The "Back to School" debate

I only have about one year of school left before I will earn my Bachelors degree.  After I finished the Spring 2009 semester I gave birth to Lulu and decided to take some time off of school to stay home with the kids.  I have been debating when I should go back.  I've already been accepted to Old Dominion, but I'm just not ready to take that leap yet.  I'm intimidated by the size of the school, but most importantly, I think the kids still need me here, at home as a full time mom.   It's hard enough on them that their Dad is not home nearly enough due to his job.  I think they deserve the stability of at least one parent that can always be here for them.  I can't wait to get my degree, and it sure would be nice to have a second income, but for the time being, I'm needed here at home.
