We've told our immediate family and a few friends. I was going to tell my grandma last night when I called her to say happy birthday, but she wasn't home -- I really should tell my grandmas though because I want to tell them before it gets out, and my mom has been dying to tell people. She says she can't believe how many people have asked her lately when we're having another

I guess it's the expected thing when you have a child over 2?
I haven't told work, am trying to wait until 12 weeks but may tell after I see the m/w next week, because I have a belly, so no doubt rumours are flying.
Last time we waited until 12 weeks to tell anyone, but this time we decided, well, we'd turn to our family and friends if anything was to happen, so why not tell them now? This is a personal choice though. And work is not included, I would not share any bad news with them if I didn't have to, hence the wait!
Funny thing, last time we didn't see FIL until around 15 weeks, and told him then. His response?
If it were me, I wouldn't tell anyone until I was showing, I wouldn't want to tell anyone if something went wrong. So, we were in no rush to tell him any earlier this time. But we forgot to mention that to SIL and BIL so of course it got out, and he called somewhat disappointed. But when DH explained why, he said he did remember saying that and so did understand why we held off. Phew.
