I am the worst secret-keeper in the world, so this part is AGONIZING!
So far, my best friend, her husband/mom/dad, and MDC know. I'm sure it makes me a horrible wife for telling the best friend and letting her tell her family before DH knows, but he's out of town and I REALLY want to tell him in person... and I had to tell SOMEBODY!
I'm scheming different ways to tell our families - MIL, FIL and SIL will be visiting us on Mother's Day, so I'm tempted to give MIL something having to do with grandmothers. I'd like to do the same for my mom, who was planning to visit at the same time, but now it looks like she won't be after all so I'm not sure if I should mail it and have her open it on the phone, or what...
My sister and I have a running joke about a friend of hers who, at nine months pregnant, said "I'M SICK OF BEING PREGNATE!" on her MySpace... And was dead serious. I don't know how you can be about to give birth and not know how to spell pregnant. Anyway, I'm going to tell my sister I'm pregnate, too.
Grandma who might end up sharing a birthday with the baby will probably get a phone call... extended family/friends will probably find out through the grapevine, assorted phone calls, MySpace, etc.
Does anybody have cute stories about the way you told your DH/DP? I'm trying to figure out if I just want to tell him I'm pregnant the minute he walks in the door, tell him he's going to be a dad, make him a nice dinner, give him a test, give him a book, etc... I have a bazillion ideas but none of them have seemed perfect yet.
