When did some of you ladies do your hospital tour? I'm 22w6d and although Ive used the hospital I'm going to deliver at since I was born for anytime I had to go to the hospital, I'm not familiar with their maternity ward or anything since I'm a first time mom and my parents only child, and everyone else I know delivered on a different campus of that hospital which at the time that they delivered was under a different name and under different staff and management (my hospital bought out and merged with the other local hospital so now it's all one just 2 different locations.).
