I'm going to have a lot of fun trying to guess if this little bean is a boy or a girl. I have one of each and my two pregnancies were very different. Pretty much everything was opposite. I'm starting to keep track of things and so far I have two marks in the boy column and zero in the girl column. What tells me boy so far is that I'm absolutely freezing and I felt my first twinges of morning sickness today at exactly 5 weeks, same as with my son. With my daughter it was at 8 weeks, less severe, and lasted for only a couple weeks.
We want 4 children, so I don't really have a preference either way for this baby. I really want to have 2 of each when all is said and done. And not just for my own sense of "complete", but because I really want all of my children to have at least one of each sex sibling. Obviously, whatever happens happens, but I like to imagine. :)
