Thanks ladies for all your replies.

this morning we went for our 3d scan, and well we found out what we're having but have decided not to tell anyone else. I was surprised at my reaction, I was so sure it was the opposite to we're having, and I can tell from my reaction that I have a heap of expectations as to how important gender was. And thats even though I dont really mind what gender sprout is (I think it was added pressure from everyone around me, as to what they want us to have).
Funny thing though, Im still convinced that the sonographer got it wrong Maybe I can never be pleased?

But the 3d scan was awesome, it was amazing seeing what goes on inside of me And I can say sprout is just as cute as the big sisters!! (not biased at all either :P )
