Telling LO the morning of the RCS?

Mrs.RockyM

We're scheduled for the RCS at noon, and don't need to be at the hospital till 10 so we were thinking we'd drop DD off at daycare before heading over to the hospital.  We're not sure if we should tell her that morning, that mommy is going to have the baby today, or if we should just wait and have my mother tell her when she picks her up at the end of the day.  We're hoping that she can come by after dinner to visit, but it all depends on how I'm doing and feeling. 

What did others do?
