This is hard to figure out because you're a non-trad: having been out of school for a few years and now being a parent. As well, law schools are very concerned about their numbers, but since you'd be applying to PT programs, your numbers don't go into calculating their numbers, so they can be a little more forgiving of a lower GPA or a lower LSAT score.
That said, Fordham is still the middle of Tier 1, so I think you're still going to need to pull out a strong LSAT score to compensate for your GPA, 160+ (I imagine), to convince them that you can do the work. But, again, who can say what your non-trad "soft factors" will do for you? Re: Rutgers Newark and Seton Hall, a 160 seems to be almost a lock for the first and a definite lock for the second with your GPA, but, again you have these other factors as well as your scores not affecting their numbers, so maybe even being below their 25th %iles (155 and 153, respectively) wouldn't hurt too badly, either.
So, I say, if you put together a solid application with a good PS and strong, supporting LORs, then a 158 is probably the lowest you can score and stand a good shot at getting into Rutgers and Seton. I would argue that slightly lower than 158 might not get in your way, but then you really can't be certain of anything (but when can you ever be certain, really?).
I recommend asking this question on the non-trad board here and see if anyone there has similar GPA and LSAT potential or circumstances. They would definitely know better.
Thanks a lot for the advice, I'm gonna post this on the non-trad board in hopes of getting some more replies
