I think you should ponder SourLemon's question about why you see nursing as the answer. Maybe you have some undisclosed reasons that you didn't share with us, and that's fine. But if you think nursing will be "easy" or a good way to get rich, you need to reconsider.
Next, do some research on LPN salaries in Florida. A quick search tells me that an LPN in Miami makes on average 41k/year, while in Pensacola the average is 36k/year. Those are averages, and you'll make less than that starting out. Staying in Mass might allow you to complete your RN and make a decent wage, but it seems like going to Florida where your parents are would allow you to have some help with childcare. Why not look into RN programs in Florida?
Finally, your GPA doesn't necessarily exclude you from an ABSN program. There's a thread (Non-nursing degree (low GPA/stats) to accelerated BSN program?
) all about low GPAs and what people did to improve their chances at getting into ABSNs. There are some lower-tier schools (not necessarily for-profit schools, either) that will accept a lower GPA, and there are a lot of schools that use a holistic approach and look at other factors besides GPA for their admissions criteria. Most students with a low GPA from their first degree make sure to really ace their prereqs, and you would be wise to do the same.
