We have 2 DD's and w/DD#2 we didn't find out the sex, I had a hunch she was a she, DD#1 knew it was a she...we also had a weird incident at my baby shower...
The cake was ordered by my sister, i didn't know what it would be except it matched the theme (pea in a pod, greens/yellows). It turned out to be a lovely cake with a baby tucked in a blanket of frosting. When we were prepping to cut the cake I pulled the baby out of the frosting, revealing it's PINK outfit . My sis was guessing a boy so I know she didn't order it on purpose! Everyone was convinced it was a sign, and we would have a girl..which we did. The ultrasound tech also accidentally mentioned "she" once during one of my NST's towards the end of the pregnancy (ordered because our LO was tachychardic).
My only reasoning for guessing boy is how different this pregnancy is (nausea, lack of VERY tender boobs, exhaustion, etc).
As PP's stated above I'll be happiest w/a healthy LO to add to the mix, boy or girl. And as with out last pregnancy, we will NOT be finding out the sex. It's the best suprise in the world!
