Baby Bump....more like Baby Mountain

I am now 15 weeks along! Time is going by fast. And my belly is growing even faster. I remember wondering if I'd ever see a bump when I was pregnant with Grace. This time around, I swear, the second I saw that pink line, my belly popped out! I didn't believe the ultrasound tech when she said there was just one baby in there!
I think the time is going by so fast because I have been so busy. Nursing school is a whirlwind. I've never been so stressed out in my entire life! I feel as though I haven't gotten to really enjoy and bask in this pregnancy.  I have one more week until winter break. I hope I make it there! Poor Mark is feeling the wrath of my pregnancy hormones mixed with pure panic with school.  He is so good to me and I hope to repay him one day! He deserves whatever his little heart desires.
Mark has now taught Grace to point to my belly and say "brother". But then I ask her what she really wants and she says "sister". She lays her head on my belly and listens to the grumbling and thinks it's the baby talking. She is so cute when she hears something! She pops her head up and squeels! I love it.  I'm trying to relish every moment I have with her, knowing that our days alone are coming to an end. We will soon be a family of four! Crazy to think that! I never want her to feel jealous. She's my first baby! No one can take that away from us.
Nothing too weird is happening yet. I'm not craving anything specific. Except for Chex Mix. I'm still pretty tired, but I attribute that to my working over-nights twice a week. That's tough. And to Nursing school. I am counting the days to graduation, and I will NEVER look back to these days! And then right after graduation comes BABY! I can't wait to find out what it is! We will find out in a month. Boy or girl, we don't care.
