I'd blurt it out LOL we have talked about wanting a baby so much that I don't think I could play cool and hold precious news from him a minute longer! If I can figure something out before I blow the whitsle I'll try it

As for my family-I think I'd blow up a sonnagram pic and tell them it was a magic eye picture and ask them to look into it and tell me what do they see?? LOL
