I'm joining late to this thread. I agree "no" on FB. Congratulations on your upcoming milestone!
What I wanted to say is a warning regarding FB for those who still have their accounts. I read a blog post written by a woman in recovery. She's an older mom too with younger kids. Something just struck such a chord that I did something I've never done: I commented on her blog. But....it showed up in my FB postings. I mentioned something about recovery but it was kind of vague but still, I won't do that again. Keep that in mind if you have to sign into FB to write anything.
