Nope, you're not crazy. I found law school to be much easier than being a stay-at-home parent raising 4 kids . . . motivation and ability to manage tasks and deadlines is the real key. We've got lots of former military at my school; they kick butt. You'll probably do fine.
Well... there is always the reverse solution (which is what I did). Take a few years to make and raise a couple kids (I took 18 years, made four kids, youngest is starting 2nd grade this fall, oldest is a HS senior), then go to law school at age 40.
