How to tell people?

I've been trying to come up with some fun ideas how to tell our families. I thought it would be fun to order M&M's with a personalized "Baby #3 Oct 2008" on blue and pink candies. For me to order the M&M's, I have to order at least $100.00. I'm not sure I want to put that much into it. I don't want to have the t-shirts that say "big sister" or "big brother." I want it to be a little more original. I know M&M's aren't original but they cost so much that most people don't use them. I must continue my search...
