I told the world
In fact, we told them all within a few days of getting the home positive. I was trying to think of a cute way to tell them all, but I didn't come up with anything, so I just posted it on our webpage, then waited for the phone to start ringing!
My thoughts on it is that if we were to have another miscarriage (had one between our boys), then I'd want the support from friends/family. I don't want to suffer in silence. It would be hard to tell everyone, sure, and in the event that somehow someone (coworker, obscure family member, etc) didn't find out about the m/c and asked about the baby later, it would be awkward. But I don't want to keep that to myself either. A pregnancy means a new life beginning, whether that life makes it to birth and after, or if it ends too soon, it deserves to be celebrated. My thoughts anyway
Plus, I get awfully sick, I show very early (there's no hiding this pregnancy now and I'm only 10 weeks!), and I like the support from coworkers and neighbors who offer to help with my other kids.
None of our family lives near us, which is a good thing sometimes (no one looking over my shoulder, judging anything I do or don't do) and a bad thing sometimes (no extra support, no one to share in the joy) But we lived literally half way around the world (Japan) when we had our first baby, so we're used to doing this on our own
