work. My question is, any moms have this problem? When can I return to work after a c section? I have a light duty. Extreme light lifting job. I'd work during day and go up to hospital to see baby all night. My husband would spend the day there since he has 12 weeks of paternity leave. I only have 6. Advice? Please no judging that I have to leave my preemie. It's hard enough
