ok, look at it like this: you have something wonderful to look forward to - a beautiful new child who will be just as wonderful as the one you already have; and I can assure you that being the mom of two children is a lot better than having just the one. yeah, ok, sometimes a little frustrating when they fight or argue, but most of the time it is good, and with a 2-yr difference they will be great friends to each other.
and I know you were traumatized in your first pregnancy but this is your chance to fix that! you know how they say, after a driver has been in a traffic accident it's important to get back to driving and not dwell on the negative memories?
this is your chance for you and H to take that tape with the negative memories from your first pregnancy, and overwrite them with wonderful memories from this one. and H needs to know it! that's the project for both of you.
good luck and I hope the pregnancy goes smoothly and pleasantly. hey, in a few weeks you'll be in the second trimester, that's the easy one.
