Going back to school?

Is going back to school worth it? I’m thinking about going back to college to do something in the medical field, either Phlebotomy or Heath information management and I’m not sure if it’s worth it. I already have a one year old and another baby on the way in June. I’m not sure how I’m going to pay for it because I think my husband makes to much for financial aid. 🤷🏻‍♀️ I’m not sure what to do.
