I'm in the same position. With DS we found out and were happy to tell friends/family that we knew but not to say what we were having, however by the end everyone had picked up on a comment or something along the way and it was common knowledge that we were having boy.

This time round we again wanted to know but have decided to keep it to ourselves, so we have told a little white lie and said that we don't know. I know with friend who have found out, but haven't told it has always been fairly easy to guess based on comments they have made so I think a little white lie doesn't hurt.

As far as pros and cons, I always get a little bit more excited waiting for baby news from family/friends when I don't know what they are having, but that is just me. And getting present in neutral colours can be a good thing if you plan to have more babies!!

GOOD LUCK!!!
