You may find that you change your mind about this later. It's funny, but DH and I have both commented that we actually have forgotten about it more of the time than not. It's just not an issue. Our little girl is ours.
Anyway, always remember that once you've told, you can't un-tell. And, interestingly someone did a research study (it's posted somewhere on the DE board, but I have no idea where) looking at DE parents and the one thing that came out of it was that the majority of parents in the tell group later on wished that they had not told others.
Anyhow, I'm glad to hear that being back at work is working out for you. Definitely, health insurance is a big need that no family can do without these days.
