Nickle - I'm so glad your DS was okay, that would've been awful. I like the idea of saying straight out that you'll be referring to bubs as both he and she.

Corolla Chick - that's how I feel too, thanks!

Raffy - we sound very similar

Rowellen - that would be soo hard to keep from your DH!

LynsDan - good luck!

Charlotte91 - exactly

Okay, I think we're going to try our very hardest to keep it to ourselves...well I'm sure DH will have no problem, it's me that's going to struggle! Though I'm already getting pressure from people which is only making me more determined to keep a secret. Thank you everyone for your replies!
