I let the cat out of the bag that I was pregnant with Ady. I had found out myself on St Patrick's Day and slowly started telling folks that needed to hear it directly from me.
Then I sat down and typed out an email to all the other people that I needed/wanted to tell but didnt need to sit face to face with me to hear it..I got a lot of replies back that night asking my if it was an April Fool's joke...I hadn't even thought about it being April 1 when I sent that email out.
Ironically, today a friend of ours let her cat out of that bag that she's pregnant!!
