In all three of my pg's (even though 2 haven't gone to plan) we haven't even considered finding out the gender of our babies.

In fact my DH is dead set against it & I agree with him coz as he says "so few things in life are a real suprise anymore but the gender of a baby can be one of those few", so we never found out & I doubt we ever will should we decide to travel the pg path again.
