Hey, I'm a Commercial banker in Manhattan....36, married 3 years with one kid on teh way....I took my LSAAT and got a 145...neeed to retake, might not start until fall 2010 now.....not feeling good about it, really wanted 2009 start.....any words of support would be greatly appreciated. 
I know it is hard to do, but don't feel discouraged. You have been blessed with having a child, and from what I hear (my husband and I are trying to have kids right now), that is the greatest blessing ever.

This way, you will have enough time to spend with your baby before you start the gruelling 1L experience.

As for the LSAT, you can definitely improve your score significantly! I was testing in the 160s (mid-to-high), but totally froze on the real LSAT and did not get much sleep the night before (my husband was snoring). I got a 148. Needless to say, I was shocked and mortified. I had never scored anywhere near that range. I also have been out of school for 10+ years.
I retook the LSAT 3 months later in a different location (
the test site can make a big difference - something to keep in mind), and I got a 157. This still is nowhere close to what I had been scoring on practice tests, but, again, I did not sleep the night before...my husband again was snoring, and I get pretty bad panic attacks during tests (which I need work on)...but I figure if I get a good night sleep before the next LSAT (I will be sure to have my husband sleep in a different room that night so that his snoring won't keep me up), I *hopefully* will get a score in the 160s and maybe even in the 170s (hoping for at least upper 160s).
Anyway, this is just proof that the LSAT measures virtually nothing (if you can have a 20-30 point deviation depending on the day / time, that means that the test is very prone to luck / happenstance IMHO).
Notwithstanding all of this, my score of 157 was enough to get me into a top 100 / regional school so I have toyed with going there, but think I will probably just retake the LSAT next year to get into one of my target schools.
I am going to try to calm my test anxiety through taking a dedicated prep course rather than just studying on my own, am going to study with some friends who are actually good at taking standardized tests (I am not naturally a good standardized test-taker...it is a skill / art IMHO), and am going to just pray that God's will will be done.
I feel like with the economy in tatters as it is now, law firms laying off people by the dozens / hundreds, and me being gainfully employed, going to law school right now probably makes no sense. In a year, hopefully, things will be more settled in the economy and, quite possibly, law firm salaries will shrink meaning that some people who were going into the field for impure reasons (e.g. for the money) will rethink taking on such a sizable amount of debt for such uncertain returns / salaries.
Lastly, just as an FYI, a lot of law schools are taking the higher of the LSAT scores since that is all they have to report for US News & World Report nowadays. This - I think - helps people like you and I who bombed one of their tests.
Just my two cents. I hope this helps you and brightens your heart and your spirits today!
