Needing help with announcement ideas!

Kelly
So I'm 10 1/2 weeks pregnant with my 4th child. I have an 11 year old daughter and 3 and 4 year old boys. NO ONE knows yet that we are expecting. It's been so hard to keep this a secret, but we want to wait until we know the sex. I had the blood test done today to test for the 3 abnormalities and it also tests for gender, so we should know within 2 weeks. Anyone have any ideas of how we should announce it? My daughter is really wanting a girl,so if it's a girl I thought about having her do something. (She is the only one who knows)!!
