Congratulations!!!!
My family also waited a long time for us, we took our time before deciding to get pregnant.
Here is how we told them: We invited them over to dinner (which we do a few times a month) and told them my husband had been on the news and interviewed in a segment and we had recorded it for them to see. When we played the video it wasn't of the news, it was of our little peanut in her first sonogram video. THEY FLIPPED! We hid a video camera and recorded their reaction. So glad we did!
