Good idea :) and thank you kaila
I would wait till you make the announcement of the birth :)
I'd probably hold off to be honest. you never know, you might change your mind a couple times before the baby gets here or your family might give you some negative comments that you don't want to hear. Whether you tell them or wait till baby is born, just remember that this is you and your Hubby's baby, you both are the only two that can decide on the name and how to spell it and what nicknames you might want to use, don't let any of your family make you feel guilty or dumb for something you like because its your baby(:
