I'm torn on this issue this time around.
We found out with our first two but not our third. I really kind of liked not knowing. Made labor more fun b/c there was another element of surprise to look forward to.
I think my dh would like to know. I do only because if it is a boy, I need boy stuff. :LOL I have NO boy clothes, blankets, diapers, etc.
If we do find out, I do NOT want to tell dh's family.
They are so obsessed w/ having another boy in the family. His parents have one grandson and six granddaughters. We told his mom last night and instead of all the Congrats and hugs....she talked about how neat it would be if this were a boy since the oldest grandchild is a boy.
