One of the reasons we didn't find out was because we'll love it regardless. The family tree on dh's side has been only boys for generations, so to avoid gender disapointment (not that I had it but in case I did). If I'd had had gender disappointment and found out at the scan that it was another boy, I'd have the rest of the pregnancy to deal with it... If I found out at birth. BAM baby is there and I have instantly fallen in love with this newborn. I hope this makes sense.
