Krystal, I went back to school for my Master's when I was seven months pregnant with my first! I'd recommend your method over mine! Have fun with it!!!
I got halfway through my MBA when I got pregnant with DS11. I never finished, and now I'm heading towards a different MS. Unfortunately, it's a bit of a shift so I have to do some undergrad first. The question is, how much undergrad? I'm still trying to find out.
