How to tell the world I'm preggers

J

I'm only 6 weeks 3 days with baby #2 and I've been thinking about how to tell my family. I keep telling my fiance, whose dieing to tell everyone that in January or February we can tell everyone. (I'll be 12 weeks January 5) well thinking in the shower today, it just popped in my head! our first born will be 18 months on February 14th. (also Valentine's day) so I was thinking about taking some cute pictures of my son showing how much he is grown and in one of the pictures have him wearing a shirt that says he is going to be a big brother. I'll write some sappy thing on FB about my son and fiance but make it long enough so people have to open up my post to read it and look at the pictures. I've had some lame ideas that my fiance has turned down but I think this idea is cute! thoughts? ideas?
