I was thinking of doing the same for our next bub (when it decides to happen) as it'll be our last. I think if we want to find out and not tell anyone I won't tell them we don't know, I'll simply say I'm not telling lol. Having said that, with DD we kept names to ourselves and got pestered (and even insulted!) about not sharing or welcoming others opinions so I'm expecting some very unhappy people when we cross that bridge lol. So I say find out and keep it to just you and your partner, it's nice to have a little secret every now and then
