My husband and I were very closed mouth about having children and none of our family members knew that we were trying. After we got pregnant and had some time for the idea to sink in, we bought 4 silver picture frames that were detailed for baby. We then made a picture on the computer with a stork carrying a baby and a message that said "Grandma and Grandpa (or Aunt Carri, etc), can't wait to meet you next April." We then wrapped each one as a gift. We bought four because my parents are divorced and my sister lives in another state, so we let each family find out by giving them their own "gift." For my in-laws, we waited until the next time all of the family was together and gave mom and dad their gift. It's the first baby in our families and it was really exciting for the grandparents to open the frame and be able to announce the news to the rest of the family. Plus, now they display the frame and wait for the day they can put a real picture in it!
