I'm on the website Coastie Chicks a lot and a girl on there made a post this morning about how her friend decided to find out and announce the sex of their baby.
The couple went to the ultrasound appointment and had the tech write down the sex on a piece of paper and seal it up instead of telling them. Then they took the piece of paper to a bakery and told them they wanted a cake made with white frosting and to make the inside of the cake blue if the paper said boy and pink if it said girl. Then they took the cake home and had a little gathering of family and friends and cut the cake. That way they could all find out together.
I thought this was such a cute idea! How fun to have all your friends and family around when you find out what you're having!
