We waited with both our girls. I know it would be just as much as surprise finding out at the ultrasound, but honestly, for me personally, I don't think anything could beat having the doctor lift up my baby and for ME to be able to say "I have a daughter!!!!" I was the one to announce the sex of both my sweet girls, and it's a moment I treasure.
And my husband got such a thrill out of being able to ring people and say "It's a Girl!!"
Decorating etc .. we kept the nursery gender neutral since it was going to be used by more than one baby, lots of bright colours. The girly touches came after the birth with special keepsake presents like music boxes and prints on the walls.
Clothing, I didn't buy much of beforehand anyway, just a couple of lovely white sleepsuits - I love newborns in white. I also had a beautiful pink baby shawl, and another one that was blue, given to me as never been used hand-me-downs which I took to the hospital.
And I never needed to know the gender to be able to "bond" with my baby ... I'm having a baby, a whole incredible new little person, who cares if it is a boy or a girl. After all, it is the time ever that I simply have a baby - not a boy or a girl, a son or daughter, pink or blue, just simply a precious little baby.
We are due again in September, my scan is next week, and we will NOT be finding out smile But yes, it is hard to hold out, but worth it in the end in my opinion.
Also helps that I don't have a desperate need or want for either a boy or a girl, so I simply cannot imagine being disappointed at the birth
