One more thing I forgot to mention --
I still haven't told my Mom we're planning to conceive. But I did mention the recent adoption offer incident (which, by the way, fell through) and how Rachel was disappointed. She even spoke to Rachel on the phone about it and according to Rachel, seemed sympathetic. I'm not sure I got that same vibe, but at any rate, the fact that I was able to talk to her about that without her flipping out or saying anything really negative is good.
Just thought I'd share.
