Is it tacky to announce a pregnancy on a family blog

Just wondering. I know we announced Maddie via email. Baby #3 is due Dec 15. So, J, I'm not apologizing for pushing you for a wedding date. It kind of matters to me more than it usually would this time (don't be mad)...and I'm not missing the wedding. :) The doctor was willing to take Maddie a week early, so maybe we can have it on Dec 8, which gives me plenty of time to be ready to fly by Dec 27. Love, Angie, Brian, Ben, Maddie Mae and #3
