Well, you already don't work, and you have support. You have the best you're going to get right there.
If you get a BSN now and do the hard work, you won't have to worry about going back later on and paying more money for a bridge program.
I have a 3-year-old, do not work, and I'm in a BSN program full-time, too. It's not easy...but goodness, I'm not in an accelerated program, though. Those are rough. Just remember that passing is passing. If you need to put down your homework for an hour to play with your child, by all means do it. I don't break my back to get perfect grades, and I think as parents, we should cut ourselves some slack. I applaud you for working so hard!
