I don't know why informing people of status has to = them coming to the hospital.
I will call my mom when I start labor, just to let her know. I will probably let her know when we are admitted to hospital, too. However, everyone is on the same page that we will give a final call once baby's here and we are ready for visitors. I'm sure DH will do the same with his parents. And I'm sure my mom will call my siblings to keep them informed, too.
For everyone who gets so wrapped up in this being MY family, MY time, Me, me, me. You have to remember - you were that precious life to your mom, too :). 9 of 10 parents I know wouldn't need to come be in your face,mbut want to know where you are and that you're safe :).
