LOL...we're in the same boat. Except I'm pg (with a boy...that I thought I didn't want) and my sis is 8 weeks behind me. I just know she's having a girl (she finds out in a few weeks). It took me about a month, but I'm finally feeling excited about this boy. I am nervous however about how I'll feel if she really is having a girl.
My parents tend to lend more help to my other siblings too--but it's because they need it. Sometimes when I'm feeling jealous I just remind myself that I wouldn't trade my life for theirs for all the help in the world.
Is there any hope for a DD for you or are you done? I have a DD and wanted another (never even considered wanting a boy). I don't think I want anymore kids, but I'm wondering if I might always wish for that second DD??
